- New DATs: GameInit.dat (https://www.progettosnaps.net/gameinit/)
- CPU
  . Analog Devices ADSP21062 'Sharc': Simplify execution of rotate instructions (no need to switch on sign). Added macro to force unsigned register readout (sharc\sharcops.hxx).
  . ARM7
    . Bugfixes and updates: Fixed multiple issues with ARMv3 parts that dynamically switch between 26 and 32 bit modes. Added ARM610 model for RISC PC 600. Allow ARM926 to execute code from the instruction TCM. Debugging assisted by Claude Opus 5. Added DEC SA110 variant with correct flags, (MESS) sarpc_j233 boots (arm7\arm7.cpp). Simplify handling of unaligned reads (arm7\arm7.cpp).
    . Many fixes: SMLA* instructions were doing the wrong operation. QDADD/QDSUB weren't saturating the operand. Some forms of Thumb BLX were not decoded properly. BKPT was mis-decoded as MSR, which trashed CPSR. Thumb ADC ignored the incoming carry flag. Data aborts ignored the high vector flag. BLX LR in ARM mode did things in the wrong order. MRC with R15 as the destination was supposed to update flags, not the PC. LDR* R15 set the PC to the wrong value. Some undefined opcodes were wrongly executed as LDR/STR. Undefined Thumb instructions weren't generating the UND exception. v5TE DSP ops worked on v4 emulated parts. PLD is v5TE, not v6. LDM*/STM* with an empty register list are NOPs. Disassembler was wrong for SMLA* and SMUL*. ARMv3 was mishandling CP15 writes. Tested on a bunch of drivers including the (MESS) newton.cpp (NewtonOS now boots), the 39in1.cpp gang and more. Audit and debugging assisted by Claude Opus 5 (arm7\arm7.cpp).
    . Align the PC corectly for ARM vs. Thumb mode on return from an IRQ/exception. Fixes (MESS) Nintendo DS booting into the dashboard. Bug tracing assisted by Claude Fable 5 (arm7\arm7ops.cpp).
    . Fixed 26-bit mode regression introduced by the previous NDS fix (arm7\arm7ops.cpp). Completed the recent 26-bit mode work so this core is now the single source for pre-AArch64 ARM implementations. Also fixed LDM with a banked base in the list, necessary for RISC OS 3's FPEmulator (which was broken on the old core too, for a different reason). Fixed LDR/STR R15 handling in 26-bit mode, which tripped up the aa680 boot ROM. Claude Fable 5 assisted with planning, the mechanical refactoring of the drivers, and the generation of a "before and after" test suite (arm7\arm7.cpp).
    . Fixed LDR/STR order of operations and don't nuke the registers when resetting. Makes RISC OS much happier (arm7\arm7.cpp and arm7\arm7ops.cpp). ARM710T is a 32-bit-only part with Thumb, not a 26/32 hybrid. Fixes (MESS) Psion 5 MX PRO (arm7\arm7.cpp). Charged the proper cycle count for shifts where the count comes from a register. Fixes (MESS) tascr30 speed detection (arm7\arm7ops.cpp).
  . Atmel ATmegaXXXX: Added pin-change/external interrupts, real GPIO DDR/PORT semantics and full-duplex SPI shifting. Added PCINT0-2 and INT0/INT1 support: pin_change() latches PCIFR/EIFR from a possibly mid-instruction external write, and the actual interrupt is taken at the next execute_run() instruction boundary. INT0/INT1 sense mode (low/change/falling/rising) is read from EICRA; PCIFR/EIFR are write-one-to-clear. Added ddr_w(): each port's DDR is now tracked and drives the gpio_out callback together with PORTxn, so an input-configured pin floats (reads as 1) instead of being pulled by the last PORT write. Rewrite spi_tick() to actually shift MISO into SPDR (previously only MOSI was ever driven): samples MISO on the SCK rising edge, supports DORD, and sets SPIF/raises the SPI interrupt when the byte completes. spdr_w() now clears SPIF and resets the shift state on each write, and disable_spi() actually stops an in-flight transfer. Added sleep mode (m_sleeping) and ATmega1284 device support. Misc: timer0 normal mode now actually counts/overflows instead of logging "unimplemented"; EEARH masking goes through eearh_mask() instead of a fixed EEARH_MASK. Updated comments. Provide devcb-compatible port bit writes. Assisted by Claude Sonnet 5 and GPT-5.6 Sol (avr8\avr8.cpp and avr8\avr8ops.hxx).
  . Fujitsu Micro F2MC-16: Revert MAME 0.289 changes (External interrupts do not seem to have a iack/vector fetch cycle) (f2mc16\f2mc16.cpp). Fixes black screen and freezes MAME at start in Motocross Go! and clones (ID 09509).
  . Hitachi H8
    . Use logmacro for verbose logging (h8\h8_timer16.cpp). Minor logging fixes (h8\h8_dma.cpp and h8\h8_sci.cpp). Fixed logerror bug that caused assertion failures in (MESS) jv880 and rd500 (h8\h8_timer16.cpp). Quiet default logerror (h8\h8_timer8.cpp).
    . The H8-3006/7 bit 7 for port 6 is weird: It's always input while its ddr bit always says output (h8\h83006.cpp and h8\h8_port.cpp).
    . Fixed flags for 8-bit SUBX. Fixed byte-wide forms of 'CMP EA', #imm' and 'MOV #imm, EA'. Added undocumented LDC/STC byte-wide behavior that Roland relies on (h8500\h8500.cpp). ixed word-size LDC/STC EP to save/restore the EP:DP pair, which the (MESS) Alesis QS IRQ handlers definitely assume (h8500\h8500.lst).
    . Map the H8/510 watchdog timer registers and port 8 resets to inputs. TCSR/TCNT at FF10-FF11 were inside a disabled block. The SC-88 firmware assumes the ports power up as inputs (h8500/h8510.cpp).
  . Hitachi SH7xxx/SH-1/2/3/4
    . SH family updates: Removed shadow m_am member that was causing confusion in favor of the base class's. Exception vector fetches now mask the fetched PC with m_am. Fixed DRC cycle counts for MULS, MULU, BT/BF, TSTM, BSRF and STC/LDC. Fixed interpreter cycle counts for JMP, ORI and ORM. Fixed interpreter MAC.W and MAC.L to generate correct results. Illegal instructions now trap when they happen instead of some time later. generate_delay_slot() propagates the delay slot's cycle count back to the caller. Fixed DRC delay slot behavior for BSRF, BRAF, JSR, JMP, RTS and RTE. MOV.W @(disp,PC), MOV.L @(disp,PC) and MOVA now use the correct address when in a delay slot. RTE restores PC and SR before the delay slot executes and properly masks SR. LDC.L @Rm+,SR masks the loaded value with SH_FLAGS. SLEEP now actually sleeps on the DRC, it was a no-op before. The FPU now uses the requested rounding mode for both interpreter and DRC. Correctness fixes for the interpreter versions of FTRC, FDIV, FSQRT, FSRRA, FMAC, FTRV and LDS. Fixed 11 cases of copy-pasted very broken UML_TEST (..., m_fpu_pr, 0). DRC FNEG inverts the sign bit in both precisions. DRC FTRC routed to the range-checked implementation. All seven DRC FMOV forms converted to UML via generate_fmov_single/generate_fmov_pair. DRC FLDS, FTRC, FSQRT, FSRRA, FCNVSD, FCNVDS, FIPR and FTRV converted from cfuncs to UML. DRC CLRS, SETS, SHAD, SHLD, LDCDBR, the banked STC/LDC forms and the @-Rn/@Rn+ control-register transfers and LDS/LDS.L to FPSCR converted to UML. Func_FSSCA applies the rounding mode before calling the interpreter. Tested to fix a selection of Saturn software that was marked "doesn't work on DRC" and to generate byte-identical 3D frames between the interpreter and DRC with 6 Naomi games. On both x64 and arm64 hosts and even x64 vs. arm64. Additionally, a generated Lua script performed an FPU torture test which found and verified many of these issues. Debugging and tracing assistance and some suggestions on fixes were provided by Claude Opus 5. Fixed things that should be in the DRC cache.
    . A few cleanups: Flip the interpreter's policy to run primarily in the host's rounding mode and only set ours when necessary. Moved m_fpmode into the cache for further x64 safety. Added the necessary #pragma for FP environment changes on Clang. As far as I can tell, GCC wants per-file -frounding-math in the build system for this, and ditto drcbec.cpp. That's a relatively big change for two things that won't normally be used though (the SH interpreter and drcbec).
    . Added SH7016/SH7017 mid-speed A/D converter. Fixed the SH7014 SCI's asynchronous frame and bit rate. The frame format had all three of its fields the wrong way round. A port set up for 8N1, as MIDI is, was receiving 7E2 and framing every byte. The internal bit rate was short by the factor between the peripheral clock and the bit clock. Expose the receive input, which had no accessor. The SH7014 SCI loads on a falling TDRE only, and its requests are levels. Fixed SH7014 watchdog timer. The SH7014's DMAC restarted every transfer it finished. The SH7014's IRQ pins have vectors and priorities of their own. sh7014 edge-detected IRQs never reached the CPU (sh\sh7014.cpp).
  . IBM PowerPC
    . Help performance on PCI PowerMacs with a 68K DRC: * Apple's 68k DRC frequently generates a code sequence, flushes it, and then regenerates the exact same thing at the exact same address. So we now cache small sequences and can restore them without the overhead of a recompile. This required adding some accessors to the 3 DRC backends. * The entire vTLB (a MAME DRC implementation detail, *not* the 603's architectural TLB) was being used as a comparison for deciding to flush a block rather than just the actual mapping. In particular, the access count bits were causing unnecessary recompiles. * The vTLB was also too small: at its original size it covered just 512K of working set. By trial and error stepping through powers of 2, 4096 was found to give the best results running real Mac software. With these changes, pwrmacg3 went from roughly 160,000 block flushes and recompiles per second to 0 when idling at the Mac OS 8.1 Finder. This also smoothed out regular audio breakups on pippin caused by recompile storms and seems to have even sped up a few of the PPC arcade games by a few ticks. Claude Opus 5 assisted with measuring and isolating the performance issues n (powerpc\ppc.h, ppccom.h and ppcdrc.cpp).
    . Generate the no FPU exception when MSR[FP] is cleared, and added a temporary opt-in hack for some cache-reliant (MESS) Mac OS 9 behavior. Fixes garbage window backgrounds in the Finder and elsewhere on PowerMacs. Claude Opus 5 assisted with tracking down these issues (powerpc\ppc.h, ppccom.cpp and ppcdrc.cpp).
    . TLB fixes exposed by (MESS) Mac OS X (powerpc\ppc.h and ppccom.cpp). Respect the ICFI bit in HID0, fixes regressions in Konami M2 games. Finding the bug was assisted by Claude Opus 5 (powerpc\ppccom.cpp).
    . Fold CTR-only branches. Branch folding wasn't implemented for bdnz/bdz instructions. This caused the Power Macintosh 6100 ROM's calibration loop to be off by 1 cycle and miscalculate the CPU clock (powerpc\ppcfe.cpp).
    . Fixed Mac OS X kernel panics freezing the MAME process (powerpc\ppcdrc.cpp)
  . Intel I386: Fixed rotate (i386\i386op16.hxx). Fixed stmxcsr typo in disassembler (i386\i386dasm.cpp). Correct CPU generation flags for several opcodes (i386\i386ops.h).
  . Intel P8798
    . Timers run three times too fast. timer_value() and timer_time_until() are in cycles, not input clocks, so divide down accordingly (mcs96\i8x9x.cpp).
    . MULB indexed byte operand and HSO CAM entries lost to exact-equality matching. mulb with an indexed byte operand must read a byte. Fire HSO CAM entries on reached-or-passed, not exact equality. Co-authored-by Claude Opus 5 (mcs96\i8x9x.cpp).
  . MC68340: Implemented DMA transfers and external interrupt handling. Convert the DMA module to a device and implement dual-address transfers, external request handshakes and interrupt arbitration. Support configured external autovectors and restrict MBAR accesses to CPU space (machine\68340.cpp).
  . MOS Technology 6502
    . New cycle-interruptable 65816 core (WDC W65C816S) using the existing m6502 generator infrastructure. Switch (MESS) apple2gs.cpp to W65816 and bus\adb and default to the correct LLE A9M0330 keyboard and A9M0331 mouse. Claude Opus 5 assisted with conformance testing and a final refactor and cleanup pass (m6502\m6502d.cpp and m6502\m6502make.py). Include w65816 as an option (tools\unidasm.cpp).
    . Implemented RDY input (m6502\m6502.cpp). Assisted by Claude Opus 5.
    . Fixed interrupt sampling on the NMOS variants. Latch interrupts before each bus cycle, except the opcode fetch that follows. This makes the effective sample point the instruction’s second-to-last cycle. Do not sample interrupts on the second cycle of a taken same-page branch, during BRK/interrupt vector fetches, or directly at the vector pull when an NMI takes over a BRK. For that NMI case, latch it before the status push instead. Assisted by Claude Opus 5 and GPT-6 Astra (m6502\m6502.cpp).
  . Motorola MC68030: Fixed CACR mask for '030, was causing a few Macs to misdetect as an '040 (m68000\m68k_in.lst and m68000\m68kops.cpp)
  . Motorola MC68040: On the MC68040 CACR reserved bits must read as 0 (m68000\m68k_in.lst, m68kcpu.h and m68kops.cpp), fixes Amiga CPU detection (GitHub #15792).
  . Motorola MC68HC705xxx
    . Added SCCR1 and BAUD register stubs. Added remaining SPI and SCI registers. The mc68hc05c8a datasheet notices that these two are short by 4 bytes. This corrects the error (m6805\m68hc05.cpp).
    . Added SPI and SCI IRQs. Consulted the mc68hc05c8a and MC68HC05C4 documents. Label SPI and SCI vector with part family. Makes the vectors specific to the C family of these parts. Updated Vector Naming (m6805\m68hc05.cpp).
  . MCS-48: Added Fujitsu MB8881 variant of Intel 8039. Added one character to flags string specifier (from 11 to 12), stack bit 0 was not shown (mcs48\mcs48.cpp)
  . NCR 53C7xx SCSI
    . Initial support for the NCR53C710. Split the generic ncr53c7xx_device into ncr53c700_device and ncr53c710_device. Changed register defines into constants. Convert the UNIMPLEMENTED define into a function. Correct DCNTL bit definitions and implemented manual-start. Correct SCSI selection to present both initiator and target IDs. Added target BSY waiting. Correct SFBR to latch the first byte of each Block Move. Added masked SFBR comparisons for Transfer Control instructions. Correct Block Move opcode widths and rejected reserved initiator opcode 0. Implemented 53C710 specific software reset and SIGP handling. Support big-endian mode on the 53C710. Added 53C710 table-indirect Block Move and selection operands. Added 53C710 register/SFBR read-modify-write SCRIPTS instructions. Added 53C710 memory-to-memory moves. Added relative Transfer Control addresses. Implemented SIGP wakeup from Wait Reselect. Improved logging. Added SCRIPTS disassembly for the newly supported 53C710 instructions. Added working SCSI support to the Amiga 4000T driver. The system successfully boots now instead of hanging while checking for SCSI. GPT-5.6-SOL was used as a research and debugging tool (machine\53c7xx.cpp).
    . Fixed some issues shown by the ReAmiga diagnostic test: Don't fatalerror when the DMA watchdog is set. Honor memmask on writes to the TEMP register. Implemented CTEST5 ADCK and BBCK manual DMA address/count clocks. Implemented ISTAT software resets. Gate external interrupt by SIEN and DIEN. All tests now pass except for the FIFO and low level tests. GPT-5.6-SOL was used as a research and debugging tool (machine\53c7xx.cpp).
  . NEC V60: Incorrectly printed opcodes DBLT/DBLE/DBV/DBNV in disassembly. Latent issue with incorrect opsize usage in disassembly. Stale m_amflag caused segfault (v60\am2.hxx, v60\op12.hxx and v60\v60d.cpp).
  . NEC VR5500: NEC VR5500 has unique page mask and Config encodings vs. stock MIPS III. Fixing this allows jnero to write a correct display list instead of garbage (mips\mips3.cpp and mips3com.cpp).
  . Philips SCC68070
    . Fixed UART Status. This change fixes several issues in the UART for this device. This has the effect of resolving some errors in the CD-i bios tests. Previously, UART would flag as Ready on every callback. Now it won't identify as ready while a transmission is currently queued. It would also preserve the Break flag on reset. This change correctly resets the Break flag. Finally, this unsets Ready when transmitting a write (machine\scc68070.cpp).
    . Fixed I2C Mismatch. The bits in line 612 don't match line 492 where I2C level is reset. It seems to be accidentally copying the m_uart_rx_int value instead (machine\scc68070.cpp).
  . Sony CXD8530xx/CXD86xxx (PSX CPU): Moved ram_device into drivers, support all ram window sizes and mirror 0x1fc801xxx registers at 0x9fc801xxx & 0xbfc801xxx (psx\psx.cpp).
  . ST0016: Primary implement tilemap scroll. Use tilemap_t for tilemap. Added notes about tilemap scroll register and tilemap registers. Fixed code style (seta\st0016.cpp).
  . Toshiba TMP90xxx/TMP91640: Fixed CPIR infinitely looping. Combined LDI/LDD and added CPD (tlcs90\tlcs90.cpp).
  . Votrax SC-01/-A: Fixed a sign error that can make the SC-01 F2 noise-injection filter unstable for valid internal ROM states (sound\votrax.cpp). Fixes sound cuts off in Q*bert and Q*bert's Qubes after a while and doesn't come back (except for the knocker) (ID 09521).
  . Zilog Z8001/2: Correct CPU/MMU behavior. Fixed addr_to_reg segment mask to replace full high byte. Fixed MULTW carry-flag boundary. Preserve DIVW/DIVL quotient on representable overflow. Toggle H flag in COMFLG. Write POPL @Rd,@Rs result to memory. Read indirect MULTL operand from memory. Fixed dynamic shift dispatch and count sign-extension. Fixed RRDB temp register and RLDB/RRDB S flag. Accumulate V flag across shift/rotate steps. Fixed compare-string repeat and block-move Z flag. Fixed SOTIRB/SOUTIB source not incrementing (bumped segment word instead of offset). Fixed block-I/O instruction flags and address increment. Fixed COMB @Rd destination register decode. Trap the 4F extended EPU family at the correct instruction. Preserve the indexed LDA operand across an overlapping destination. Derive the DAB correction table from measured Z8001 behaviour. Leave the tcc destination alone when the condition is false. Fixed the MULTL carry boundary. Take the DIV overflow sign flag from the whole quotient. Order the translate RH1 writeback against the pointer step. Replaced the whole high word when writing a segmented address back. Do not mask PSAPSEG through LDCTL. Read a byte for the non-indexed COMB. Do not mask the FCW written through LDCTL. Calculate DAB correction directly (z8000\z8000.cpp).
  . Zilog Z80180/Z8S180/Z80182 and Hitachi HD64180RP: Fixed some bugs found when bringing up the (MESS) Apple II RamFAST SCSI card. When starting a timer, use its reload value, not zero. Fixed DMA completion IRQs being silently dropped when IFF is clear. Check the right bit for the DMA1 interrupt's edge vs level trigger setting. Internal IRQs could be taken while another interrupt was in flight and completely hose the machine state. External IRQs were already properly gated. Debugging was assisted by Claude Opus 5 (z180\z180.cpp).
- SOUND
  . Creative Labs CT1745 SB16 Mixer: Make irq/dma select to be user defined (sound\ct1745.cpp)
  . GI SP0256 Narrator Speech Processor: Adjust divider to achieve 10kHz sample rate
  . ICS2115 WaveFront Synthesizer: Improved register 0x10 implementation. Minor revert volume envelope behaviour (previous improvement retains to comment). Fixed namings. Reference: https://github.com/MiSTer-devel/Arcade-IGSPGM_MiSTer (sound\ics2115.cpp).
  . PlayStation SPU: Use ram_device. Support 512k/1mb/2m/4m SPU RAM (sample code at https://github.com/smf-/nolibgs_hello_worlds_spuram. Fixed register/DMA endian issues. Implemented master volume, voice1&3 decoded data writing and write CD decoded data even if no CD/XA playing. Use a timer to trigger SPU IRQ at the correct time. Implemented first/second half decoded data flag in status register. Extend SPU register space to support channel volume reading. Fixed chon register reading and FM chaining. Removed unused non interpolating code as the SPU always interpolates. Update SPU repeat address register when hitting a loop start (sound generation needs an overhaul to make this work properly). Fixes Judge Dredd audio delay in cutscenes (ID 08914) (sound\spu.cpp).
  . RCA CDP1869 VIS
    . Fixed tone and white noise output. Fixes sound in (MESS) tmc600, comx35, pecom64 and the Cidelsa arcade machines (altair and destryer). Implemented by Claude Opus 5 and based on recordings from a real TMC600. Validated that the sound output matches the recordings nigh 100% (sound\cdp1869.cpp).
    . Improved video accuracy. Proper tone-on-tone palette. Partial updates on OUT 3. Wrap the refresh address counter at the maximum page memory size. Ignore CPU accesses to page and character memory during display time. Assisted by Claude Opus 5 and validated side-by-side with a real TMC600 (sound\cdp1869.cpp).
  . Sega PCM/Sega 315-5218 PCM: Fixed end address off-by-1 regression (sound\segapcm.cpp). Fixes broken engine sounds in Enduro Racer (ID 09512).
  . Seta ST0016 (Audio): Improved sound emulation. Linear interpolation between samples: Hardware shows none of the images a nearest-sample fetch produces (mayjinsn/mayjisn2 samples play at 5.6-16 kHz on the 62.5 kHz output). Non-linear (mu-law like, 3-bit exponent / 4-bit mantissa float) sample format, enabled by voice 7 register $1f bit 1: set by renju, srmp5, gostop, koikois, nratechu, dcrown; clear in mayjinsn, mayjisn2, speglsht, macs, jclub2. Matches the byte statistics of the sample banks and renju PCB footage. Exponential volume law (~6 dB per 8 steps, 0 = mute) instead of linear; fitted to mayjisn2/renju PCB footage. Assisted by Claude Fable 5 (sound\st0016.cpp).
  . Sound Interface: Open device at emu rate to avoid resampler drift and compare queue bytes against bytes in backpressure check (assisted by GLM-5.1; sound\sdl3_sound.cpp).
  . Yamaha SWP30 sound chip: Two register field width fixes in the streaming block. Mask the unknown pitch bit before the finetune clamp. The per-channel pitch register (slot 0x11) carries a 14-bit pitch plus a bit that the firmware sets for compressed samples (0x4000). pitch_w() stores the raw value, and the streaming step adds it to the LFO offset unmasked. Before the loop point that is harmless because the exponent/mantissa extraction only looks at bits 0-13. Once the loop point is crossed and finetune becomes active, the clamp if(pitch & 0x4000) pitch = 0x3fff; sees the stray bit and pins the pitch to its maximum for the rest of the note. Measured on mu2000 with a single C4 on the strings patch (the firmware writes 0x7e28): the note is at -5 cents for the first ~150 ms, then jumps to +544 cents and stays there. Masking the bit at the point of use keeps it at -5 cents throughout. The predicted jump for 0x7e28 is 2^(471/1024) = +552 cents. The register itself is still stored unmasked so pitch_r() returns what the firmware wrote. The loop size is 24 bits, not 26. update_loop_size() masks m_loop with 0x3ffffff, but the loop size field is 24 bits wide. Bits 24-30 are the finetune, which step() reads back as (m_loop >> 24) & 0x7f a few lines below. The two overlapping bits mean any sample with a finetune >= 4 gets a loop size tens of millions of samples long, so it never reaches the loop point and just keeps reading forward through the wave rom. Audible on mu2000 as a note wandering through unrelated instruments: the oboe patch at C4 has finetune 0 and loops correctly (loop = 0000007a, size 122), while the sample used from E4 up has loop = 07000057, so the 87-sample loop becomes 50331735 samples. Fixing the mask makes those notes hold a steady pitch and timbre for the whole note. Co-authored-by Claude Opus 5 and 5.1 (sound\swp30.cpp).
  . Yamaha YMF271 OPX
    . Rewrote the YMF271 (OPX) core. Replaces the MAME-derived core with a new one. The model follows recordings of real hardware (no chip was available for direct probing): FM: OPM-style operators (logsin/exp tables, envelope generator at fs/2 with rate key scaling, detune, per-slot LFO with AM/PM), all 16 4-op algorithms, the 2x2-op and 3-op+PCM sync modes, feedback and the non-sine waveforms. PCM: 8-bit and packed 12-bit samples, linear interpolation, Fs divider and loop/end handling with End flags per slot group. AccOn (saturating accumulation) and Ext En/Ext Out: The extended channels CH4-CH7 (EXT1/EXT2 pins) are exposed as stream outputs 4-7. Status register 0 exposes the End flags of slots 12/24/36 as documented; End flags are cleared when the status register is read (required by the Brave Blade sound driver's voice allocator). Timers, external memory access and the device interface are unchanged. Assisted by Claude Fable 5 (sound\ymf271.cpp).
    . Wave 6 passes the modulation input through as a 9-bit ramp. The linear waveform's modulation input (scaled by MUL, 0 = 1/2) wraps at 9 bits and is stretched by 64 on top of the half-scale DC level, so a modulated wave-6 carrier swings up to 2.5x the range of the other waveforms. Fixes the level of the hi-hat and of the hard-panned synth in the Raiden Fighters ROM update BGM. Fixes Viper Phase 1 title screen SFX and item collection SFX are incorrect (ID 04533) (sound\ymf271.cpp).
  . Yamaha YMF292-F SCSP: Implemented main to sound CPU interrupt. Use direct DIPAN/DISDL if no EFSDL available for EXTS input source. Fixed saturn Multiplayer Audio CD silent playback regression (sound\scsp.cpp).
- DEVICE
  . ATA/ATAPI
    . Set removable media bit, don't report GOOD to UNIT_READY if no disc is inserted, and reject DVD-ROM commands if we're a CD-ROM (ata\atapicdr.cpp).
    . Don't double-IRQ IDENTIFY PACKET DEVICE (ata\atapihle.cpp). Handle DEVICE_RESET (machine\atahle.cpp).
    . ATA: Removed mem_mask from ata bus handlers to match hardware. Added default_data() to abstract_ata_interface_device for specifying the default bus state when no devices are driving the bus. Converted ata_hle_device_base base class to a mixin called device_ata_hle_interface. Converted ata_mass_storage_device_base class to a mixin called device_ata_mass_storage_device_interface. Support LBA48. Support IDE_COMMAND_IDLE_IMMEDIATE. Removed IDE_COMMAND_DEVICE_RESET as it's only valid for ATAPI devices (bus\ata\*).
    . ATAPI: Support IDE_COMMAND_RECALIBRATE & IDE_COMMAND_IDLE_IMMEDIATE (ata\atapi*). ATAFLASH: Removed hack for supporting 8 bit compact flash cards. Added default values for CISTPL_MANFID & CISTPL_VERS_1 (pccard\ataflash.cpp). LOG: automatically dispatch to logerror() or device().logerror().
  . Atari AVG/DVG: Correct vector intensity scaling (see GitHub #15835) (video\avgdvg.cpp)
  . CXD85xxx/CXD86xxx GPU (PSX GPU): Use ram_device. Added support for setting the PAL & NTSC CRTC clock & set the device clock to half the system clock (video\psx.cpp).
  . CGA (ISA8 CGA - 4enlinea, ISA8_CGA_TETRISKR and Yamaha V6363 CMDC (on-board CGA ISA8)): M24 mode2 bit 0 enables the 400 line mode, it does not select graphics. Text versus graphics is still selected by bit 1 of the CGA mode control register, so software that leaves mode2 bit 0 set while in text mode had its text page fed to the 1bpp renderer and nothing was displayed. Moved (MESS) chameleon CGA into cga.cpp and correct the charram as it supports 16 rows. Initial chameleon palette support (isa\cga.cpp).
  . Clock: Removed timing checks in callback function (machine\clock.cpp)
  . DECO 55 / 56 / 74 / 141 Tilemap Generator: Fixed attempt to set zero scroll rows. If only one scroll row configured, don't right-shift it. Caused an assertion failure in debug builds (dataeast\deco16ic.cpp).
  . Flash ROM: Added Macronix 29LV320ETTI Flash (machine\intelfsh.cpp)
  . Floppy
    . Removed hardcoded DSDD format, handle SSDD, DSDD, DSHD and DSED (formats\hxcmfm_dsk.cpp).
    . Disable LOG_DESC verbose logging left enabled during development (machine\wd_fdc.cpp).
    . Defer commands issued while a write is still live and fixed DRQ/BUSY/INTRQ ordering on force interrupt. New commands are held (delay_cmd) until a live write's trailing CRC/postamble finishes, instead of corrupting the in-flight write. interrupt_start() now drops a still-pending DRQ when aborting a busy command, matching command_end()/drop_drq() ordering. live_run() checkpoints on write completion so a late CPU register poll can't roll back a session the floppy device already closed. track_w() no longer drops writes when track_buffer is already pending, since the C1571 relies on INC-style back-to-back writes. Fixes (MESS) Commodore 1571 and 1581 MFM disk operations. Assisted by Claude Opus 5 (machine\wd_fdc.cpp).
    . Added weak sector detection. Fixes (MESS) specpl2a and specpls3 can't load floppy images (ID 06957)(ID 07001) (formats\flopimg.cpp). Support ED disk images. Sum the raw cell times in 64 bits before packing any of them into the 32-bit cell words: for a dense enough track (e.g. ED-density, 400,000 cells at the default per-cell time of 1000) the running total can exceed floppy_image::TIME_MASK's 28-bit range well before the track is fully written, corrupting the type bits of every cell pushed past that point. Normalizing each position inline against the true grand total keeps every packed value within its final (always < 200,000,000) range from the start. Assisted by Claude Sonnet 5 (formats\flopimg.cpp). Fixed get_track_data_fm_pc dropping the last sector of every track. The loop runs "sector < sector_count", so a call with sector_count = N extracts sectors 1 to N-1 and never writes the slot for sector N, which is left with whatever the caller had in the buffer. Its MFM counterpart, get_track_data_mfm_pc_sectors, loops "sector <= end_sector" and does cover the last one, so the two helpers disagree about what sector_count means. Nothing in the tree calls get_track_data_fm_pc today, which is presumably why this has gone unnoticed. It bites as soon as a format uses it to save an FM medium: on an 8 inch IBM 3740 diskette, 77 tracks of 26 sectors, it silently loses sector 26 of every track. Also makes the induction variable int, matching the MFM version, rather than comparing an unsigned to the int parameter (formats\flopimg.cpp).
    . Added verbose message upon loading image (imagedev\floppy.cpp). Batch sequential flux writes. Replaced write_flux with streaming write interface. The batching performance benefit from the earlier write_flux optimization is preserved: Transitions accumulate in the floppy device and are written to the track representation only at flush points, avoiding repeated track vector edits during sequential writes such as formatting (imagedev\floppy.cpp). Fixed weak-bit reads (imagedev\floppy.cpp). 
    . Set weak flag for applicable sectors (formats\dsk_dsk.cpp). Standard double-density tracks were padded to 105000 cells instead of the 100000 a 300 rpm / 250 kbps track holds, so the disc spun ~4.75% fast and timing-sensitive loaders polling between bytes fell behind and dropped data. Size the track from its actual sector layout, keeping the extra cells only for layouts that need them (theatre europe on einstein). Assisted by GLM-5.1 (formats\dsk_dsk.cpp).
    . Cleared the FIFO and any stale transfer state from a previous command (machine\upd765.cpp). Deassert DRQ on terminal count and prevent FIFO handling from reasserting DRQ after the DMA transfer has completed. Fixes floppy format in ct486 which enables the FDC37C78 FIFO. Fixed formatting (machine\upd765.cpp). In non-dma mode msr bit 5 (execution phase) was asserted for the whole execution phase instead of only while a byte is actually available, so the loader's poll loop lost its per-byte handshake. Assisted by GLM-5.1. Fixes (MESS) cpc6128 [goody, goodys19] freezes after loading (ID 07804) (machine\upd765.cpp). Gate dskchg with motor enable when reading DIR. Fixes (MESS) OS/2 2.x fails to recognize disks during GUI install in ct486 (ID 05573) (machine\upd765.cpp). Added mtr0_cb line for motor-on status (used by CMD FD-4000 to overclock the CPU when accessing disks), implement the DP8473/PC8477 Set Track command and added the PC8477 NSC command to identify the chip (0x72 for PC8477A, 0x73 for PC8477B). Assisted by Claude Sonnet 5 (machine\upd765.cpp). st1 should be clear if drive not ready (verified on hardware), EXM should not be set at command start (verified on hardware), set EXM after sector found. Setting exm by !ST1_ND can't work for read track so just use a separate variable to indicate a byte transfer is in progress (machine\upd765.cpp).
    . Moved floppy sound into a separate file (sound\drivesound.cpp) and clean up imagedev\floppy.cpp/h. Fixed include guards and added floppy sound to tiny build (sound\drivesound.h). Don't spin up immediately. Approximate real-world spindle spin-up time, i.e. the delay between the motor being switched on and the drive actually picking up speed. Heavier 5.25"/8" mechanisms take noticeably longer to get going than the lighter 3"/3.5" ones. If the motor is switched off again before this time has elapsed, the spin-up sample is never started, so no sound is heard at all. Fixes incessant clicking on CMD FD-2000 disk ready polling. Assisted by Claude Sonnet 5 (sound\drivesound.cpp).
    . Support D1M/D2M/D4M disk images. Assisted by Claude Sonnet 5 and GPT-5.6 Sol (formats\d2m_dsk.cpp).
  . Hitachi HD44780 LCD Controller: Added parent rom reference (sed1278 and ks0066; video\hd44780.h)
  . Intel 8251 USART: TxEMPTY remains asserted while transmitting sync characters. Empty commit to restart workflow run (machine\i8251.cpp).
  . Keyboard: Fixed missing column select pullup (pc_kbd\pcat101.cpp)
  . Konami 054000 Protection: Updates: Fixed naming (use snake_case and lowercase variable names). Use multibyte.h for 24 bit value getter. Fixed logging and side effect checks (konami\k054000.cpp).
  . MagicEyes VRender0 SoC
    . Set screen to avoid fatal error when a terminal is active and added setter for external UART clock (machine\vrender0.cpp)
    . Implemented external UART clock and worked around problem with buffer space polling. Claude Opus 5 implementation (machine\vr0uart.cpp).
  . MOS 6522 VIA and Rockwell R65C22 VIA: Fixed T1/T2 free-run timers going backward after underflow instead of counting down and T2 reads lagging T1 by IFR_DELAY clocks. Fixes (MESS) Commodore 1526 VIA/RIOT self-test. Assisted by Claude Opus 5 (machine\6522via.cpp).
  . MOS 6530 MIOT: Fixed timer_start() off-by-one tick that fired the underflow interrupt one cycle too late (machine\mos6530.cpp).
  . Motorola MC6845 CRTC: Don't recompute parameters before device has started (video\mc6845.cpp)
  . NCR 5380 SCSI: Protected constructors with default arguments are a bug waiting to happen. Restore base-part self-reset interrupt (regressed by GitHub #15658). Make SCSI bus reset edge-triggered. The SCSI bus reset (chip reset + interrupt) is triggered by the /RST line transitioning to true, not by it merely being asserted. The previous code triggered on the level (icmd_w reset unconditionally on ASSERT RST; scsi_ctrl_changed on ctrl & S_RST), so a device asserting RST while another device already held it would reset and interrupt a second time. Claude Opus 4.8 assisted with datasheet analysis and implementation (machine\ncr5380.cpp).
  . NCR 53Cxx SCSI Controller: Register 0xe must read as 0 on 53C94/53C96. Fixed NCR53CF94/96 features enable bit and revision read back (machine\ncr53c90.cpp).
  . RAM: Convert RAM to slot device to fix limitation of only being able to configure ":ram" from the command line & not having a UI to select the size. RAM sizes are now shown in -listslots/-listdevices & show up as slots rather than ramoptions in -listxml. Slot options are built from set_extra_options()/set_default_size(), so drivers do not require mass changing yet. size()/mask() are valid after device_config_complete(), pointer() can be called before device_start(), so the ram_device does not need to start before the device it's providing ram for. The width of RAM can be set in the drivers, allowing endian issues in state saves to be correct (machine\ram.cpp). Replaced -ramsize in comments with -ram and removed -ramsize from the docs & updated minimaws (ram_device). Updated PSX ram_device consistency, options are currently combined from set_default_size() & set_extra_options() but the other updates duplicated them for easier overriding of the default in the driver (sony\psx.cpp).
  . S3 86c764/86c968: Hookup CR50. Fixed SVGA 8-bit mode enable for Cybervision64 (video\pc_vga_s3.cpp). 
  . Sega 315-5124 SMS1 VDP: Fixed regression in (MESS) Road Rash (Game Gear) after Z80 core changed (When trying to draw the title screen, the wrong part of the screen gets shifted and the game hangs) (ID 09493) (video\315_5124.cpp).
  . VGA: Clear buffer on each frame for SVGA modes. Avoid transitional artifacts for 320x240 modes (video\pc_vga.cpp).
  . Z80 CTC: Start the timer on a counter to timer mode change. A control word switching a channel from counter to timer mode without reset and without loading a new time constant left the channel dead: no timer was armed and trigger() no longer counted. The real chip retains the time constant and starts timing on the following clock cycle. Fixes cassette save on the (MESS) Luxor ABC 800/802, whose tape routine relies on this to switch the bit clock. Assisted by Claude Opus 5 (machine\z80ctc.cpp).
  . Z80 SCC Channel
    . Gate transmit FIFO full logging on LOGTX. Release External/Status Interrupt latch upon channel reset (machine\z80scc.cpp).
    . Re-Arm the transmit interrupt when a character is loaded. The "Reset Tx Int Pending" command (WR0 = 101) suppresses transmit interrupts "until after the next character has been loaded into the transmit buffer", but the disarm flag was only cleared at the end of the following tra_complete(). The transmit-buffer-empty interrupt for that very character was therefore swallowed, so a driver that writes the next character from its interrupt handler stopped after one byte. Whether it happened at all depended on the write landing while the shift register was still busy, which made it look intermittent (machine\z80scc.cpp).
    . Updated RR0 latch when Reset External/Status Interrupt command is given and another change is pending (machine\z80scc.cpp). Fixes (MESS) macplus mouse cursor gets dragged to nearest screen corner/edge during disk loading (ID 09539).
  . Z80 SIO
    . Clear RTS/DTR flags in WR5 on channel reset
    . Fixed interrupt, DMA and status handling. Implemented 8085 three-cycle CALL interrupt acknowledge. Use channel A WR2 for interrupt mode/vector selection. Fixed special receive condition vectoring. Implement WR2A DMA request modes and interrupt suppression. Correct RR0 /RTSB reporting on channel B. Latch external/status inputs until reset and retrigger changed conditions. Suppress reset-time modem control edges. Fixed transmitter interrupt/DMA reset inhibition. Correct CRC preset and sync/hunt state handling. Tighten channel reset and first-character receive interrupt behavior. Fixes (MESS) MikroMikko 1 and 2 MPSC tests. Checked drivers that use z80sio for keyboard input are still working. Assisted by Claude Opus 5 (machine\z80sio.cpp).
    . K68564 improvements: Derive mk68564_device directly from z80sio_device. Correct XMTCTL character-length mapping. Implemented internal loop mode. Implemented MK68564 specific interrupt pending, acknowledge and vector handling. Also reset m_tx_count when starting a transmission from an idle condition to avoid additional delays - this change affects all z80sio devices. GPT-5.6-SOL was used as a research and debugging tool (machine\z80sio.cpp).
  . Zilog Z80 DMA Controller: Propagate BAO only when changed. Fixes (MESS) abc1600 stack overflow on soft reset (machine\z80dma.cpp). Sample RDY at the end of the transfer cycle. z80dma decided whether to continue a burst or block in the same callback as the write, using an RDY value the deferred update had not applied yet. A destination that drops RDY while being written was never noticed and a second spurious byte was pushed at it, corrupting (MESS) abc1600 floppy writes. RDY now tracks the live pin and the continuation decision moves one clock later, into SEQ_TRANS1_SAMPLE_READY. End of block still releases the bus in the same clock and byte-at-a-time is unchanged. (MESS) specnext_dma follows the new state. zorba relied on that extra byte to fill its row buffer in time, which exposed an i8275 pacing bug: The burst space counts character clocks between DMA requests, so measure it from DRQ rather than DACK and do not insert one before the first request of a row. Debugged and implemented by Claude Opus 5 (machine\z80dma.cpp).
- 3do.cpp
  . Fixes to make things boot: Fixed disc status reporting. Made missing XBus devices issure an Abort exception. The non-prototype ALG arcade games both boot, but need lightgun and coin hookups, at least. Debugging and analysis of the 3DO Portfolio source tree assisted by Claude Fable 5 (misc\3do.cpp). Updated driver flags and reword QA header (misc\3do.cpp). Orbatak wants the ALG BIOS to boot. Retire now unused 3dobios romset. Hookup Orbatak inputs. Added base inputs to md23do and sht3do. Hookup player 2 pad by default (misc\3do.cpp).
  . RISC CPU: Completed the recent 26-bit mode work so this core is now the single source for pre-AArch64 ARM implementations. Also fixed LDM with a banked base in the list, necessary for RISC OS 3's FPEmulator (which was broken on the old core too, for a different reason). Fixed LDR/STR R15 handling in 26-bit mode, which tripped up the aa680 boot ROM. Claude Fable 5 assisted with planning, the mechanical refactoring of the drivers, and the generation of a "before and after" test suite (arm7\arm7.cpp).
  . 3DO DSPP: DSPP has traditional audio DSP one-shot-per-frame scheduling on Opera vs. free-running on M2 (dspp\dspp.cpp). Cleaned up frame timing vs icount and implemented AUDLOCK. Fixes DSPP mixing at roughly 39 kHz instead of 44.1. Claude Fable 5 assisted with debugging and verifying that FMV lengths in MAME now match YouTube reference videos (dspp\dspp.cpp).
  . Madam: Support for direct 1bpp coded, 2bpp coded and 8bpp uncoded (misc\3do_madam.cpp). Added CEL projector basis. Added uncoded 8bpp RLE and fixed unpacked 8bpp coded colors. Added Packed CEL 1bpp, 2bpp and 8bpp. Clear Packed buffer after drawing pixel. Implemented relative CEL source/plut addressing. CEL support for yoxy, ldsize, ldprs and ldpixc. Refine CEL timings. Added primary DF setting to alt multiply. Support for MULT 3x3 dot product and swap. Fixed 16bpp lrform=1 drawing. Implemented relative next pointer CEL addressing. Fixed CEL vcnt masking and packed bitstream for 1bpp and 2bpp. Mask woffset10 against 10 bits in packed CELs. Added PIXC Multiply Factor for 8bpp CELs. Added CEL skipx handling. Refactor CEL functions using u32 return values and a special flag for packed transparency. Implemented pover and make 8bpp alt multiply to select from P-mode (misc\3do_madam.cpp).
  . Clio: Fixed Clio resetting the ARM to drop into the disc verifier. Bump VINT1 rate to 60 Hz. Hookup DSPP noise register from host side (misc\3do_clio.cpp).
  . Promoted Orbatak (USA, prototype) to working
- actfancr.cpp: Fixed endianness. Removed obsolete comments. CPU is Little endian, so sprite RAM should be Little endian. Also use multibyte.h for 16 bit sprite RAM getter.
- aleck64.cpp: Fixed screen refresh rate regression (nintendo\n64_m.cpp)
- amiga.cpp (alg.cpp, arsystems.cpp, cubo.cpp, mquake.cpp and upscope.cpp)
  . Fixed potential OOB palette select for OCS/ECS. Improved INT2/INT6 processing. Connect CIA 1 PA0/PA1 to SP/CNT (amiga\amiga_m.cpp).
  . Defer copper vblank restart while copper DMA is disabled. Fixes amigaocs_flop:maglines intro. Assisted by GLM-5.1 (amiga\agnus_copper.cpp). Prevent deferred updates from overwriting COPJMP2. Fixes the "lc" tests of the vAmiga Test Suite. Directly write chipset registers instead of going through the CPU (amiga\agnus_copper.cpp).
  . CDTV:
    . Connect CDTV and A570 subcode signals. Hook up 6500/1 remote control input converter. This allows the front-panel buttons for Play/Stop/Prev/Next to work. CD+G playback works now (amiga\amiga.cpp).
    . Correct port C input and interrupt latch handling (machine\6525tpi.cpp).
    . Hook up serial connection between the LC6554 LCD CPU and the CR511B drive. Controls in CD+G now work as expected, as well as the track display on the VFD. GPT-5.6-SOL was used as a research and debugging tool (amiga/cdtv and lc6500\lc6554.cpp).
    . Improved INT2/INT6 processing. Fixes cdtv:snoopy booting (amiga\amiga_m.cpp).
    . CR-511-B CD-ROM drive: Added raw P-W subcode output. Implemented direct drive control by serial interface. Keep SCOR active even for data sectors. Fixes hang after playing video in cdtv:covgrlsp. Cancel pending data transfers on a new read. Fixes cdtv:pinoc (and likely more). Report an error for invalid audio tracks. Fixes cdtv:psychoki and cdtv:psychokia. Use a table based command dispatcher. Implemented commands 0x00, 0x06, 0x80 and 0x83. Support early execution of commands by toggling the cmd line. The cdtest tool now reports "Drive Passed". GPT-5.6-SOL was used as a research and debugging tool (machine\cr511b.cpp).
    . Keep floppy DMA engine running even with no drive attached, Allows CDTV to boot without floppy drives (amiga\amiga.cpp and amiga\paulafdc.cpp).
- aristmk5.cpp, belatra.cpp, ertictac.cpp and ssfindo.cpp
  . Acorn VIDC1x/ARM VIDC20: Added mixer_device, fixed regressed sound mixing. Disable timer if sound frequency is zero. Implemented external sound clksel and hook it up to 'Pang Pang Car'. Make drawing a bit more safe. Fixed Acorn VIDC1x sample playback to reduce severe aliasing by correctly sequencing the 8 "channels" and properly added the FIFO and fixed the MEMC-side code to fill said FIFO. Fixed digital serial audio on the vidc20/iomd. Fixed ssfindo sample rate and make spacing more consistent. Fixed some loose ends, particularly with VIDC20. Converted to device_mixer_interface and moved speaker hookup to clients. Fixes aristmk5 sound routing. Improved pixel clock refresh rate calculations (machine\acorn_vidc.cpp).
  . ARM 7500FE SoC: Various fixes towards a7000p -bios 2 boot. Moved interrupt actual hookup to client responsibility, tentatively collect all sources rather than just the active change. Use actual 2 MHz clock for timers, and fix live readbacks. Unconnect keyboards for Arcade targets. Start hooking external interrupts. Fire sound IRQ at the end of a given sound DMA. Added vidstart handling and fixed wrapping address. Fixes (MESS) RISC OS behaviour in F12 Desktop shell. Vidend also needs to be wrapped in 4096 segments (machine\arm_iomd.cpp).
- astrcorp.cpp: Added a List of some CGA missing games
- atlantis.cpp and midzeus.cpp
  . Rendering improvements. Fixed fast clear leaving depth buffer at nearest. Added untextured solid-color quad path. Clamp translucency factors to fix darkened cars. Wrap texel addressing within waveram. Fixes Mortal Kombat 4 access violates running a benchmark, with -str 80 -norc -nothrottle switches (ID 08615). Decode SGRAM fill color/depth per R5E bit 5. Assisted by Claude Opus 4.8 (video\zeus2.cpp).
  . midzeus.cpp: Allow TMS320 CLKSRC to set internal clock. The driver fakes the C3x on-chip timers and hardcoded the counter at 100ns, but every game programs CLKSRC, which clocks it from the internal clock at H1/2 = CLKIN/4 = 15MHz. This didn't bother The Grid or MK4, but broke Crusin' Exotica.
  . Derive the dot clock from the divider in reg 0x31, hook up render XOffset and report VCOUNT in unscaled lines. Fixes several issues with Skins Game (video\zeus2.cpp).
  . Improved depth and blending. Treat depth-min register as floor, not per-object bias. Depth-test the alpha textures the game asks to. Decode the blend factors in reg 0x40 (video\zeus2.cpp)
- bfm_cobra3.cpp
  . Hook up MC68340 DMA and correct board signals. Read multiplexed inputs from the connected byte lane, pass the video controller interrupt at its asserted polarity and connect the active-high SCSI request to the DMA controller's active-low DREQ input (bfm\bfm_cobra3.cpp).
  . Added preliminary MPEG audio decoder. Implemented the host data interface, active-low reset and request signals, and MPEG-1 Audio Layer II playback using MAME's existing MPEG audio decoder. Improved buffering, control and save-state handling. Map host registers individually. Use fixed-width REQ state. Streamline silent audio output (sound\tms320av110.cpp).
- cdi.cpp
  . Enhanced Front Display. The LCD display now has indicator lights. Previously these were erroneously displayed as an 8th digit. This maps the Play and Pause indicator lights on the front panel. Visible when using audio CDs. Fully wires up the LCD display. Map Mute Button (philips\cdi.cpp and philips\cdi220_lcd.cpp)
  . Fixed Opcode length and rename Flag. Adjusted handling of "Disable Input Polling" mode and renamed to "Debug Mode" (philips\cdislavehle.cpp). Added Test Plug. Allow access to a test menu by booting the console with the Test Plug set (philips\cdi.cpp and philips\cdislavehle.cpp).
  . Cleanup Reset. The reset function has duplicated code and is slightly out of sync. This merge corrects a few mismatches. This likely impacts no games. Also added RAM time to the cdimono2 (philips\cdi.cpp and machine\scc68070.cpp).
  . Play Music CDs. This added a small disc-type check to the CD-i Slave HLE. This allows it to recognize music CDs, which triggers the CD player mode. Fixed CDIC Audio Track Size (philips\cdislavehle.cpp).
- chihiro.cpp: Fixed crash regression (shared\xbox.cpp)
- cinemat.cpp: Fixed visible area typo. Fixed display regression (vector list should be cleared after each frame).
- cmmb.cpp: Promoted 'Centipede / Millipede / Missile Command (rev 1.03)' and 'Centipede / Millipede / Missile Command / Let's Go Bowling (rev 1.62)' to working. Grok 4.5 assisted with reverse-engineering and Claude Opus 5 assisted with a cleanup/refactor pass once everything worked.
- cobracom.cpp, ghostb.cpp, lastmisn.cpp, oscar.cpp and srdarwin.cpp
  . Split dec8.cpp driver for different hardware configurations (dataeast\cobracom.cpp, ghostb.cpp, lastmisn.cpp, oscar.cpp and srdarwin.cpp)

  . Fixed CV1000 video timings. See: https://github.com/buffis/cv1k_research/tree/main/Video_Timings for analysis incl logic analyzer images/raw data.
  . Hitachi SH7709S: Fixed up background cycle accounting and bank conflict checks. Fixed burst write penalty. Fixed precharge conflict timing to use banks. Adjust background cycle accounting. Fixed address used for writeback accounting. Timing fixes + icache sampling changes. Added full icache tracking compile option. Added a couple of extra comments about slowdown oddities that show up in some titles. Added critical word first handling. Fixup background cycle accounting. Fixup some tpc/writeback accounting Don't need to use m_precharge_remaining_cycles as it's a fixed cost we can calculate on the background elapsed cycles. Fixed critical word first handling. Fixed AMX decode table for sdram bank. Move WCR1 to background accounting. Model remaining cpu cycle waits. Added cache port contention handling. These old single port CPU caches with unified I+D cache fight with the pipeline that can have some extra stalls as cache hits are not always "free" anymore. Added a simple model for estimating these contentended cycles (sh\sh7709s.cpp).
  . Added nandflash r/w and sound write timing (cave\cv1k.cpp). Added nandflash ready delay timing (machine\nandflash.cpp). Also track penalties for EEPROM access. Use the game uncached area access addresses (cave\cv1k.cpp). Added blitter r/w access penalties. Steal bus cycles on blitter uploads (cave\cv1k_v.cpp).
- cyclemb.cpp and kingdrby.cpp: Normalize blue palette
- djmain.cpp: Passwords no longer include the control word that is part of the command
- dyna_dc4000.cpp
  . Added GFX emulation, inputs and hopper. Games appear to be mostly playable, but need extensive testing. Claude Opus 5 reverse-engineered the blitter.
  . Replaced bad dumped gfx rom in Cherry Master '92 (V1.2D)
- dynax.cpp and royalmah.cpp
  . Correct protection implementation for games based on TMP9* using the internal ROM. cafedoll, clone cafedollg and ougonhai now boot.

  . Correct GFX for Bao Qing Tian (TIC). Claude Opus 5 identified the issue.
- firebeat.cpp and twinkle.cpp: Added configuration register reads. Added IDE (preliminary, doesn't seem to work right in riscpc). Fix enable bit (CR0 bit 0 not 1). Fixed MIDI 2 clock select (CR4 bit 5 not CR5). Changed default value on IDE ports to match rpcemu-extended (machine\fdc37c665gt.cpp).
- gms.cpp: Dumped EEPROMs for sglc and sjms
- gstriker.cpp: Fixed interpretation of line table to use signed per-line and per-pixel steps. Fixes pitch in gstriker/vgoalsoc/twcup94. Debugging, mathletics and the explanation comment were assisted by Claude Fable 5.1 (vsystem\mb60553.cpp).
- hyprduel.cpp: Fixed input name via usage and naming in test mode
- itgambl3.cpp, menghong.cpp and sanremmg.cpp: Bugfixes to M16C disassembler found with an Apple PMU99 firmware binary. ADJNZ/SBJNZ weren't handling the imm4 field properly. ROT/SHA/SHL count is signed magnitude, not twos-complement. 32-bit register pairs were not printed correctly due to order-of-operations. BMCnd condition decoding was wrong. Long JCnd displacement is not signed. bit,base:16[SB] was not showing the bit number correctly. PUSHM register order was wrong. BNXOR was being called BXNOR. UND instruction was not decoded. dsp:16[An] / dsp:16[SB] were shown incorrectly. Grok 4.6 assisted verifying the divergences from the M16C Software manual (m16c\m16cdasm.cpp).
- karnov.cpp: Documentation updates. Correct some ROM labels for 64street, avspirit, phantasm and edf. Added in PCB locations as where missing for said sets. Updated a few comments. Changed comments in the ROM def area to C++-style. Added comment about interesting 64street set.
- lazercmd.cpp: Lower DAC volume
- mcr.cpp: Moved most public stuff to protected / private
- model3.cpp
  . Mask texture coordinates in get_texture(). Fixes crash due to out-of-bounds read (sega\model3_v.cpp).
  . Redumped bad IC17 ROM for 'Virtua Striker 2 '98 (Step 2.0)'
- namcos10.cpp: Decrypted three more games. Decrypted 'Knock Down 2001', 'Slot no Oujisama / Slot Prince' and 'Gegege no Kitaro Yokai Yokocho Matsuri de Battle Ja' games. GPT-5.6-SOL model used to build tool implementing known plaintext attack on encryption (namco\namcos10.cpp).
- namcos22.cpp
  . Removed some redundant m_poly->wait() calls in screen_update. Replaced render_triangle_fan usages with render_polygon & render_triangle. Use render_polygon rather than render_triangle_fan for rendering clipped quads (namco\namcos22_v.cpp).
  . Clip extents before calculating its parameters (video\poly.h). Fixed lighting when using shared normals (namco\namcos22_v.cpp).
- nexus3d.cpp: Misc notes
- pgm.cpp: Improved ICS2115 register 0x10 implementation. Minor revert volume envelope behaviour (previous improvement retains to comment) (sound\ics2115.cpp). Fixes kov and kovplus speech cuts out at the title screen (ID 09541).
- polepos.cpp: Added clock on POLEPOS_SOUND for bootlegs. Fixed missing engine sounds.
- policetr.cpp: Updated comments
- popobear.cpp: Added NVRAM to magkengo and qiwang
- pspikes.cpp: Fixed screen flip for Turbo Force and clone Aero Fighters (Taiwan / Japan, set 1). Replaced the hand-tuned flip constants with values measured from the games themselves. The vsystem_spr2 mirror constants (previously hardcoded 308/208, only correct for clone Aero Fighters (Taiwan / Japan, set 1)) become per-game configuration, and the mirror is now zoom-aware. Write all 512 rowscroll entries instead of 256 so the mirrored row indexes read by a flipped tilemap are initialized. Co-Authored by Claude Opus 5.
- royalpkr.cpp: Improved IRQ handling. Added ACRTC maps for the high and medium resolution. Preliminary inputs from research of the dumper. IRQs handling improvements and palette hook-up for low and medium res games and config/serial reversal (where not documented by the dumper) done with assistance of Claude Opus 5.
- seattle.cpp: Initialize register file and timer state at reset. Fixes intermittent failure to boot on some Atari games (machine\gt64xxx.cpp).
- stella8085.cpp: Don't instantiate devices that don't exist. That shouldn't have been merged in the first place.
- stv.cpp
  . Sega Saturn DCC

  . Sega Saturn System Control Unit
    . Convert interrupts to IRQ_CALLBACK_MEMBER. Rewrote timer 0/1 logic. Cleanup, use enums for interrupt sources and DMA operating modes. Initial implementation of a DMA orchestrator (fixes diehard and dnmtdeka have no sound - GitHub #15769) (sega\saturn_scu.cpp).
    . Operational changes: Treat DMA direct mode as burst, indirect as cycle steal. Gain back a bit of performance by setting DTACK changes at DMA starts and stops only. Set a flag on DMA buses origins, disallow same bus transfers. Groundwork for setting cycle penalties. Fixed pfght regression using DMA as fill. Attempt to fix irq status non-dword writes ((MESS) burningr*, no noticeable change) (sega\saturn_scu.cpp).
    . Added a more consistent delay between DMA wait and move ops. Fixes regressions in danchih, danchiq and (MESS) avg and dejig* (sega\saturn_scu.cpp) (ID 06270).
  . Sega SCUDSP
    . Rewrote DMA to use a timer and removed instant hack. Make sure to honor C-Bus transfer fixed adds rule with DMA. Fixes (MESS) mshvssf bad colors in main menu and gameplay (scudsp\scudsp.cpp).
    . Refine some DMA loose ends: C-Bus DMA reads actually can be either 0 or 4. B-Bus DMA reads are hardwired to +4. DMA CTx pointers actually increments on every transfer (scudsp\scudsp.cpp).
  . Sega Saturn VDP1
    . Avoid using vertical cell scroll with linezoom for now, avoid 'Batman Forever' The Riddler stage going 0% emulation speed (ID 07203) (sega\saturn.cpp).
    . Make sure sonicjamj (hash\saturn.xml) doesn't fail SCU DMAs to VDP2 back-to-backs for now (sega\saturn_scu.cpp and sega\saturn.cpp).
    . Fixed sprite window in interlaced mode. Fixes (MESS) amoudan GFXs in main menu and gameplay. Implemented VDP2 4bpp bitmap with zoom mode (sega\saturn.cpp).
    . Don't do sprite window if type is invalid. Fixes several empty dot cases and (MESS) saturnjp [kof96, kof97, samsho4]: VDP1 transparency issue with several games (ID 07508) (sega\saturn.cpp).
    . Fixed VDP1 GFX alignment with flipy + clip y. Fixes (MESS) draculax inverted castle map plus some enemies glitching out when on top of screen (sega\saturn.cpp).
  . Sega Saturn VDP2: Moved CRTC logic in a new VDP2 device. Make it generate blank signals (sega\saturn_vdp2.cpp).
  . Sega Saturn/ST-V CD Block HLE
    . Fixed regression with CD auto boots. Fixes (MESS) saturnjp [azelpanztai]: Special Function Code Select enable 0004 0000, contact MAMEdev (ID 04951). Reset pending playback parameters when issuing a disc seek command. Added logging for disc status changes. Yield commands until status changes are performed. Make it play along with seek rules. Fixes (MESS) jungrhyt crashing when repeating a stage (sega\saturn_cd_hle.cpp).
    . 0x61 and 0x63 commands needs to calculate proper sectofs/sectnum before checking for a possible rejection. Fixes (MESS) shadtusk crash at startup (sega\saturn_cd_hle.cpp).
    . Improved reset selector semantics (sega\saturn_cd_hle.cpp).
    . Better handling of no disc cases: Fixed regression where tray open/close will just hang the emulated machine. Make it play along with the recently added status changes. Reset tray status only during power-on not device_reset. Fixed #15884 (sega\saturn_cd_hle.cpp).
    . Execute command even if CD isn't inserted and fixed modem status readback regression. Read ADR in TOC properly. Fixed curfad filter rejection range (sega\saturn_cd_hle.cpp).
    . Read ADR in TOC properly. Fixed curfad filter rejection range. Read TOC sets DTREQ only, doesn't change drive status. Fixes (MESS) hisspach boot (sega\saturn_cd_hle.cpp).
    . Improved redbook track resume and restart. Avoid (MESS) dendego crash on title screen, make Multiplayer Audio CD playback a bit more solid. Make repeat to honor seek phase and fixed redbook range. Fixed repeat assertion failure. Removed dubious handling of get status command (sega\saturn_cd_hle.cpp).
  . Start converting IOGA to use 315-5649. Hook it up to standard stvbios. Hopper, critcrsh and mahjong panel variants TBD. Hookup inputs for fanzonem and wwshin. Removed magzun boot patches. Demoted wasafari to MACHINE_NOT_WORKING (no way to rotate crank input in-game). BREAKING CHANGE: magzun now just black screen out of removing said hacks.
  . Make stvbios to use a 6 button input def. Added a dump cart header debug facility (sega\stv.cpp).
  . Demoted 'Virtual Mahjong 2 - My Fair Lady (J 980608 V1.000)' to MACHINE_NOT_WORKING. Note: Don't think it ever worked, has random sync problems with SH-2 reading sound RAM.
  . Promoted colmns97, danchih and danchiq to working. Cleaned up various Saturn code and made relationship between headers, sources and classes less confusing.

- taito_l.cpp and tnzs.cpp: Lower cpu quantum a bit
- taitogn.cpp: Use logmacro.h (machine\rf5c296.cpp)
- vectrex.cpp: Fixed regression caused by vector list overflowing (miltonbradley\vectrex_v.cpp)
- 100&Medal Kazaaan!!: Dumped PIC16C621A microcontroller

- Check Man: Lower AY-3-8910 volume for clone Check Man (Japan)
- Cross Puzzle: Made it boot. Reversed by Claude Opus 5. Applied feedback. 
- Cruis'n Exotica: Rework dashboard layout to match the real cabinet. Added unlit radio button (layout\crusnexo.lay). Updated release date for the latest Cruis'n Exotica version according to a Midway service bulletin (https://arcarc.xmission.com/PDF_Misc/Midway Software Versions as of 02-12-2001.pdf). Correct DIP name.
- Dragon Gun: Added decrypt function for a future i750 implementation to pull bytes through plus a small self-test. Claude Fable 5.1 assisted with reverse-engineering of the decryption, including a Python proof-of-concept and GPT-6 Astra assisted with a Python i750 emulator that proved the decrypted results decode to correct video using dragngun's own program.
- Dynasty: Dumped gfx rom for Dynasty (1992, V5.1G)
- Enduro Racer: Fixed end address off-by-1 regression (sound\segapcm.cpp). Fixes broken engine sounds in Enduro Racer (ID 09512).
- Euro Bingo 7: Added PAT PLD and counters SEEPROM dumps
- F-1 Grand Prix: Implemented screen flip. The flip bit in gfxctrl was latched but never used. The ROZ layer is not flipped by the video chip at all: The game writes a mirrored 053936 transform matrix itself. Removed MACHINE_NO_COCKTAIL from the f1gp sets; f1gp2 keeps it (different video path, still not implemented). Co-Authored by Claude Opus 5.
- Fancy Bowling: Made the game boot. Claude Opus 5 identified and solved the boot problems (missing ident of the CF card, UART communication getting stuck and blocking boot).
- High Seas Havoc: Improved decryption and hooked up PIC and inputs. Game is playable. Claude Opus 5 did most of the reverse engineering.
- Il Galeone: Added PLD dump
- Johnny Nero Action Hero: NEC VR5500 has unique page mask and Config encodings vs. stock MIPS III. Fixing this allows jnero to write a correct display list instead of garbage (mips\mips3.cpp and mips3com.cpp).
- Jongputer: Use decryption PROM instead of XOR tables for clone VS Computer Mahjong, fixes at least the stuck sound (constant tone in-game after the mahjong tiles are laid down). PROM hook-up by Claude Opus 5.
- Lady Gum: Marked PLD (locked) as bad
- Loto-Play programming device: Z80 sets are devices for programming Loto-Plays, not Loto-Plays. Now "lotoplayzx" sets no longer are clones of "lotoplay", but of the new parent "lotoplayz". Also added a new MC68705 set and put the speaker to all sets that have one. Split the programming devices on a separate file.
- Mayjinsen 2: Demoted Mayjinsen 2 as MACHINE_IMPERFECT_GRAPHICS via missing tilemap scroll emulation. Reference video at https://youtu.be/mMEvKZM6mkk.
- Mahjong Shinkirou Deja Vu: Fixed CPIR infinitely looping (tlcs90\tlcs90.cpp). Fixes mjdejavu and clone mjdejav2 tiles in players hand are not sorted automatically when start the game (ID 00964).
- Maldaliza: Completed protection patches. Game boots with wrong inputs. Missing patches found by Claude Opus 5.
- Mortal Kombat (Yawdim bootleg, set 4), Pango Fun (Italy), PGM and Poker (Version 50.02 ICB, set 4): Dumped and verified PLDs
- Operation Wolf: Latch TC0060DCA volume writes, fixes Operation Wolf.
- Outfoxies: Fixed overdumped mask ROMs on Outfoxies. Tested with the right EPROM equivalents on real hardware (27c800 for SHAR and 27c400 for SHAS).
- Q*bert and Q*bert's Qubes: Fixed a sign error that can make the SC-01 F2 noise-injection filter unstable for valid internal ROM states (sound\votrax.cpp). Fixes sound cuts off in Q*bert and Q*bert's Qubes after a while and doesn't come back (except for the knocker) (ID 09521).
- P's Attack: Made the game boot. Claude Opus 5 reversed the PIC16C711 fake ready return. Hookup gun triggers.
- Pac-Carnival: Dumped/Verified PLDs
- Paperboy: Fixed factory reset EEPROM for calibrated controls
- Psychic Force 2012
  . Fixed intermitant fatalerror in pf2012 and (MESS) p5txla. The PCI core can call remap() before the device gets reset (machine\w83877tf.cpp).
  . Preliminary GUI drawing (aka "ROP") support, including hardware cursor (video\atirage.cpp).
- Push-Over: Fixed scrolling. The game is playable but needs a better layout. GPT-5.6-SOL was used as a research and debugging tool. TODO: Needs a proper layout. Various sections of the screen should be hidden behind an opaque screen overlay (https://youtu.be/rf1VuWgFDJ4).
- Raiden Fighters Jet: Clones rfjetsa and rfjet2kc speedup hack checks were missing, rfjets testmode workaround appears to be obsolete (entering testmode works fine).
- Ring & Ball: Made 'Ring & Ball (Italy, Ver. 2.6)' run. Claude Opus 5.0 identified the unusual split supervisor mode/user mode code encryption method.
- Robot Bowl: Dumped PROMs (line drawing; not used by the emulation)
- Scorpion: Fixed rom loading for clone Aracnis (bootleg of Scorpion on Moon Cresta hardware, set 2) and promoted game to working.
- Sea Wolf II: Fixed French language DIP switch
- Super Glob: Connect test switch to enable diagnostics for theglobp and similar epos games (beastfp, beastfpa, theglobp, theglobpa, theglobme, sprglobp, sprglobp2 and sprglbpg).
- Super Pinball Action: Fixed dipswitch port regression
- Syvalion: Fixed sprite vertical zoom and low life warning message in Syvalion. Analysis assisted with Cursor Grok 4.6 (taito\taito_h_v.cpp).
- Tao Taido: Fixed player 2 controls in clone Tao Taido (6 button version). Note: For a long time in clone taotaidoa, player 2's kick buttons (4-6) actually causes player 1 to kick in-game, as if they pressed their own corresponding kick buttons. The game checks player 3 and 4 inputs, which are visible in the service mode's input test program, and reuses them for kick buttons. As noted in the driver notes, players 3 and 4 aren't used at all in the 2-button parent taotaido or the 2/3-button clone taotaido3. Adjusting the 'P4' port to map buttons 1-3, rather than three of the directions, to player 2's buttons 4-6 allows player 2 to kick as expected.
- Tetris (set 1)
  . Update PCB layout. All components correctly identified and checked against a real PCB.
  . Correct ROM labels and added some PLD dumps to clone Tetris (bootleg set 6, with UM3482)
- Tong Zi Maque: Fleshed out the driver. Claude Opus 5 completed the decryption, reversed the EEPROM and RTC hook-up and helped with the GFX emulation.
- Wink: Emulated protection according to schematics. Reversed by Claude Opus 5.

- Fixed rom names in cbasebal.cpp, goldstar.cpp, megasys1.cpp and sbmjb.cpp
- Renamed (akamj) to (akamja), (cobracomjb) to (cobracomjbl), (dynamj) to (cll2), (ichiban) to (ichiban305), (karnova) to (karnov5u), (koikois) to (koikoisa), (srdarwinb) to (srdarwinjbl), (tabpkr) to (royalpkr185l), (wink) to (winkob) and (winka) to (wink).
- Dipswitch fixes in cmmb.cpp, crospuzl.cpp, dyna_dc4000.cpp, hshavoc.cpp, midzeus.cpp, pacman.cpp, simple_st0016.cpp and tomsadvs.cpp
- MAME
  . VIDEO RENDERING SYSTEM
    . Split the screen_device into multiple devices depending on the actual type. Scripts to do the mass conversions written by Qwen 3.6 (emu\divo.cpp + emu\screen_svg.cpp). Re-Add aspect ratio info (useful for determining driver screen 'resolution') (emu\screen_svg.cpp).
    . Changed the frame_period API to use attotime instead of attoseconds. Fixed the "default sizing" case (emu\screen.cpp).
    . Fixed a ~20 year old bug (dating to 0.106u2) with vector.cpp: The initial point of the first vector line when a new vector list was processed always started at 0,0 instead of starting at the end point of the last line in the most recently processed vector list (emu\vector.cpp).
    . BGFX: Added vector CRT renderer (GitHub #15692). Enable vector CRT rendering by default. Keep -nobgfx_vectorcrt available as an explicit opt-out. Increase bloom targets from one-third to half resolution to prevent the blur kernel from becoming under-resolved at 1080p. Normalize blur offsets against output resolution to preserve the apparent bloom size (bgfx\* and render\bgfx\*).
  . MEMORY SYSTEM: Fixed nullptr access during validation (emu\emumem_mview.cpp and emu\emumem.cpp)
  . LUA engine
    . Fixed null-pointer crash in emu.wait()/on_machine_postload() when called before the wait-task timer is attached (mame\luaengine.cpp).
    . Allow omitting the condition and action for bpset and wpset. Fixes LUA bpset/wpset functions cause MAME crash (ID 09543) (mame\luaengine_debug.cpp)
  . INPUT/OUTPUT
    . Actually added the rules to clean preset/example INI files (makefile)
    . Allow scripts to enumerate device outputs (emu\output.cpp and mame\luaengine.cpp).
    . Make state readable (machine\input_merger.h). Example usage: Reads interrupt state in atlus\cave.cpp and kaneko\sandscrp.cpp. Use input_merger_device::in_r for read IRQ state in isa\sb16.cpp and (MESS) pc98_cbus\sb16_ct2720.cpp.
    . Added missing Tab key mapping (emu\ioport.cpp)
  . UI/OSD
    . Clear transient UI BIOS option without preserving command-line priority. When returning to the internal UI, MAME currently clears OPTION_BIOS by setting it to an empty value at command-line priority. This preserves a high-priority empty BIOS option, preventing per-system INI files from setting the BIOS on the next launch when no BIOS menu is shown. Revert the command-line-priority BIOS option instead. This keeps the original intent of clearing transient UI BIOS selections, while allowing game/system INI BIOS settings to apply again on subsequent launches. Fixes GitHub #11313 and #11314 (frontend\mame\mame.cpp).
    . Better handling of "main menu" mode. Also cleaned up execute bits and stray BOM characters and added makefile rules to srcclean more files (ui\selmenu.cpp and ui\simpleselgame.cpp).
    . Set lowest possible HQ resampler latency to 0.1ms (0 latency broke sound for some games) (ui\audioeffects.cpp). Fixes no sound in all BallySente games, if the Resampler type is set to HQ with the latency of 0.0 ms (ID 09533).
  . NETWORK
    . Set PCAP_D_IN after open. BSD implementations of pcap (including macOS) echo your own frames back at you, which breaks MacTCP. Suppress it with PCAP_D_IN where available (netdev\pcap.cpp).
    . Fixed inverted success/failure return from send(). pcap_sendpacket() returns 0 on success and PCAP_ERROR on failure, but netdev_pcap::send() was returning the byte count only when the call failed and 0 on success. Removed orphaned dead comment in send() (netdev\pcap.cpp).
  . CHDMAN
    . Added parameter for add/remove pregap in createcd and extractcd (tools\chdman.cpp and util\cdrom.cpp). Changed LZMA compression level to keep the same dictionary size with updated LZMA SDK (util\chdcodec.cpp).
    . Added GDI pregap support (tools\chdman.cpp and util\cdrom.cpp)
    . Use modern C++ standard library facilities (#15889). This updates a few older parts of the CHD code to use standard C++ library features. Changes: Use .data() (C++11) when passing the start of a container. Use std::sort (C++98) instead of qsort. Use std::bit_width (C++20) instead of the custom bits_for_value function. Use std::endian (C++20) instead of manually checking the system's byte order. Checked the std::endian replacements against the old byte-order detection: The old native_endian == 0x100 check corresponds to big-endian and native_endian == 1 corresponds to little-endian. Added or removed includes as needed for these changes. * Use data() instead of &container[0]. Replaces &container[0] with container.data() where a pointer to the start of a standard library container is required. Uses that refer to an offset within a container are left unchanged. This makes the intent clearer and avoids indexing the first element just to obtain the underlying data pointer. No functional change intended. GPT-5.6 Sol (OpenAI) was used to help identify applicable instances and review the changes. Grok 4.5 was used as an additional code review. * Removed unused metadata_hash_compare function declaration. * Refactor sorting and remove unused comparison function. * Replaced qsort with std::sort for metadata hashes. Added operator< to metadata_hash and use std::sort instead of the C qsort + function pointer. Removed the now-unused metadata_hash_compare helper. * Removed cstdlib include from chd.cpp. Removed unnecessary inclusion of cstdlib header, no longer needed after removing qsort. * Make metadata hash comparison local to sort. Moved the metadata_hash comparison from operator< to a local std::sort lambda, keeping the comparison logic at the point where it is used. * Use data() for vector metadata input. Use vector::data() when passing the metadata input buffer, matching the same container access cleanup in chd.cpp. * Replaced bits_for_value with std::bit_width. Use the C++20 std::bit_width function instead of the custom bits_for_value implementation. * Removed static method bits_for_value from chd.h. Removed the now-unused bits_for_value declaration from chd.h after replacing the implementation with std::bit_width. * Fixed formatting of sort function for hasharray (util\chd.cpp). * Use data() for vector buffers. Use data() when passing the start of vector buffers. * Use std::endian for native byte order. Use std::endian instead of manually detecting native byte order (util\chdcodec.cpp). Use data() for vector buffers. Use data() when passing the start of vector buffers (tools\chdman.cpp).
    . Fixed several size and range handling issues: Check the full hunk byte-by-byte when determining whether it is zero-filled. The previous code checked the buffer as uint32_t values, which could leave the final 1-3 bytes unchecked when the hunk size was not divisible by four. Checking bytes also avoids requiring the input buffer to be aligned for uint32_t access. Used GPT 6.3 to help find what to change. Reject zero hunk and unit sizes before calculating the hunk and unit counts. This prevents division by zero when opening a malformed CHD. Reject zero hunk and unit sizes before checking the number of units per hunk. This prevents modulo by zero when creating a CHD with invalid size parameters. Treat zero-length byte reads and writes as no-ops. This avoids unsigned underflow when calculating the last affected hunk from offset + bytes - 1. Keep parent unit references in 64-bit values when compressing V5 maps. Also perform parent unit index calculations in 64-bit arithmetic to avoid truncation or overflow for references beyond the 32-bit range (util\chd.cpp). Retain session data (util\cdrom.cpp, util\chd.cpp and tools\chdman.cpp).
    . Fixed session parsing by extending the read_metadata function to include the absolute meta-index (util\chd.cpp and util\cdrom.cpp)
  . 3RDPARTY
    . Updated ASIO to version 1.38.2, Expat 2.8.3, GLM to 1.0.3, LSQLite3 to 0.9.7, Lua to 5.4.8, LZMA to 26.02, PUGIXML to 1.16, SQLite3 to 3.53.4, utf8proc to 2.11.3 and ZSTD to 1.5.7.
    . Revert MAME 0.289 "plugins/keypress: New plugin for recording player behaviour (#15379)". See mamedev/mame-goodies@d1c9005386b6af654e50d3d462d11743575c7418 for a better implementation of the concept.
  . UTILs
    . Added a function for converting system clock time points to NTFS timestamps (util\timeconv.cpp). Moved some PKZIP format constants to a header (util\pkzipdefs.h and util\unzip.cpp).
    . Added initial support for creating PKZIP archives (util\archiver.cpp). Added functions that take a reference to a stream rather than a smart pointer that don't take ownership. This makes it clearer than using core_file::open_proxy which doens't extend the lifetime anyway (util\chd.cpp, util\unzip.cpp and util\un7z.cpp). Added some error checks that had been overlooked (util\un7z.cpp and imagedev\diablo.cpp). Got rid of core_file dependency in a lot of places, use I/O interfaces instead. Stage the correct set of changes (util\chd.cpp).
    . Removed text writing functions (util\corefile.cpp and emu\fileio.cpp). Added an output stream buffer for writing text to a write_stream with line ending translation and/or transcoding to UTF-16 (util\ioprocsstream.cpp). Declare UTF-8 encoding in the XML declaration rather than the non-standard practice of prepending an encoded U+FEFF (util\xmlfile.cpp and mame\cheat.cpp). Fixed line ending translation not being applied for certain parts of the HTML output (tools\regrep.cpp).
  . Consolidate drivers into single file (sidearms.cpp and tceptor.cpp)
- MAC OS X: Revised macOS-native OSD. Not the default yet, but users and developers on macOS are encouraged to try it (build with OSD=mac). Supports soft (CoreGraphics), opengl, and bgfx video modes. Controllers are supported via both classic and auto-mapping/MFi providers. -video none does not bring up a visible window in order to facilitate more seamless automated and/or LLM-driven testing, but the menu bar and Dock "quit" methods still work if a -video none MAME gets away from you. Window resizing is kept aspect-ratio compliant when MAME -keepaspect is enabled. Supports multiple windows and multiple monitors, including using an iPad for Sidecar mode. Claude Opus 4.8 and 5 assisted with debugging, planning, and interpreting the more vague parts of Apple's documentation.
- Compiling
  . Updated Android builds to use SDL3. Use SDL_INSTALL_ROOT to get proper pkg-config settings and extract include too (osd/sdl3). Make build use OSD=sdl3 by default and fixed compilation. Updated gradle, sdk and java code to SDL3. Fixed sdk warnings (android). Should use pkg-config as others. Require only EMSDK and update docs (asmjs).
  . Attempted fix for Windows build related to gruesome header name collision (windows\window.cpp)
  . Removed #include "sound.h and "video.h" from emu\emu.h
  . Renamed osd\windows\video.cpp/h to osd\windows\winvideo.cpp/h to resolve header name collision 
  . Replaced eminline bit manipulation functions with C++20's  (formats\aiffile.cpp, formats\ap_dsk35.cpp, util\hashing.cpp and util\msdib.cpp). Retire rot[lr]_32 and rot[lr]_64 inline functions in favor of std::rot[lr] from C++20's  (osd\eminline.h).
  . Cleaned up various things, mostly where .c_str() is unnecessary (isa\isa.cpp, imagedev\harddriv.cpp, sound\disc_inp.hxx, emu\emuopts.cpp, emu\image.cpp and util\timeconv.cpp).
  . Fixed build with ZLIB_CONST defined (util\ioprocsfilter.cpp). Build libformats and libutils with ZLIB_CONST defined.
  . Use read/write stream interfaces rather than core_file where possible (emu\video.cpp)
- Debugger
  . GDB stub debugger (gdbstub)
    . Proper Z80 architecture support in the gdbstub. Assisted by GLM-5.1. REF: ttps://sourceware.org/git/\?p\=binutils-gdb.git\;a\=blob_plain\;f\=gdb/features/z80.c\;hb\=HEAD (debugger\debuggdbstub.cpp, z80\kc82.h, z80\z80.cpp and z80\z84c015.h).
    . Answer qOffsets so symbol files load unrelocated. GDB asks for the section offsets of the running target when a symbol file is loaded; without an answer it applies its default relocation and symbol addresses stop matching the emulated address space. The CPU address space is not relocated, so reply with all-zero offsets: a symbol file linked at its runtime addresses and loaded with "file"/"add-symbol-file" is used as-is. Assisted by GLM-5.1. Example (Z80, symbol file linked at its runtime addresses): (gdb) file boot.elf, (gdb) target remote 127.0.0.1:12000, 0x00000000 in ?? (), (gdb) break boot_continue and Breakpoint 1 at 0x69 (debugger\debuggdbstub.cpp). 
    . gdbstub socket lifecycle fixes: * Opening the listening socket at the first stop threw the fatal error from inside the instruction hook, crashing MAME with a segfault when the port was already taken. The socket is now bound in init_debugger and the fatal error is deferred to a reset notifier, which fires inside running_machine::run's exception handler and exits cleanly. * On detach the connection is closed once the reply has been flushed, so the port is free for another listener. Assisted by GLM-5.1 (debugger\debuggdbstub.cpp).
    . Expose all device state entries to the gdbstub. Generate target.xml dynamically from the live state entries instead of assuming the static per-arch register map matches, and append the visible state entries of all other devices (driver state, attached device registers) as mame. features, one register group per device named after its absolute path (the device tag with ':' mapped to '/'). The g/G/p/P packets are refused until the client has read the description so early probes cannot be misdecoded by regnum. Assisted by GLM-5.1 (debugger\debuggdbstub.cpp).

- New Clrmame: https://mamedev.emulab.it/clrmamepro/#downloads

- CPU
  . AM9517A: Refactor upd71071 based on v5x_dmau_device (machine\am9517a.cpp). A default argument value for a protected constructor is a bug waiting to happen, a default zero clock for a device_execute_interface is a bug waiting to happen (machine\am9517a.cpp).
  . Analog Devices ADSP-2100: Disassemble IDLE instruction (not emulated yet) (adsp2100\2100dasm.cpp)
  . Dynamic Re-Compiling
    . Fixed overflow flag calculation for ADDC. This is a case of GitHub #15043. SUBB doesn't seem to be affected (cpu\drcbec.cpp).
    . Better condition code calculation. Fixed issues with carry calculation for ADDC. Use constexpr templates for flag calculation rather than separate macros for 32-bit and 64-bit variants. Avoid conditionally evaluated expressions in carry calculation for ADDC/SUBB. Fixed dumb bug in zero flag calculation (cpu\drcbec.cpp).
    . Added support for invalidating code blocks in a specific logical address range without flushing the entire cache. This allows TLB/MMU page invalidations to do targeted generated-code flushes without the performance hit of flushing the entire DRC. PowerPC DRC changes which use this are currently being regression tested and will follow (cpu\drcbeut.cpp).
    . Invalidate up to the max length of a sequence prior to the starting address to catch sequences extending into the window. Not 100% ideal, but it performs well inside the constraints of the existing DRC data structures (devices\cpu\*).
  . MIPS-III: Fixed two issues with SC instruction: Fixed failure to store full sign extended result (GitHub #15730). Fixed behaviour when Rs and Rt are the same register. Fixed SCD when Rt and Rs are the same register (mips\mips3drc.cpp).
  . Ensoniq ES5510
    . When writing data to DOL, round towards zero. A bug report by sjs@sojusrecords.com identified residual noise when playing certain sounds on an SD-1 - specifically, the OMNIVERSE sound has a reverberating tail that goes to silence on a real SD-1, but retains a never-ending tail on an emulated SD-1. They investigated this further and found that this was consistent with a different, undocumented rounding difference when writing data to DRAM: whereas the documentation suggests a simple truncation of the internal 24-bit value to 16 bits, which is in effect rounding towards negative infinity, changing this to rounding towards zero eliminates the residual noise. Inline implies static linkage - no need for both. Also use constexpr (which implies inline) (es5510\es5510.cpp).
    . Round DOL towards -infinity after all. This partially reverts the functional change in https://github.com/mamedev/mame/pull/15527; but keeps the code and makes it a compile-time choice, for now, while this continuies to be investigated. It also keeps the changes that made DIL and DOL actually 16 bits wide. All based on investigation by @guilioz in https://github.com/mamedev/mame/pull/15527#issuecomment-4711323638 by @guilioz, which appears to show that the hardware ESP does _not_ round towards zero after all (es5510\es5510.cpp).
    . Fixed 'WRITE_REG{16}' macros. As identified by sjs@sojusrecords.com, the 'WRITE_REG' and 'WRITE_REG16' macros were not writing their 'x' parameter to a register as intended, but were instead writing the contents of the 'value' variable from calling code. Quite frequently this happened to be the correct thing to write, which hid the bug. Removed redundant #ifdef section; LOG_EXEC's use of LOGMASKED already handles the compile-time conditional logging (es5510\es5510.cpp).
  . Fujitsu Micro F2MC-16: External interrupts do not seem to have a iack/vector fetch cycle, according to the docs. And essentially none of the drivers use interrupts in the first place (f2mc16\f2mc16.cpp).
  . Hitachi H8
    . Formalize the contracts between H8 family peripherals and the CPU and interrupt controller so H8/500 can share. Fixed incorrect disassembly of SCB, PJSR, PJMP and TRAPA (h8500\h8500dasm.cpp). Preliminary H8/500 family execution core and peripherals. Based heavily on O. Galibert's H8/300 family work, and shares some peripherals. DTC (auto-DMA on IRQ) is not yet supported. Minor flag fix for disassembler. Emulate DADD instruction. Make DADD take cycles. Fixed Z flag calculation for DADD (h8500\h8500.cpp).
    . If an IRQ is pending when you enable it, fire the IRQ. (MESS) tg100 demo playback needs this (h8\h8_timer8.cpp).
    . Update active DMA channel on start/stop. Notify the H8 CPU when DMA channel active state changes so newly-started transfers are considered for execution. For H8H full address mode, restore completion behavior that clears DTCRA. This lets (MESS) Brother LW-840ic and LW-700i firmware observe DMA completion instead of polling indefinitely (h8\h8_dma.cpp) (ID 09456).
    . Added H8/3006 and H8/3007 refresh controller compare-match timer device.
  . Hitachi HD6309/E: Correct DIVD and DIVQ flag logic and cycle counts. Updated division algorithms to match hardware behavior verified by Fuzz6309 and XRoar. Fixed edge-case condition code handling for overflows and signed attributes. Implemented dynamic execution cycle adjustments using metrics discovered by hoglet67. Refined formatted and debugged implementation (m6809\hd6309.cpp).
  . Hitachi SH-2 (SH7604): DIVU OVF/OVFIE are full r/w flags (sh\sh7604.cpp)
  . IBM PowerPC
    . Bug fixes: * SPR[MQ] doesn't exist on non-IBM PowerPC 601, PCI Macs gets confused if it's present on IBM PowerPC 603/604. * TLBL: Compute both user and supervisor permissions. PCI Macs run the 68k emulator in user mode. * IBM PowerPC 603: PCI Macs look for processor version 0x00030001 for IBM PowerPC 603. Arcade games don't care. * IBM PowerPC 603: RFI unconditionally clears MSR[TGPR] on models with the TGPR mechanism. Verified against the IBM PowerPC 603 User's Manual and QEMU. * IBM PowerPC 603: BAT permission violations are supposed to raise DSI, not TLB miss. PCI Macs use this to trap and emulate accesses to NuBus-style I/O addresses (powerpc\ppc.h, ppccom.cpp, ppcdrc.cpp and ppcfe.cpp). Fixed lwarx/stwcx atomic loads/stores. Modernization pass: C comments to C++, some constants converted to constexpr (powerpc\ppc.h).
    . Updates: * Flags are now computed for all floating point instructions, which makes SANE much happier on the Mac. * The unique 601 decrementer is now fully supported, which allows pmac6100 to set the correct Gestalt ID. * Fixed a corner case in SRAWx where the destination register was not updated. * ICBI and ISYNC now end the DRC block and ICBI flushes the DRC code cache (may gate that on PPCDRC_COMPATIBLE_OPTIONS in the future). * More C to C++ style comment modernization and fixed some of the tab damage in the instruction commentary. * Tested on arm64 and x64 backends with a variety of games including scud, bujutsu, landhigh and gradius4.
    . Fixed uninitialised variable causing crash on start. Also fixed regression in lwarx ignoring reservation mask - looks like a bad merge.
    . Correctly swizzle physical address when reading instructions. The PowerPC recompiler currently swizzles the address on memory access, but the same swizzle must be performed on instruction access. This makes the relevant change in the frontend to honour the current little-endian mode state in the recompiler (powerpc\ppcdrc.cpp).
    . BxxL instructions need to set LR even if the branch is not taken. Allows Mac OS 9 to boot to Finder.
    . Make the forced DRC cache flush on ICBI optional, it was killing Mac OS 9 performance. Track at a 4K page granularity which logical pages have compiled code and flush only when necessary. Move UML-accessible variable into the DRC cache (cpu\powerpc).
    . When pages are invalidated with ICBI, only invalidate generated code on that page. For invalidate-everything cases, use a generation counter so that used blocks will recompile on their next call but unused ones won't (idea from OG's sound system). STRICT_VERIFY now does a byte-exact position-exact check. Some Mac OS self-modifying blocks were eluding the simple checksum. New option PPCDRC_STRICT_601_SELF_MODIFY enables monitoring writes to see if they hit a generated code block. Mac OS Sound Manager self-modifies without issuing ICBI (which is valid on 601 hardware due to the unified cache). This is a significant performance hit which is why it's optional. DRC code cache size bumped from 32 MiB to 128 MiB. The working set of Mac OS 9.1 idling in Finder was over 32 MiB so the cache was constantly thrashing. This greatly improves the stability of pmac6100 and makes Mac OS 9.1 fully usable (see my video of it running MacMAME full speed with sound from a network share). Regression tested against an assortment of Konami and Taito PowerPC-based arcade games (cpu\powerpc\*).
    . Fixed uninitialized variable that caused debug builds to crash (powerpc\ppccom.cpp)
  . IBM PowerPC 601
    . Two 601-specific fixes: 601 instruction MMU exceptions were being reported more like data exceptions, which caused the Power Mac 7200 to not import the Open Firmware device tree. The 601 real-time counter was always reading nanoseconds as zero due to unnecessary floating point usage (powerpc\ppccom.cpp and powerpc\ppcdrc.cpp).
    . Fixed 601 alignment exception reporting. Allows (MESS) Mac OS to properly emulate unaligned loads/stores (powerpc\ppc.h). The unique 601 decrementer is now fully supported, which allows pmac6100 to set the correct Gestalt ID. Push the correct ppccom.cpp with the 601 decrementer IRQ working (powerpc\ppccom.cpp). Fixed little endian mode selection in the 601. PowerPC 601 uses a bit in HID0 to enable little endian mode (powerpc\ppcdrc.cpp).
    . Fixed 601-specific corner cases in DIVWUx/DIVWUOx/DIVWx/DIVWOx [hardware testing thanks to DingusDev]. Fixed typo in 601-specific ABS/NABS that was causing incorrect decimal number printing (cpu\powerpc).
  . Intel 8086: Support port I/O wait states via access retry IN, OUT, INS and OUTS (including the 80186/80286 REP forms) now restart the bus cycle when a device signals a wait state through cpu_device::retry_access(), allowing ISA IOCHRDY to be modelled. Register and string-pointer updates are deferred until the access completes, so a stalled cycle has no side effects. No behavior change for devices that never request a retry (i86\i86.cpp).
  . Intel I386: Fixed copy paste error in fxsave (i386\pentops.hxx)
  . MC68307: Comment out line "reset_cb().append(*this, FUNC(m68307_cpu_device::reset_peripherals))" that doesn't work and wasn't tested. Note: All this does is cause an assertion failure on start. You can't configure a devcb after it's resolved. This obviously wasn't tested at all. Using a callback intended for stuff outside the device for things internal to the device isn't a good idea in the first place. This needs to be done properly.
  . Motorola MC68000/30/40
    . Update bftst to reluctant reads when fetching data from memory (m68000\m68k_in.lst and m68000\m68kops.cpp). Use std::countr_zero (m68000\m68000.h).
    . MMU fixes and updates: 68040 form of PTEST fixed and handled (previously didn't decode correctly). Fixed PFLUSH decoding so incorrect F-line traps don't occur. Indirect page descriptors write back U/M bits properly instead of potentially corrupting the page table. Reset now properly clears ITTx/DTTx. MMUSR now shown in the debugger to help track failed translations. PFLUSH on 68881/68030 now properly compare the ATC tag. Fixed typo causing misinterpretation of long-format descriptors. Indirect descriptors now are handled properly. PTEST on 68881/68030 properly handles levels shallower than the table depth. PMOVE to TTx now properly flushes the ATC. TC consistency check no longer throws exceptions on valid TC values with junk in the TI fields. MMU EA decoding now only accepts forms the real MMUs do. Added some guards against invalid page tables (m68000\m68k*).
    . Cycle counting overhauled for 68030 and 68040. Timings are significantly better but still inaccurate, especially on 68040 (m68000\m68k*).
    . The 68020+ bf* instructions all had a bug where they could trash the next byte in memory. Fixed disassembly of PMOVE. Consolidated handling of unimplemented coprocessor instructions (m68000\m68k*).
  . Motorola MC68881/2 + MC68040
    . Major FPU overhaul
    . FPU fixes and updates: FPU opcode now validated before doing any EA calculations. 68040-specific FSxxx/FDxxx instructions implemented. 68881 transcendentals implemented and verified.
  . National Semiconductor INS 8060 SC/MP II: Increment PC before opcode/argument fetches, not after (scmp\scmp.cpp).
  . NEC uPD7801: Fixed uPD7801 INT0 behavior (upd7810/upd7810.cpp and upd7810\upd7810_opcodes.cpp)
  . NEC uPD7807/C10/11: Rework HLT instruction behavior for upd7810 and variants (upd7810\upd7810.cpp)
  . NEC Vxx: Update carry and overflow after division based on observed HW behavior (nec\necinstr.hxx and nec\necmacro.h). Gate behaviour described in PR #15620 behind a setter for now (cpu\nec).
  . NEC V60/V70: Make irq ack cycle explicit through devcb (v60\v60.cpp)
  . PowerPC drc: Set function parameter when calling it. Setting the value when generating code won't work. Also, make the most of the smarter, templated UML_CALLC to eliminate many pointer casts (powerpc\ppcdrc.cpp).
  . SoundBlaster 16 Audio Adapter LLE: Concile with the new CT1741 DSP core (isa\sb16.cpp)
  . Texas Instruments TMS34010: Attempted to fix setcd for the case with two bits set. It was definitely wrong before - the mask to clear the first bit was calculated incorrectly.
  . Zilog Z80: Fixed minor hw discrepancy. Allowed 'Run to Next Interrupt on this CPU' not just for standard_irq but daisy as well (z80\z80.lst). Fixed NMI handling (RAMS' frogger works now) (z80\z80n.cpp).
  . Zilog Z8001/2: Changed address space for PSA reads, fixes interrupts not working. Added output callback for N/S state change. Fixed inc/dec versions of I/O instructions. Removed inc/dec lines for operands that shouldn't change. Made instruction names in comments and dasm consistent with official documentation. Fixed incorrect instruction ids in z8000_disassembler::disassemble. Fixed incorrect source read length in soutib/sotirb instruction (z8000\z8000.cpp). Added CPU status codes and is_ifetch1() (z8000\z8000.h). Made hack in RDMEM_W() more specific to the Olivetti M20/M40/M44. Enabled segmentation trap handling (z8000\z8000.cpp). Added initial Z8010 MMU implementation + segmented OS jumper and CPU board registers for (MESS) s8k. Clear DSC after changing SAR (machine\z8010.cpp). Made sure ldctl instruction in/out values are sanitized (z8000\z8000ops.hxx). Fixes for interrupts and stack handling. Read PC before changing FCW for all interrupts (z8000\z8000.cpp). Changed PUSH*()/POP*() functions to correct misaligned stack pointers (z8000\z8000ops.hxx). Fixed incorrect argument display for indexed cpb instruction (z8000\8000dasm.cpp). Inverted meaning of N/S state output. Changed the order of interrupt handling according to the manual. Fixed a typo (z8000\z8000.cpp). Fixed incorrectly displayed cpb and ldb instructions (z8000\8000dasm.cpp).
- SOUND
  . CEM3394 Synthesizer Voice
    . Incorporated va_vco oscillator implementation. Reduces aliasing. Correct some patches. Replaced CV dispatching function with multiple setter functions (sound\cem3394.cpp).
    . Removed no-longer-necessary stream updates. Moved route gain updates that only happen in one place out of update_mix(). Simplified pulse width computation. Removed on/off state for pulse waveform. Similar to the real hardware, the pulse waveform is always "on", but it effectively becomes 0 at both pulse-width extremes due to the pulse DC compensation (configured in 'device_add_mconfig()') (sound\cem3394.cpp).
  . Creative Labs CT1741 SB16 DSP Sound Unit: Convert CT1741 from ISA variant as standalone device
  . DECO 146 Protection: Made sound latch pending flag readable. Also suppress side effects for debugger reads and made some variables const (dataeast\deco146.cpp).
  . ICS2115 WaveFront Synthesizer: Changed volume behaviour to match hardware measurements. Reference: https://github.com/MiSTer-devel/Arcade-IGSPGM_MiSTer and https://github.com/laoo/PGMTech.
  . MIDI: Updated PortMidi to upstream version 2.0.8 (3rdparty\portmidi). Fixed discarded const qualifier errors (3rdparty\portmidi\pm_win\pmwin.c).
  . Sega 68k-based Digital Sound Board 2: Implemented ROM banking (sega\dsb2.cpp)
  . Sega PCM/Sega 315-5218 PCM: Split discrete logic variant and 315-5218 variant. Fixed output rate divider for both variants. Use struct for voice registers. Use address map to replace read/write handlers. Use shared_ptr for register storage (sound\segapcm.cpp).
  . Sound Interface: Fixed a deadlock on exit. coreaudio_stream::close() took m_stream_mutex before calling AUGraphStop. AUGraphStop blocks until the CoreAudio I/O thread finishes any in-flight sink_render callback, and that callback also takes m_stream_mutex -- so holding the mutex across AUGraphStop deadlocks: this thread waits for the callback to finish, the callback waits for the mutex. Stop the graph first (which quiesces the I/O thread, so no further callbacks fire), then take the mutex for the rest of the teardown (sound\coreaudio_sound.cpp).
  . Votrax SC-01: Fixed the noise injection filter (sound\votrax.cpp)
  . Yamaha YMF292-F SCSP
    . Added serial interface and hooked up MIDI input/output (sound\scsp.cpp). Send commands to the SCSP via the USART properly. Magical Truck Adventure now successfully reads "region check" code from SCSP (sega\model2.cpp and sega\model3.cpp).
    . Implemented MSLC delayed sample updates. Fixes vstriker repeated samples and srallyc played wrong sound keys at the end of the attract sequence (ID 09202) (sound\scsp.cpp).
    . Improved SDIR ("sound direct") emulation (sound\scsp.cpp)
- DEVICE
  . Cirrus Logic GD5401/GD5428/GD5430/GD5446: Fixed BitBLT transparent colour mask indices & update VRAM dynamic properties. Fixed BitBLT transparent colour mask register mapping. Update VRAM type handling. Fixed the id of GD5446. Update SR6 read handling (video\pc_vga_cirrus.cpp).
  . DECO 55 / 56 / 74 / 141 Tilemap Generator: Made tilemap register/config into structs. Fixed register usage and mark tilemap dirty behaviour. Made m_control an array rather than a very small memory share (dataeast\deco16ic.cpp).
  . DECO BAC06 Tilemap: Cleaned up code: Improved naming, reduced duplication and made some variables const. Removed a driver name comparison. Turned RAM areas into memory shares (dataeast\decbac06.cpp).
  . DECO RM-C3 PALETTE: Changed decrmc3 not to avoid ambiguity between clock and entries. Devices must expose a public standard signature constructor. All the verbs like -listxml, -validate, -romident, etc. assume it's available via device type objects, and bad things happen if it isn't (dataeast\decrmc3.cpp).
  . DSP563xx HI08 host interface: Forward DSP HTX writes to the host. htx_w only logged the outgoing word; it did not store it in m_htx or update m_isr. Host-side reads of HRX (offsets 5/6/7) therefore always returned zero and the host never saw ISR_RXDF asserted, so any 80C535 firmware polling HSR for a reply from the DSP after the bootstrap upload would spin forever. Store the word the DSP placed on HTX into m_htx, raise ISR_RXDF (which in turn asserts host-side HRDF and clears DSP-side HTDE through hsr_r's view), and let the host's read of the trigger byte at offset 7 clear ISR_RXDF so the DSP can transmit the next word. With this in place virusb boots all the way to its interactive UI: the LCD shows the patch / parameter pages and the panel buttons drive the menu (dsp563xx/hi08.cpp).
  . Floppy
    . Added missing header (formats\flopimg.h). Drop debug histogram dump that segfaults on small MFI. mfi_format::load() ended with a debug block that dumped a per-track cell-length histogram to stderr, walking a hard-coded 46-track x 2-side grid. get_buffer() only bounds-checks with assert (compiled out in release builds), so on an MFI smaller than 46 tracks or single-sided the loop indexes track_array past its end and segfaults. Removed the debug dump; load() now just returns once the tracks are in (formats\mfi_dsk.cpp).
    . Added save support (IMD write for flopconvert). IMD has been read-only in MAME's flopimg pipeline since 2017 - load() parses ImageDisk files, but flux-level images (MFI, captured floppies, running emulation state) cannot round-trip back to IMD. This change implements imd_format::save() so flopconvert and any future driver-side "save as IMD" path work in both directions for standard MFM and FM media. The save side decodes the flopimg flux representation per track, detects MFM vs FM and cell-size by scoring four common (encoding, cell_size) combinations (MFM @ 1000/2000 ns and FM @ 2000/4000 ns covering 250 and 500 kbps in both modes), then emits Dunfield IMD 1.20 records. Per-track detection handles mixed-density disks (e.g. CP/M boot disks with an FM 128-byte boot track on cyl 0 head 0 and MFM data tracks elsewhere) automatically. Use existing ccitt_crc16 function. Removed unused function (formats\imd_dsk.cpp) (GitHub #15385).
    . Fixed bad seek rate calculation with 4-phase steps as used with Apple II. Added direction feature to sound sample declarations (imagedev\floppy.cpp).
    . Make sure ST0 side bit it set to the last side actually accessed. Fixed formatting. Don't set side bit in st0 before a seek (machine\upd765.cpp). upd765 and derivatives: Fixed default DRQ behavior during write/scan. Standard uPD765-style FDCs should default to generating one DRQ per byte for write/scan commands rather than behaving like they have the 82072-style FIFO (machine\upd765.cpp).
    . Allow out-of-bounds track numbers to be passed to the sound routine for floppy_sound (imagedev\floppy.cpp)
    . Derive twosid_r() from media variant. Read media-sided-ness from the floppy_image variant tag rather than from observed track data via get_actual_geometry(). Drives sense single- vs double-sided media physically (e.g. 8" Shugart TS# on pin 30, from the index-hole position) so the answer must come from the media itself, not from whether the host happens to have written to head 1. An unformatted SSSD diskette is still single-sided. Before this change, twosid_r() reported TWO-SIDED to a host BIOS for any freshly-mounted unformatted media (heads==0 from get_actual_geometry returns false) and could permanently mis-report after a host wrote spurious noise to head 1 of a single-sided diskette. No call-site changes needed: all 17 twosid_r() callers and the uPD765 ST3 plumbing already do the right thing once this returns correctly. Fall back to geometry when variant is untagged. twosid_r() switched on the variant tag with default=two-sided, which relied on every format setting the variant. Formats that never call set_variant() leave it 0 and were silently reported two-sided. Treat variant 0 as 'unknown' and fall back to the previous get_actual_geometry() result, so untagged formats keep their old behaviour while tagged media get the deterministic answer (imagedev\floppy.cpp).
  . Hitachi HD44780 LCD Controller: Fixed char size selection in 2-line mode (video\hd44780.cpp) 
  . IDE Fixed Drive Adapter: Converted to remap FN (isa\ide.cpp)
  . Intel 8259 PIC
    . Don't clear interrupt requests when ICW1 is rewritten in level active mode and lines are active. Fixes (MESS) wangpc boot (machine\pic8259.cpp) (ID 09478).
    . Fixed OCW3 write behavior. Only set/clear RIS when RR=1. Only set/clear SMM when ESMM=1. Exit polling mode after one read cycle (machine\pic8259.cpp).
  . Keyboard: Added natural-keyboard control characters to generic_keyboard (machine\keyboard.cpp). Correct IBM PC/AT 84-key matrix positions. Added natural keyboard control characters (pc_kbd\pcat84.cpp).
  . MC68681 DUART
    . Fixed transmitter deadlock in tra_complete. The transmit-complete handler chose the next transmitter state from the TxRDY status bit rather than from whether another byte was queued in the THR. On a race between a CPU THR write and the final bit-time of the byte being shifted out, two cases could permanently wedge the transmitter: Completion with TxRDY set and a byte buffered took the "else" path, set TxEMT, and dropped the buffered byte. Completion with TxRDY clear and nothing buffered did nothing, leaving the transmitter idle with both TxRDY and TxEMT clear. In either case TxRDY never re-asserts and the transmit clock stays stopped, so a byte never drains and a polled transmitter spins forever waiting on TxRDY. Decide from the queue instead: load a buffered byte if one is present, otherwise mark the transmitter idle by setting both TxRDY (THR empty) and TxEMT (shift register empty). This is a no-op on the normal path, where tra_callback has already set TxRDY by the time completion is reached (machine\mc68681.cpp).
    . Assert TxRDY at the THR->shift transfer. GitHub PR #15564 cured a transmitter deadlock but asserted TxRDY (together with TxEMT) only in tra_complete's idle branch, i.e. at end-of-transmission. Per the SCN2681/MC68681 datasheet TxRDY is asserted at the THR->shift-register transfer, one full character time earlier, so firmware that pipelines on TxRDY (the Ensoniq VFX inter-board link and MIDI, e.g. sd132) saw the ready window a character time late and dropped bytes, tripping SYSTEM ERROR 144. Assert TxRDY in the reload branch where the queued THR byte transfers into the shift register; the idle branch sets TxEMT only. This keeps #15564's deadlock cure (TxRDY still re-asserts whenever a byte is queued) while restoring the correct one-character buffering window. Tested on sd132 (VFX) and pc532 System V (4x SCN2681 console) (machine\mc68681.cpp).
  . MOS 6522 VIA: Issue shift-out completion IRQ immediately when externally clocked. Matches the shift-in behavior and fixes unfavorable timing margins on PCI PowerMacs (machine\6522via.cpp).
  . Motorola MC6845 CRTC: The hpixels_per_column must be non-zero (GitHub #15625). A zero value causes implicit no setup in CRTC parameters, make it a mandatory parameter thru '-validate'. Other changes: Reorder device blocks. Removed empty device_reset trampolines. Mark register/data methods as virtual (CRTC-II and MOS8563 overrides them) (video\mc6845.cpp).
  . NAND Flash Memory: Removed sketchy NAND handling logic from gpl16250_soc and pump through the nandflash.cpp device instead. Added some NAND types needed for the JAKKS games etc. Added a few getters to nandflash.cpp so that we can manually get data out of the device for the existing bootstrap simulations now that a device is being used (machine\nandflash.cpp).
  . NB1413 Mahjong Custom: Fixed passing NB1413M3 variant as clock. This is the kind of regression that could have lurked for months and been a nightmare to track down. This is why you need to actually check your changes before committing.
  . NCR 5380 SCSI
    . Fixed pseudo-DMA initiator stalls and self-reset IRQ. Three fixes for ncr5380-family controllers driven as CPU pseudo-DMA initiators, found during pc532 (DP8490) bring-up: state_step(): a DMA wait state polling for a REQ/phase change returned no delay, so state_timer() re-armed at zero, freezing emulated time so the target could never change the bus. Poll at the SCSI REQ/ACK period (100 ns) from those wait states instead. scsi_ctrl_changed(): a bus phase change ends the DMA transfer and must deassert DRQ. Leaving it asserted with phase-match clear hangs drivers that poll (DRQ && !PHASEMATCH) for end of transfer. icmd_w(): a bus reset the host commands itself via ICR /RST must not raise a self-interrupt. device_reset() already deasserts IRQ, and the nscsi bus does not reflect a device's own /RST back to it, so only an externally-initiated reset interrupts (via scsi_ctrl_changed()) (machine\ncr5380.cpp).
    . Make ICR-issued SCSI reset interrupt chip-specific. A host-issued SCSI reset (writing the ICR ASSERT /RST bit) raises an interrupt on the base NCR5380/53C80: "SCSI reset RST is similar to a chip reset, but generates an interrupt", and the chip monitors /RST including the one it drives. The DP8490 EASI is the exception -- its ICR-issued reset performs the chip-reset actions, which "[do] not create an interrupt" (DP8490 datasheet 6.4 -> 6.2), unlike an externally applied reset (6.3), which does. Gate the self-reset interrupt on the device type so the base 53C80 interrupts while the DP8490 does not (machine\ncr5380.cpp).
    . Implemented target mode. Initiator DMA, data bus and reset fixes (machine\ncr5380.cpp).
  . S3 86C325/86C375/86C988 VGA core and SiS 6326 AGP/PCI card: Added PDxn ROP (pci\sis6326.cpp)
  . SCSI CD-ROM: Changed interpretation of play position slightly so games with redbook audio play it again (Apple SCSI; nscsi\cd.cpp)
  . SCSI Hard Disk: Move the opt-in seek-timing model into nscsi_harddisk_device. The cylinder-aware seek-timing model added to the Xebec S1410 and proposed for the DTC-510 was identical between the two controllers. Hoist it into their common base, nscsi_harddisk_device, so it is written once and is available to any hard-disk controller built on it without subclassing. set_seek_timing(), the model state, the fitted-exponent math (seek_time()) and a generic scsi_data_command_delay() now live in the base, which applies the model to the SCSI READ/WRITE/SEEK opcodes in both their 6-byte and 10-byte forms. The base default remains attotime::zero unless a driver calls set_seek_timing(), so every existing nscsi_harddisk user is unchanged. The legacy flat 85 ms per-command delay deliberately stays in s1410 and dtc510 -- it is a per-controller quirk, not a property of all hard disks -- so those two controllers are byte-for-byte unchanged with no model set, and delegate to the base only on the model branch (nscsi\hd.cpp, nscsi\dtc510.cpp and nscsi\s1410.cpp).
  . SCSI HLE
    . Deassert REQ between phases; hold BSY in COMMAND. scsi_change_phase() now deasserts REQ on entry, so the initiator sees a clean REQ low->high edge with the new phase's C/D-I/O lines settled. Previously the per-byte REQ-deassert timer was cancelled by the next phase's re-assert, leaving REQ continuously high across e.g. COMMAND->DATA-IN, so an initiator that samples the control lines on the REQ edge read the stale previous-phase C/D/I/O. A selected target also asserts BSY on entry to COMMAND, so a fast SEL deassert racing the sel_timer cannot leave BSY low during the connection (scsi\scsihle.cpp).
    . Allow targets to defer phase transitions. An nscsi_full_device target previously had to queue its entire phase sequence (data, status, message) before returning from scsi_command(), so a command involving slow media work had to complete synchronously. Make TARGET_NEXT_CONTROL hold the connection in the current state when the control queue is empty instead of popping an invalid entry, and resume stepping when scsi_data_in()/scsi_data_out()/scsi_status_complete() push new entries. A target can now return from scsi_command() with nothing queued, run the medium operation off a timer, and queue the data/status phases when it finishes. Targets that queue everything up front never reach the new path; no behavior change for existing devices (machine\nscsi_hle.cpp).
  . Slot device: Removed default zero clock for some slots that provide an input clock to cards where it's common to use the input clock to drive devices on the card. It should be possible to use DERIVED_CLOCK in these cards. A default zero clock will just encourage people to be lazy and not set the bus clock. Set the bus clocks for a few systems and added FIXME comments for others.
  . Z80 SIO: Fixed Rx interrupt logic (machine\z80sio.cpp)
  . Zilog Z80 DMA Controller: Fixed missing save state. Implemented DMA delay for (MESS) ZX Spectrum Next (allows to stop DMA in Continious mode for ISR) (machine\z80dma.cpp).
- 1942.cpp and vulgus.cpp: Added 2nd soundlatch. Spriteram is write-only. Added 16x256 sprite size. Improved bg scroll and sound for clone 1942 (bootleg on Vulgus hardware).

- astrcorp.cpp: Fixed a couple of GFX glitches
- atlantis.cpp and midzeus.cpp
  . Fixed Cruis'n Exotica road rendering. Fixed road/near-horizontal surfaces being culled. The "Fast HSR Removal" pre-cull tested only the view-space Z of the polygon normal, an orthographic facing test applied before the vertex transform. For near-horizontal surfaces such as the road, this sign flips and culls quads that actually face the camera, resulting in portions of the Cruis'n Exotica road being missing (video\zeus2.cpp).
  . Added near-plane clipping and perspective-correct texturing. Quads straddling the near plane were rejected outright, which dropped the nearest road segment in Cruis'n Exotica. Clip them against the near plane instead, as the Zeus 1 renderer does, keeping the visible portion. Textures were U/V interpolated linearly in screen space, which warped the geometry straddling the screen edge. Now carry U/Z, V/Z and 1/Z per-vertex and divide per-pixel so texturing is perspective-correct (video\zeus2.cpp).
- blockout.cpp, champbas.cpp, timeplt.cpp, tnzs.cpp (tnzs/tnzsj) and zerozone.cpp: The audiocpu/soundcpu runs in IM1, no need for set_input_line_and_vector.
- chihiro.cpp: Removed outdated workaround for missing library function (shared\xbox_nv2a.cpp)

  . Relicense as BSD-3. Make sound DMA non instant. Fixed potential irqs lost from SCSP to SH-1. Log cleanups. Hack around SH-1 clock to half speed (something is clearly amiss on this implementation).
  . Pull high serial reads for Aqua Stage and fixed call attendant messages
- cv1k.cpp: Added support for cache invalidation and entry writeback (sh\sh7709s.cpp). Map the cache address array to handle cache line flushing as well as writes to CCR that cause a cache invalidatation. Fixes the SDRAM region check as only area 3 is mapped to SDRAM on cv1k. Added basic uncached access handling as the instructions that execute to invalidate/flush cache lines have to be from an uncached region. Uncached access enablement and code cleanup. Enable uncached accesses and fixup missing case for uncached penalty. Added notes about cv1k slowdown. Address some review comments, moved register timing functions to member functions and moved some #define's to private static constexpr instead. Added some TODO's that need to be fixed and some timings that need verification (sh\sh7709s.cpp).
- dangbar.cpp: Split dangbar to own state and hookup Z80 LED CPU in there.
- gaelco3d.cpp: Use an exact reciprocal for zbase, rather than recip_approx(). On SSE2 builds, recip_approx uses the SSE rcpss approximation, which shifted texel sampling by ~1 pixel. Snap outer-edge verts to screen edge (gaelco\gaelco3d_v.cpp). Fixes some graphics in radikalb, surfplnt and surfplnt40 are differently aligned in 32bit and 64bit (ID 03342).
- goldnpkr.cpp: Decrypted Dash! (A37, ver 1998/10/22, Dynamic Chance (Type-3.0 Part 1-2), Lucky Full House (ver 1.16, data ver 1.05), 'unknown DEP 9801 poker game' and clones.

- igs009.cpp and spoker.cpp
  . Minor optimizations and cleanup: Restrict drawing to cliping rectangle. Suppress side effects for debugger reads, fixed some save state issues and improved logging. Reduced duplicated code and made some variables const.
  . Fixed igs009.cpp DIP switch input matrix. Note that jbell uses alternative hardware to other versions in description (different driver file).

- metro.cpp: Correct MSM6295 clock for Gun Master and Pururun
- model1.cpp
  . Fixed Virtua Fighter collision via TGP copro-RAM port model. The copro RAM data port (TGP side) had a bug that broke VF's collision pre-filter (op 0x63), causing skipped knockdowns and the characteristic "both fighters fall on one hit" double-knockdown. VF stores each vertex to check as 4 bytes (X/Y/Z/radius) and bits 16 & 17 of the address select the stride for the address auto-increment. VF is the only game that sets the stride to anything other than 1 so this is a no-op for the other games (sega\model1_m.cpp).
  . Removed "Arcade" and added manufacturer name to Star Wars title and correct year (April 27, 1994) (ID 06026)(ID 09462).
  . HUD layering, blink palette and wireframe fixes:
    . Tile palette bit15 = intensity/shade bit: The Model 1 tile palette top bit (bit15) is an intensity/shade bit, not an unused 'x' as the plain xBGR_555 decode assumes. Almost every entry has it set (full brightness); a handful clear it to render dimmed - e.g. the Star Wars Arcade menu backdrop pen (palette[0]=0x7777). Ignoring the bit left those pens too bright (the FIGHTER CONTROL backdrop rendered bright blue instead of the arcade's grey). Replace the COL region's plain palette_device::write16 with a handler that halves the channels when bit15 is clear. 0x7777 -> (94,111,119), matching the arcade; entries with bit15 set are unchanged.
    . Moire direct poly on transparent pen fades to backdrop: A Star Wars Arcade gunner 2nd-viewport overlay is a single moire (stipple-translucent) direct poly whose flat colour resolves to the transparent texture pen (index 0x1000 -> palette 0x8000 -> black). Painting the pen literally gives a hard black/scene checkerboard over the gunner; the arcade alternates backdrop/scene. Treat a moiré direct poly on the transparent pen as a "fade toward backdrop" overlay and paint the backdrop pen (0x400) so the stipple reads backdrop/scene/backdrop/scene. Scoped to push_direct (2D direct polys) so 3D object shadows are untouched.
    . Draw direct polys above the HUD tilemaps: The Star Wars Arcade FIGHTER CONTROL / cockpit screens put their callouts, pointer lines and viewport tints in direct (2D-projected) polys, which the hardware draws on top of the tilemap HUD. They were rendered interleaved with the 3D objects, so the indicators ended up buried under the HUD. Split tgp_render into two passes selected by render_pass: the first walks the display list drawing only the 3D objects (skipping the direct blocks), then the HUD tilemaps are composited, then a second pass walks the list again and draws only the direct polys, on top of everything. Display-list state (matrices, viewports, lighting, RAM uploads) is re-applied identically in both passes so the direct polys project with the correct viewport. push_direct previously guarded its vertex projection on z > 0 and snapped behind-"camera" vertices to (0,0). project_point_direct only offsets x/y by the viewport centre and ignores z, so that guard spawned huge spurious triangles radiating from the screen origin - harmless while buried under the HUD, but a bogus red cross over the SWA cockpit once the direct polys draw on top. Project every direct vertex unconditionally instead.
    . Tile colour mode field (blink, unlit UI elements): Bits [11:10] of the tile colour word select a colour mode. Bit 10 marks a flat UI element (radar blips, HUD text) that is drawn unlit at full intensity instead of being shaded by the scene lighting; mode 01 additionally blinks, rotating the BGR channels on alternate frames (the radar blips).
    . Rasterize degenerate quads as wireframe lines: Line primitives reach the rasterizer as a quad with two coincident vertex pairs. Drawing them with the scanline filler collapses near-horizontal wires to a few pixels, so detect that case and draw a proper line instead (e.g. the Star Wars Arcade target box).
    . Draw 0x41 objects above the HUD with a stencil: Reorganise rendering into a below-HUD pass (0x01 objects and 0x02 direct polys, sharing the per-viewport z-sort) and an above-HUD pass for the 0x41 objects such as the Star Wars Arcade radar blips. The hardware only lets the above-HUD objects show through "background" HUD pixels, so the HUD is snapshotted before the pass and its bright features restored over the result.
    . Invert moire checkerboard parity: Draw the moiré dither on the opposite pixels in both the scanline filler and the wireframe line, matching the hardware pattern.
    . Iterate overlay stencil by scanline within cliprect: Walk the snapshot/restore buffers with row pointers over the cliprect instead of a flat loop with a divide and modulo per pixel, and name the near-black threshold.
    . Fixes radar does not function in swa and clone swaj (ID 07699).
  . Repair 2-bit corruption in 315-5711 TGP copro ROM (Sega NetMerc, Star Wars and Wing War) (GitHub #15649) (ID 07563). Wing War's machine gun now registers damage correctly after this fix. The findings of these bugs were done with the assistance of Claude Opus 4.8 while doing HLE reversing of the TGP rom for Geometrizer, and the adaptation to MAME was done via local Qwen 3.6 27B.
  . Improved video and timer emulation. Improved lightbanks, backdrop and specular highlights. Implemented GLUE interrupt mask register. Set p1 = p0 for type == 2 (triangle) degenerate polygons in push_object. Inject initial NetMerc head tracker orientation on reset. Persist the zmode-0 flat-z register across objects in a DL walk. Use UART ready flags for IRQ3. Implemented programmable timer for IRQ0, assuming similar behavior to System 32. Select light parameter bank per polygon via flags bit 22. Implemented specular lighting, gated by the GEO mode word (sega\model1_v.cpp). Fixes netmerc segmentation fault (ID 06600).
  . Clip wireframe lines to the viewport: The wireframe rasterizer walked its Bresenham from raw projected coordinates. Those come from the unclipped projection, and a degenerate projection (z ~ 0 with the boot-time zoom still 0) yields inf/NaN, whose float->int conversion is undefined behaviour: x86 hosts get INT32_MIN where arm64 saturates and maps NaN to 0. wingwar generates such vertices while booting, and on x86 the resulting (INT32_MIN, INT32_MIN) pairs matched the two-distinct-vertices wireframe case and walked a ~2^31-pixel line with overflowing error terms - the gray screen boot lockup reported against GitHub PR #15597 (Windows only, and only when the below-HUD pass draws, since the above-HUD pass pushes no geometry there). Before that rasterizer existed these quads went through the scanline filler, which fill_slope()/fill_line() clamp to the viewport, so the same garbage stayed harmless and bounded. Give the line rasterizer the same property: Liang-Barsky clip the segment to the viewport before walking it. In-view lines are untouched; wires that used to leak a few pixels past the viewport edge now stop at it like every other primitive. Attract snapshots of vf, vr, vformula, swa, wingwar and netmerc are pixel-identical to master apart from one such leak. Verified against the boot hang by mimicking x86 conversion semantics on ARM64: Hangs before, completes after (sega\model1_v.cpp).
  . Return the latched count when reading a stopped timer (fixes Virtua Fighter hair physics regression from #15642) (sega\model1.cpp). Don't set palette format when palette write handlers shouldn't be used.
  . Skip degenerate moire direct polygons. Wing War's display list carries a constant record with all four vertices on one point; the flat-quad filler painted it as a stray dot at the viewport centre (sega\model1_v.cpp).
- model2.cpp and model3.cpp
  . Send commands to the SCSP via the USART properly. Magical Truck Adventure now successfully reads "region check" code from SCSP. Got rid of a trampoline for UART reads. There's still a hacky UART write handler.
  . Implemented MSLC delayed sample updates (sound\scsp.cpp). Fixes vstriker repeated samples and srallyc played wrong sound keys at the end of the attract sequence (ID 09202).
- namcos22.cpp: Revert "OR texture color with high bits of cz_adjust (namco\namcos22_v.cpp)" from MAME 0.288, fixes when the finish line track is visible from afar in Alpine Racer and clones, it initially appears as completely red polygons (ID 09466). Use clear_all_dirty for predecode gfxs (namco\namcos22_v.cpp).
- namcos23.cpp: Added unemulated camera flag to games that use the namcoss23_gmen_state class (ID 06586)
- nemesis.cpp
  . Added bs_ prefix to bubsys games. Group bubsys mcfg with the other mcfgs.
  . Cleaned up machine configuration and improved address maps. Hooked up add-on board for bs_rf2. Correct address mapping: In Bubble system and its ROM based conversion hardwares, RAM mapped to 0x70000-0x73fff is optional (via add-on board), and used and needed in gradius only. GX561 board has no RAM at '0x060000-0x067fff' and (bs_)rf2 doesn't used that area. Promoted bs_rf2 to working with unemulated protection. Made ROM region sizes match mapped sizes. Improved logging, reduced duplication and made some variables const. Added part numbers for add-on boards. Add-on board reference to Gradius (https://aucview.aucfan.com/yahoo/f242702941/) and rf2 (https://auctions.yahoo.co.jp/jp/auction/r1125298651).
- neoprint.cpp: Moved driver into snk folder. Hook up NEO-ZMC (machine\neo_zmc.cpp). Reduced literal tag usages and runtime tag lookups. Fixed naming and spacing. Suppress side effects for debugger read. Make some variables constant.
- novadesitec_fr002.cpp: External interrupts do not seem to have a iack/vector fetch cycle, according to the docs. And essentially none of the drivers use interrupts in the first place (f2mc16\f2mc16.cpp).
- pgm.cpp
  . Minor modernize and cleanups: Removed hardcoded tags and reduced duplication. Made data members private and some variables constant. Use a callback to read source data (igs\igs025.cpp and igs\igs028.cpp). Fixed argument in function (igs\pgmprot_orlegend.h). Fixed ROM data bus width (8 bit data bus) (igs\igs022.cpp and igs\igs028.cpp).
  . Marked 'Dragon World II' and clones as MACHINE_NOT_WORKING. Hangs due to incomplete protection simulation (see GitHub #15659)
- pgm2.cpp: Added some notes and correct a couple of decryption keys (igs\igs036crypt.cpp)
- popobear.cpp
  . Added IRQ enable. Fixes problem with magkengo RAM test on boot.
  . Ported over pixmap emulation from other bmc drivers. Used for test menus and other diagnostic messages. Added DIP banking. Improved inputs for qiwang and magkengo. Added qiwang input names from test mode in comments.
  . Tried to abstract tile emulation so it isn't completely hardcoded to what popobear does (still incomplete for tiles, still needs doing for sprites).
  . Separated memory map for magkengo and clone and reversed protection, they now boot. Improved sprite rendering. Support different height tilemaps + rowscroll modes on other layers (fixes qiwang piece display, popo bear ending).
- pspikes_ms.cpp: Fleshed out driver a bit. TODO: Tilemap colors and sound.
- rallyx.cpp: Replaced BANG sample with netlist (GitHub #15424). Removed the sample from rallyx and replace it with a netlist. The circuit was traced from the service manual directly, and only one component had to be added: MB3730_SIL. For this opamp, I tried to match as best as possible the datasheet. Output audio is very similar to the sample, but not equal, the sample may have some filtering due to the acoustics of the cabinet. Reduced noise and use unified amplification. Changed the MB3730 model to expose a parameter GAIN, whose default is the datasheet typical value. On rallyx, decrease the gain of the BANG source to reduce the noise floor, and inject the WSG audio using R28/C28, as in the original circuit (namco\nl_rallyx.cpp).
- raiden2.cpp: Fixed the bird dumbass (zeroteam; seibu\seibucop.cpp)
- segas32.cpp: Convert to using an irq ack method
- segaxbd.cpp: Updated comments
- ssfindo.cpp: Removed #if 0 in favor of LOG() and an if (0) and a use of ->pc() in logging in favor of machine().describe_context().
- stella8085.cpp: Fixed 4040 board IO (#15382). Added 4040 board IO map. Replaced DIY IO70 with proper 8255 PPI. Replaced device tags. Removed io73.
- stv.cpp: Extend mirror ranges of registers (sega\saturn_cd_hle.cpp). Added some notes (sega\smpc.cpp).
- subsino_kr_h8.cpp: Hookup RAMDAC and placeholder SG001 devices. Added gfx decode 4bpp format. Flesh out I/O ports a little and hook up DS2430A.
- taitojc.cpp: Major FPU overhaul. This fixes glitched polygons in TaitoJC games
- vp101.cpp: Separated slash in manufacturer names with spaces
- zaccaria.cpp: Added bruteforced PLDs to Money Money (set 3). Added placeholders for PLDs and 82s100 PROMs on every set (same PCB for both games). Load from 0x0000. Fixed note about PLD at 1a on ROM board.
- zr107.cpp: Refactored out common address map. Added TODO for area where Midnight Run EAC tests SRAM. Got rid of I/O ports that just obfuscate things.
- 720 Degrees: Fixed factory reset EEPROM (see broken hiscore table). Set initial joystick angle to 90.
- Aero Fighters: Fixed and added notes about sprite delay. Made sprite RAM double-buffered and delaying sprites by one frame.
- AGEMAME
  . Updated reel outputs in layouts (jpm\jpmsru.cpp).
  . Bulk updated remaining slot machine layouts that use yscroll for reel scroll (barcrest\mpu1.cpp).
  . Removed some unnecessarily added :pos from some layouts. Only the output names changed, the element names don't need to change (aces1.cpp, bfm_sc1.cpp, bfm_sc2.cpp, jpmimpctsw.cpp, jpmmps.cpp, jpms80.cpp, jpmsys5sw.cpp, maygay1bsw.cpp, mpu3.cpp, mpu4empire.cpp, mpu4mod2sw.cpp, mpu4mod4oki.cpp, mpu4mod4yam.cpp, mpu4unsorted.cpp and mpu5sw.cpp).
  . Made reel tags match layouts (aces1.cpp, bfm_sc1.cpp, bfm_sc2.cpp, bfm_sc4.h, bfmsys85.cpp, ecoinf2.cpp, ecoinf3.cpp, ecoinfr.cpp, jpmimpct.h, jpmsru.cpp, jpmsys5.h, mpu1.cpp, mpu3.cpp, mpu4.h)
  . Use same default local output name as machine\steppers.cpp (machine\em_reel.cpp). Also removed many superfluous :pos from layouts.
  . Replaced most of the remaining deprecated reel components in slot machine layouts.
  . Replaced more deprecated reel components in layouts. With the exception of m4gambal.lay, these were all impossible configurations, with more symbols visible than there are on a reel. I put in arbitrary numbers of symbols so they show something, but they're definitely wrong.
  . Manually patched up bad geometry and alignment in layout\j6bnkrcl.lay
  . Removed unnecessary set_periodic_int call (bfm\bfm_ad5.cpp)
  . Use clear_all_dirty for predecode gfxs (aristocrat\aristmk4.cpp)
  . Fixed MEMC access and hookup il0 for COMM ports 4-7. On this implementation MEMC register writes are by actual offset not data written. Fixed sound in dimtouch and others. Without COMM port irqs some games like qnile will hang after a number of played spins (acorn\aristmk5.cpp).

- Data East (actfancr.cpp, backfire.cpp, captaven.cpp, darkseal.cpp, dblewing.cpp, dec8.cpp, dragngun.cpp, dreambal.cpp, fghthist.cpp, hvysmsh.cpp, mirage.cpp, simpl156.cpp, sshangha.cpp and vaportra.cpp)
  . Split deco32.cpp driver into captaven.cpp, dragngun.cpp and fghthist.cpp/h due to hardware differences. Changed deco156.cpp driver to hvysmsh.cpp.
  . Fixed naming of machine configuration related name of fghthist and clones
  . Split hvysmsh.cpp driver state via hardware configurations. Fixed namings. Reduced duplicates. Fixed metadata via in-game version information screen and title screen. Fixed notes for version information screen.
  . Fixed backfire.cpp, hvysmsh.cpp and simpl156.cpp bitmap fill behaviour (restricted into cliprect).
  . Use sound latch pending flag from ioprot device in captaven.cpp and dblewing.cpp (dataeast\deco104.cpp, dataeast\deco146.cpp)
  . Fixed backfire.cpp speaker configurations (each screen paired with mono speaker).
  . Fixed dreambal.cpp notes (tilemap generator is 141). Reduced mirage.cpp unnecessary memory region. Fixed sshangha.cpp logging.
  . Fixed naming conflict with palette and palette RAM in darkseal.cpp and vaportra.cpp
  . Made some variables const in actfancr.cpp
  . Suppress side effects for debugger reads and reduced literal tag usage in dec8.cpp

- Donkey Kong / Donkey Kong Jr / Mario Bros: De-skeletonized 'Donkey Kong / Donkey Kong Jr / Mario Bros'. Added support for the 'AMD 29LV160DT Flash' (machine\intelfsh.cpp). Claude Fable 5 helped reverse-engineered the blitter. Promoted game to working.
- Double Dribble: Implement sprite X wraparound. Fold the 9-bit X to signed before drawing to reproduce an hardware wrap. Verified against video of original hardware: https://www.youtube.com/watch?v=aPylbn7BC28. Sprites exit the left side smoothly instead of disappearing abruptly when approaching the left side (GitHub #15661).
- Mahjong Dunhuang: Used hopper_device. Improved inputs a bit. Also cleaned up some random stuff.
- Filetto: Added diplocations and (unused) second DIP bank
- Flash Beats: Added layout and promoted system to working. Added H8/3007 refresh controller compare-match timer device (h8\h8_refresh.cpp). Improved SDIR ("sound direct") emulation (sound\scsp.cpp). Implemented ROM banking (sega\dsb2.cpp).
- Flicker (prototype): Outputs still need to be resolved manually

- Konami: Z80 based audio CPUs all runs in IM1, no need for set_input_line_and_vector (battlnts.cpp, circusc.cpp, combatsc.cpp, gradius3.cpp, gyruss.cpp, ironhors.cpp, junofrst.cpp, mainevt.cpp, mikie.cpp, pandoras.cpp, parodius.cpp, rollerg.cpp, sbasketb.cpp, simpsons.cpp, spy.cpp, thunderx.cpp, tmnt.cpp, tmnt2.cpp, tp84.cpp, trackfld_a.cpp, twin16.cpp and vendetta.cpp)
- La Cucaracha: Added GFX bank. Added base inputs and DIPs. Replaced video emulation with artwork based LED matrix. Added scrollx and scrolly. Fixed SFX playback at game start (missing OKI mirror). Game engine timer IRQ is more around 100 Hz, for lip sync at game start. LED colors closer approximation (layout\cucaracha.lay).
- Maze of Flott: Dumped PALs for Maze of Flott (Japan)
- Medal Mahjong Moukari Bancho: Identified some inputs

- Red Corsair: Fixed 6845 validation, attempt at decoding color proms and fixed CPU clocks.
- Robotron: 2084: Added prototype/location test version (Release 3), seen in the Robotron promo videotape that was recovered from a Vid Kidz development system. In 2026, early prototype builds of Robotron were found in a 2004 backup made by Duncan Brown. The backup was from the Vid Kidz GIMIX 6809 development system used to create Robotron and Blaster. It was discovered that there were six "release" versions of the game and that Releases 4, 5, and 6 correspond with Yellow label, Blue label and the '87 patch by Christian Gingras respectively. Releases 1, 2, and 3 are early builds of Robotron used during field tests. Release 3 is notable as it replaces the skull and crossbones graphic with an 'X' crossing out a generic human. This censored image can be seen in a promo videotape (also preserved by Duncan): https://youtu.be/j0tqQryAmN0?t=209. At the 2016 CAX show, Larry DeMar talked about Release 3 and revealed that Williams wanted to replace the art asset because they thought the violent imagery would negatively affect sales. Right before Robotron entered production, Eugene Jarvis convinced Williams president Mike Stroll to revert back to the original skull graphic.
- Ruleta Magica: Make it execute some code. Hook up UART. Basic video hookup. Map I2C EEPROM and Timekeeper.
- Seibu: Convert single irq to set_irq_acknowledge_callback (dynduke.cpp, goodejan.cpp, r2dx_v33.cpp, raiden.cpp, raiden2.cpp, raiden2.h, raiden2_v.cpp, raiden_ms.cpp, seibuspi.cpp, seibuspi.h and sengokmj.cpp).
- Strike Bowling: Correct coin inputs
- The NewZealand Story: tnzs/tnzsj audiocpu runs in IM1, no need for set_input_line_and_vector

- MAME
  . VIDEO RENDERING SYSTEM
    . Fixed drawing at the wrong resolution in the first window after resizing a window other than the first one. Also improved behaviour if the first window is resized while recording to AVI and got rid of some unnecessary file statics (render\drawbgfx.cpp).
    . Removed reel component. It's produced a warning for over four years, it's no longer used in internal artwork, and it never even really worked. Use std::countr_zero in place of loops (emu\rendlay.cpp). 
    . Added a helper for 6-bit BGR palettes (emu\emupal.cpp)
    . Split clear dirty function. Added function for clear dirty of all elements. Added gfx viewer specific getters (emu\drawgfx.h).
  . MEMORY SYSTEM: Gets rid of a layer of templating in emu\emumem_hedp.cpp and makes a few other things easier to read.
  . DEVICES
    . Added first-class concepts for a couple of things (emu\device.h)
    . Made object finders and similar things explicitly non-copyable. Copying them never behaved intuitively (emu\devfind.h).
    . There are a lot of clock information in device instanciation that gets a 0 because the information is not available or it just doesn't make sense. Allow them to be removed and push that to the constructors.
    . There are a number of cases where a weird interaction between DEFINE_DEVICE_TYPE_PRIVATE and pure methods make it impossible, see DL1416T for instance.
    . Removed default zero clock for devices that actually need the clock frequency. If you're disabling a device by setting the clock to zero, or setting it to zero with the intention of changing it later, you should be explicit about that.
    . Disable lost value logging by default, don't call it a warning (machine\gen_latch.cpp)
    . Fixed unloading media when the core doesn't open the file. Fixes, among other things, "[empty slot]" not working for MIDI ports (emu\diimage.cpp).
    . Mark set_input_line_vector and set_input_line_and_vector as deprecated (emu\diexec.h)
    . Use std::has_single_bit in various assertions and sanity checks (devices\bus\*, devices\cpu\*, devices\machine\*, devices\sound\* and devices\video\*)
  . INPUT/OUTPUT
    . Allow initialising output finders with arrays of matching dimensions. Also got rid of all but one of thee uses of get_value/set_value in emulation code and marked them deprecated. Fixed dangling reference (emu\output.h).
    . Updated API: Added a lightweight output proxy class for interacting with outputs from outside a device context. If an output doesn't exist, it stores a local value. Note that this means layouts cannot create outputs, e.g. to communicate between views. Outputs are only created by output finders when resolving objects. Made output finders participate in object resolution in the device lifecycle. They no longer need to be manually resolved. Conversely, you can't avoid creating outputs by not explicitly resolving them. Added some validation rules for output names. Got rid of the deprecated get_value/set_value. The Lua versions will stick around a bit longer to give people time to migrate. Some other internal API changes in preparation for per-device outputs. Shuffled the code for the output proxy move assignment operator to handle self-assignment properly (emu\output.cpp). Hopefully fix building with GNU libstdc++. Apparently GNU libstdc++ wants the opposite parameter order (emu\output.h).
    . Made outputs name scope local to devices. This allows multiple devices in the system to have outputs with the same names, paving the way for stuff like floppy drives exposing head position and motor state as outputs without needing to worry about coming up with unique names. For now, SVG items still use unqualified names, and layouts instantiated by the root device can use unqualified names (interface\output.h).
    . Reduced coupling and improved encapsulation. Removed input.h from emu.h - emulation code shouldn't be using it for anything besides debugging features, and even then it's not great as it's opaque and it's quite disconcerting, especially when the debugging keys conflict with default input assignments. Removed debug keys for a few systems/devices where it's a leftover for something that's fairly well understood (emu\input.cpp, emu\inputdev.cpp and emu\uiinput.cpp).
    . Updated output finder documentation (techspecs\object_finders.rst)
    . Network: Re-wrote to fix the worst of the implementation bugs. * Note that this doesn't change the protocol, it's still fundamentally unsuitable for things with large numbers of frequently updated outputs. It should work OK for a system with cabinet lamps now, but e.g. something with a bitmapped display won't work so well. * Allow clients to remain connected across multiple sessions if the user hard resets, launches another system from the system selection menu, etc. * Allow connections over IPv6. * Don't unsafely access the running_machine from worker threads. * Ensure buffers remain valid until asynchronous writes complete. * Only keep a single write per socket outstanding, batch up messages that arrive in quick succession into single writes. * Fixed obviously broken parsing of incoming commands, use of unsafe strtok, and assumption that one read completion will correspond to one command (commands must be terminated with CR or LF). * Shut down in an orderly fashion and wait for I/O to complete. * Made object lifecycles clearer, avoid accessing mutable state from multiple threads as much as possible, protect remaining shared mutable state with mutexes. * Added some error logging.
    . Use std::countr_zero in place of loops (emu\ioport.cpp)
    . Incrased maximum joystick buttons to 128. Cleanup. More compact button state, be explicit about where limits come from, removed some leftover crud (input\input_sdl.cpp and input\input_sdl3.cpp).
    . Moved stuff that isn't common out of the common header (input\input_common.h)
    . Allow using sdljoy input module with OSD=windows and USE_SDL=1 or USE_SDL3=1. Also fixed handling of joytick trackballs for OSD=sdl and OSD=sdl3 and fixed some issues building with OSD=windows USE_SDL3=1 (input\input_sdl).
  . UI
    . Added tilemap palette offset display. View full gfx regardless internal clip. Added clip status viewer (clip start : clip size). Display clipped gfx, and added offset in mouse overlay. Display tilemap palette offset in mouse overlay (ui\viewgfx.cpp).
    . Language translate support was missing from a heading string (frontend\mame\ui\utils.cpp)
    . Added -rtc command-line option for fixed baseline time overrides (emu\machine.cpp and emu\emuopts.cpp). Note: Specifies a fixed baseline time to initialize the real-time clock (RTC) chips emulated by MAME. By default, MAME initializes RTC chips using your host computer's current system time.
  . ROMLOAD: Fixed passing open mode as CRC to emu_file::open, be more explicit about where reference wrappers are created (according to valgrind). Hopefully avoid potential crash loading delta CHDs. Should address GitHub #15535. Unfortunatly this bloats the code a bit with template instantiations, but I can't think of a cleaner way right now (emu\romload.cpp).
  . LUA engine: Added Lua bindings for new public output API and added deprecation warnings to the wrappers that emulate the old API. Also updated the two affected internal layouts to use the new API. Removed some leftover crud (mame\luaengine.cpp).
  . 3RDPARTY
    . Updated zlib to upstream version 3.1.2. There are supposed to be empty directories at zlib/test/find_package_no_components_test and zlib/test/find_package_wrong_components_test but git doesn't have a way to represent that. Hard-code macros set by configuration script (3rdparty\zlib).
    . Fixed several errors in the transcendental helpers, including wrong parameter order (3rdparty\softfloat3\bochs_ext)
  . CHDMAN: Added a few Quantum Fireball templates as example for newer IDE drives (tools\chdman.cpp)
  . PLUGINS
    . New plugin for recording player behaviour (plugins\keypress\*)
    . Replaced use of deprecated function that has since been removed. Fixes LUA plugin portname if enabled bombs MAME at start (plugins\portname) (ID 09492).
    . Don't reload settings on a soft reset. Work around "start" callbacks actually being called on reset (plugins\autofire\init.lua).
  . Split midway project into bally and williams according to brand owner. Videa/Sente stuff from the brief period before it was acquired by Bally is still in the bally project.
  . Fixed regression with opening sockets (emu\image.cpp)
  . Merged NeoGeo project with SNK project
  . Fixed test for empty output test. Fixes "output" cheat code draws text on the screen. But this function doesn't work in 0.288. This happens in built-in cheat with 0.288, no problem 0.287 or plug-in cheat (mame\cheat.cpp) (ID 09467).
  . Initial checkin of Taito product numbers (taito\README.md). Added refs to non-taito folder mentions. Fixed formatting.
  . Added support for Atmel ATV750 (tools\jedutil.cpp)
  . Changed manufacturer name "Hudson" to "Hudson Soft". Various Taito, Hot-B and Wood Place games/drivers: Removed trade entity from manufacturer names (ID 06584) (ID 09480).
  . Consolidate drivers into single file (ampoker2.cpp, calomega.cpp, ladyfrog.cpp, namconb1.cpp, ninjakd2.cpp, nycaptor.cpp and punchout.cpp)
  . Bulk converted direct redump links to the new project site (hash\*.xml) (https://redump.info)
  . Bulk replace raw demo sound strings into the DEF_STR equivalent
- SDLMAME
  . Disable command line string escaping - fixes incorrect paarsing SDL_INI_PATH directive and build faild (GitHub #13150) (genie\src\actions\make\_make.lua, genie\src\host\scripts.c, osd\sdl3_cfg.lua and osd\sdl_cfg.lua)
  . Generally better handling of resizing windows and generating text input events for special keys (osd\sdl and osd\sdl3)
  . Statically link SDL for OSD=windows and USE_SDL=1 or USE_SDL3=1. Also set USE_SDL3=1 for Windows CI builds as the polling mode SDL joystick module won't be built in other configurations and it has legitimate use cases.
  . Enable SDL3 macOS click-to-focus behavior (sdl3\osdsdl.cpp)
- Compiling
  . Marked several device_t overrides as final. There's too much opportunity for confusion if these are overridden further down the tree (emu\driver.h; dooyong.cpp, trackfld.cpp...).
  . Retired operations that are in C++20  (osd\eminline.h)
  . Updated the rarely-used ci.flt
  . Converted several things from std::enable_if to requires clauses. Replaced most uses of enable_if with requires clauses. This uses requires clauses to replace enable_if in almost all cases where it was just used to exclude functions from overload resolution. This makes the code more readable. enable_if is still used for partial specialisation. Replaced remaining uses of std::enable_if and void_t with C++20 constraints and concepts. This makes some lines considerably shorter, to the point that some of them may even fit on your screen (emu, util). Brought back an enable_if as GCC doesn't seem to be able to deal with the alternative (util\dynamicclass.h).
  . Un-templated a number of functions. Several of these could have been un-templated when we adopted C++17 (due to if constexpr) but it wasn't done at the time. Also completely dropped C++17 support since requires clauses are a C++20 feature. Fixed formatting bool values with numeric conversions (util\strformat.h).
  . Use C++20 mathematical constants rather than M_PI and similar macros
  . Core header streamlining: Retired the util::endianness enum class in favor of the std::endian type introduced in C++20. Stripped save privileges from endianness_t (now an alias for std::endian), since its specific values may be nonstandard. This type is mostly used for configuration parameters anyway. Removed the endianness and floating point utilities from emucore.h. C++20 versions of the latter now reside in their own utility header (corefloat.h).
  . Added #include  for future-proofing (src\emu\*). Removed some empty device/machine_start (misc).
  . Put requires clauses on template parameter lists (util\delegate.h)
  . Removed default argument values from protected constructors. It's error-prone and leads to bugs. It also wasn't thought through very well. For example if a device actually tried to construct the base class in pc\pc_t1t.cpp with the default values that were added, it wouldn't do anything useful, it would just crash.
  . Improved compiling environment documentation. Link back to tutorial for Windows set up on main web site, better MSYS2 debugger recommendations, updated macOS/Xcode requirement for out-of-the-box building (docs\source\initialsetup\compilingmame.rst).
  . Header management: Removed inclusion of coretmpl.h from opresolv.h. Added #include  to source files that were using its functions, mostly for the sake of future-proofing (src\lib and src\tools).
  . Made asmjs buildable with latest emscripten 6.0.2
  . Started applying changes necessary to migrate to 64-bit offs_t. Mostly cribbed from GitHub #15295 with some additional cleanup and conflict resolution.
- Debugger
  . Added another example of how to use the 'ep' command (debugger\exceptionpoint.rst)
  . A couple of quality-of-life improvements: Memory and disassembler views inherit source/expression when opened from the same kind of view. Device windows show more information about address spaces and allow double-clicking to open a memory view. Properly treat names as UTF-8 in a couple of places (debugger\qt\*).
  . Play nicely with multiple monitors with different scaling. This fixes all the major/obvious stuff. There are some things that are hard-coded in the Windows debugger (e.g. EDGE_WIDTH and adding constant 4 pixels to the font height for the edit box/combo box height). Right now, the Windows debugger takes the suggested pixel size when moving a window to a monitor with different scaling. It may be better to adjust the size to keep the same character dimensions for the debugger views (osd\windows, debugger\win).
  . Added rp2a03g as m6502 alias to enable NES/Famicom debug (debugger\debuggdbstub.cpp)
  . Fixed a race condition and a QoL issue. The Cocoa debugger could push stale scroll position information back to the core. This manifested most often as the disassembly view refusing to update after stepping into a large PC move (JSR/JMP/TRAP or an IRQ gets taken), or the debugger console not scrolling automatically. QoL: disassembly views that track curpc (like the one in the main debugger window) should not restore to the saved PC from the .CFG file. Fixes the disassembly view not showing where the real PC is on debugger startup (osx\debugview.mm).

- CPU
  . AM9517A: Implemented V5x DMAU soft reset. Fixes (MESS) mpc2000xl reading SCSI CD-ROMs (machine\am9517a.cpp).
  . Dynamic Re-Compiling: Removed i686 recompiler back-end. Without a practical way to make Windows i686 builds, it's just going to rot. Also, x86-64 is now older than Pac-Man was when MAME was initially created. It's dead on the desktop (cpu\drcbex86.cpp).
  . Intel 8051: Changed address space names to resemble those used by Intel's tools. Fixed regression with sfr_map in derived classes (mcs51\i8051.cpp and mcs51\mcs51ops.cpp).
  . Intel 8086: Emulated undocumented DIV/IDIV behavior for the 80(1)8x as relied on by (MESS) MPC60 (i86\i86.cpp). Note: It's been observed on real 8086/8088 that DIV and IDIV set the zero flag in the expected manner according to the quotient.
  . Intel I386: Added CPUID brand ID for Pentium 3 and 4 (i386\i386.cpp and i386\i486ops.hxx). Avoid arithmetic between different enum types (i386\i386dasm.h).
  . Mitsubishi M37450: Port arrays were the wrong size (m6502\m3745x.cpp)
  . Motorola MC68000 (Musashi): Only allow one fault per instruction at a time (m68000\m68kcpu.cpp)
  . NEC uPD78C10: Fixed SET_Z on OFFI/ONI instructions (upd7810\upd7810_opcodes.cpp)
  . PowerPC drc: Fixed several errors in the 601 legacy POWER instructions. DOZI: The immediate value needed to be sign-extended, an unsigned comparison was used where signed is correct, and the operation is a subtract, not an add. DOZ: Same errors as DOZI minus the sign extension since there's no immediate involved. ABS/NABS: Fixed the condition register update. MASKIR: Flag update was trashing the result register and CR0 wasn't updated. Also fixed a typo in a comment for DIVWx (code was correct) (powerpc\ppcdrc.cpp).
  . Zilog Z86xx: Fixed disassembly of opcode D7 (LD x(r2), r1 - indexed register write). The register nibble roles were swapped and the operand order showed it as a read instead of a write. Both C7 and D7 encode byte 1 the same way (high nibble = r1, low nibble = r2). The only difference is operand order: C7 reads from indexed, D7 writes to indexed. Before: D7 DC 01 disassembles as "LD R12, 01h(R13)". After:  D7 DC 01 disassembles as "LD 01h(R12), R13" (z8\z8dasm.cpp).
- SOUND
  . MPEG audio: Added m_ prefixes to class variables (sound\mpeg_audio.cpp)
  . Namco C140: Assume keyon reg 0x40 is some kind of retrigger (sound\c140.cpp)
  . Namco C352: Make C352_LOG_PCM compile/work again and remove the #if (sound\c352.cpp)
  . RP2A0X APU: Make debug logging less noisy for various NES/VT devices (sound\nes_apu.cpp)
  . Sound Interface
    . Provide an explicit constructor (osd\interface\audio.h). Removed unused function declarations (emu\sound.h). Removed CoreAudio options that no longer do anything (lib\osdobj_common.cpp).
    . Crossfade abuffer on overrun. Update abuffer last sample on clear. Fixed std::memmove bytes param (sound\sound_module.cpp). Removed aueffectutil - it's no longer useful (tools\aueffectutil-Info.plist and tools\aueffectutil.mm).
    . Added noexcept specifier for XAudio2 engine callbacks (sound\xaudio2_sound.cpp). Fixed a convergence problem when a rate-adaptive stream is not connected (emu\sound.cpp). Fixes (MESS) Yamaha PSR-7x/PSS-6/11/12 freeze MAME at start (ID 09429).
    . Removed 'internal' param from get() (sound\sound_module.cpp)
    . Improved calculation of sound_requested_outputs_mask. Ensures m_sound_requested_outputs_mask is updated even if a device's add_route(output_index, ...) calls don't happen in the order of output_index (emu\disound.cpp).
    . Removed PW_STREAM_FLAG_RT_PROCESS flag due to race condition (abuffer get & push) (sound\pipewire_sound.cpp)
  . Yamaha YMZ770/YMZ774: Don't apply next prepared phrase volume/panning before current block finished. Fixes a burst of white static noise occurs in Pink Sweets, when certain voice clips play (ID 09408). Struct savestate issue (sound\ymz770.cpp).
- DEVICE
  . 2C0xxx PPU/PPC: Make debug logging less noisy for various NES/VT devices (video\ppu2c0x.cpp)
  . AT28C16 2Kx8 EEPROM: Small cleanup to indentation (machine\at28c16.cpp)
  . AT28xx/X28xx EEPROMs: Try to clean up the AT28xx/X28xx EEPROM mess. Duplicated sources in build scripts are bad. Non-existent sources are bad (they make trouble if you use a project generator that actually does something with headers, e.g. Visual Studio, CMake, etc.). Duplicated non-existent sources are really, really bad. Including a .ipp file from the header defeats the purpose. Also, you don't want to be rebuilding everything that uses the device for any implementation change. Virtual member function bodies should never go in the header unless there are performance-critical non-virtual calls to them that can be inlined (i.e. device_start, device_reset, nvram_default are not good cases for this). Inlined or defaulted virtual destructors are a bad idea as it makes it a lot harder to guess where vtables (and hence any other inline virtual member functions) will be instantiated. Unless there's a good reason or the class is a pure virtual interface, it's better to use out-of-line destructors.
  . Bus: Addressed unintuitive behavious in a dozen slot devices. With these slots, you'd get no options if you specified a clock frequency, or the default options if you didn't, or in a few cases, you'd get the options if you specified a default (even nullptr) or no options otherwise. It's completely unintuitive. This pattern shouldn't be allowed to creep back in.
  . DECO 104/146 Protection: Cleaned up code. Made fixed configuration constructor parameters. Suppress side effects for debugger reads properly. Made member variables private, reduced unnecessary includes. Use m_ prefix for member variables, use explicitly sized integers for values that are saved. Use logmacro.h for configurable logging. Use BIT helper to extract individual bits. Fixed descramble input.
  . Discrete Netlist: Avoid comparing enum to floatint point (sound\discrete.h). Check for mismatched number of parameters passed to device macros at compile time (lib\netlist\). Use C++20 __VA_OPT__ to simplify device registration code (netlist\nl_setup.cpp). Generate check for correct number of arguments (netlist\build\create_devinc.py).
  . Floppy
    . Allow specifying explicit start and end sectors when getting PC MFM track data. Ensoniq VFX and EPS family floppies use 10 sectors per track, starting at sector 0 rather than the more common sector 1. The code in 'esq16_dsk.cpp' handles this when loading floppy images, but not when saving them. This attempts to fix this in a way that is not only specific to Ensoniq's floppy images, but to possibly other future ones as well. In 'flopimg.cpp', allow specifying explicit start and end sectors when getting PC MFM track data. In 'esq16_dsk.cpp', use this to explicitly specifying sectors 0 to 9 when getting the track data to save (formats\flopimg.cpp and formats\esq16_dsk.cpp). Override number of tracks for .1dd format. Fixed booting in most if not all hash/smc777.xml FDC failures (formats\d88_dsk.cpp).
    . Allows definition of custom sound lists and fixes Amiga pitch glitches in floppy sound (imagedev\floppy.cpp/h). Allow matching extensions on string object names, rather than requiring a NUL-terminated string (formats\flopimg.cpp).
    . Fixed oob caused by m_step_samplepos dirty trick (imagedev\floppy.cpp)
  . Fujitsu MB87077 Volume Controller: Hook up MB87077 to the driving games (namcos21.cpp and namcos21_de.cpp). Changed gain to float (sound\mb87077.cpp).
  . Fujitsu MB89352 SCSI controller: Several bugfixes and a massive speedup. DREQ was not always dropping at the end of a SCSI transaction. This was causing data to get blasted to DMA before the chip was set up in some cases. The transfer counter could underflow when SCMD_TERM_MODE was in use. SCMD_RST_OUT wasn't actually resetting anything. Several delays were checked against the datasheet and found to be off by an order of magnitude. This was making SCSI-1 perform like floppy disks. (MESS) mpc2000xl and mpc3000 now have fully working SCSI. Both machines can format a disk, save and load data, and read CD-ROMs error-free. Previously they were struggling to even select a SCSI target, let alone send commands. Additional testing: Partitioned and formatted a hard disk on x68000 and I was able to load and run utilities from HDD on fz20m. This is your periodic reminder to make it easier for others to help you by providing software list images for computers/synths/samplers you write drivers for. And write setup instructions on wiki.mamedev.org (machine\mb87030.cpp).
  . H8 Serial Communications Interface: Added TODO note. Correct m_ssr_read logic (h8\h8_sci.cpp).
  . Hudson HuC6260 VCE + Data East Battle Rangers VCE: Made the battlera-specific VCE a separated device class (Data East Battle Rangers VCE). Also simplified binary manipulation (video\huc6260.cpp).
  . IGS023 Video System: Use BIT helper to extract single bits and util::sext to sign extend values. Use logmacro.h for logging feature. Use address maps for RAM/video register area. Implemented additional features: Sprite DMA, disable specific layer and ccanline counter (verified from hardware). Expanded palette area for fix possible out of bound text palette issue. Reference: https://github.com/laoo/PGMTech (igs\igs023_video.cpp).
  . Imgtool: Use UTF-8 console I/O on Windows, don't use wide char streams (imgtool\imgtool.cpp).
  . Intel 8251 USART: Sync mode fixes: Fixed parity handling for SYNC mode. Send sync characters when TX empty. Small cleanup (machine\i8251.cpp).
  . Kaneko RLE Compressed Sprite Hardware: Renamed Super Kaneko Nova sprite device and cleaned up code. Also fixed save state and debugger issues (kaneko\kaneko_rlespr.cpp).
  . Kaneko VU002 Sprites: Added double buffering. Use fixed size framebuffers to fix save state support. Implemented double buffered framebuffer. Fixed framebuffer clear behaviour - match as kan_pand.cpp (also double buffered) and real hardware (kaneko\kaneko_spr.cpp).
  . Namco 186/187 or C355/187 (sprites): Removed hardcoded namcos21 scroll adjust. Added notes. Removed assumption that it has 2 active spritelists (shared\namco_c355spr.cpp). Assume same C355 scroll for ds5000 and gal3 offset as namcos21.
  . Namco C123 (4x + 2x Tilemaps), Namco C169 (ROZ) and Namco 186/187 or C355/187 (sprites): Use device_delegate for callbacks. Added default behaviour when callbacks are unset (just copy directly from RAM).
  . Namco C148 Interrupt Controller: Fixed possible crash. Removed assumption that it clears all irqs when writing to any irqlevel reg. posirq line doesn't belong in this device. Assume 1d4xxx is busack. Make ext read a callback (namco\namco_c148.cpp).
  . Namco C45 Road: Use .m for address map instead trampolines. Removed device_memory_interface related stuff (not needed due to above). Made some variables const, use util::sext for sign extension. Reduced literal tag usage (namco\namco_c45road.cpp).
  . Namco System 21 3D Rasterizer: Fixed x/y end limits. Bit 7 of code really doesn't seem depth cue related, fixes Air Combat 3D colors. Guard against possible array OOB. Shorthand variable types. Removed some obsolete stuff. Z param can be negative. Added backface culling. Added per-poly representative Z (namco\namcos21_3d.cpp)
  . Namco System 21 DSP Setup (1x TMS320C25 type): Moved draw_quads to 3D device. Shorthand variable types. Removed winrun_ prefix. Saftety mask for possible array OOB. Different method for sending data to renderer. Added poly size mismatch check. Improved DSP comram (namco\namcos21_dsp.cpp).
  . Namco System 21 DSP Setup (5x C67 type)
    . Removed Cyber Sled specific kickstart delay, fixes title screen appearance. Issue a DSP chip reset when the line is high, fixes Solvalou and Starblade 3D graphics after exiting service mode (namco\namcos21_dsp_c67.cpp).
    . Reorder display command processing, fixes Cyber Sled crash after defeating round 3 in Vs. Computer Combat and Solvalou crashes during the first level. Removed obsolete yield_hack and other hacks. Moved draw_quads to 3D device. Shorthand variable types. Added a missing side effects check (namco\namcos21_dsp_c67.cpp).
    . Correct some dsp edge triggered ports and removed C67 underclock hack. Saftety mask for possible array OOB. Added poly size mismatch check (namco\namcos21_dsp_c67.cpp).
  . Namco WSG: Use device_memory_interface for waveform memory, allow config per hardware (ex: RAM in 20pacgal.cpp). Split Pole Position WSG into separate device. Added notes for polepos panning. Correct polepos sound device type. Added address map for common 15XX/CUS30 interface. Removed unnecessary configuration, use templated base class instead (also packed flag). Fixed mixing. Use logmacro.h for logging, reduced preprocessor macros and use references rather than pointers. Split device state for per-hardware differences. Fixed allocated size for sound register area. Made some variables const. Correct 20pacgal sound device type (sound\namco.cpp).
  . NEC V50/V53: Correctly clock the V50/V53 DMAU based on the input clock (nec\v5x.cpp)
  . NEC uPD7801: Fixed port C direction bits
  . PC LPT: Added PS/2 bidirectional mode support (machine\pc_lpt.cpp)
  . PCI: Set HCHalted on cleared Run/Stop bit (machine\pci-usb.cpp)
  . SCSI CD-ROM: Added a CDROM_2X device that reasonably throttles the read speed to what you'd see with a 2X CD-ROM drive (nscsi\cd.cpp)
  . SCSI Hard Disk: Allow only lun=0 for test unit ready (nscsi\hd.cpp)
  . SiS 630 Host-to-PCI Bridge: Removed debug_break on smiact trigger (machine\sis630_host.cpp)
  . SiS 630 VGA i/f: Hookup fast page address (video\pc_vga_sis.cpp)

- MAME
  . VIDEO RENDERING SYSTEM
    . Removed Altivec/VMX bilinear filtering implementation. PowerPC on desktop is dead (video\rgbutil.cpp).
    . Added support for update_partial(vpos,hpos) (emu\screen.cpp)
  . MEMORY SYSTEM: Added remove_addrmap (emu\dimemory.h) (drivers hnayayoi.cpp, pacman.cpp, pengo.cpp, route16.cpp, snowbros.cpp, stfight.cpp, system16.cpp and wiz.cpp)
  . DEVICES
    . Allow source and manufacturer strings to be deduplicated. This increases coupling between the "traits" classes generated for driver/device definitions and the device type implementation class, but it noticeably reduces static data size for MAME as a whole (emu\device.h and emu\gamedrv.h).
    . Take std::string_view tag in constructor (emu\device.cpp)
    . Partially revert "Only allow command line image creation when file is not found and save startup image name for error reporting before trashing it" from MAME 0.282 due to MAME bug: MAME no longer attempts to "create" sockets when using socket syntax with the bitbanger device (emu\image.cpp) (ID 09464).
  . UI/OSD
    . Removed misguided qualifiers (osd\osdsync.cpp). UTF-8 strings will use a distinct character type (ui\devopt.cpp). Added pattern explainations for -listbios (mame\clifront.cpp). Honour -noreadconfig for command line verbs (mame\clifront.cpp).
    . Fixed potential crash in Video Options menu on Windows (ui\submenu.cpp)
    . Forward pointer events to input modules (windows\window.cpp)
    . Rationalised use of menu item flags: Renamed FLAG_INVERT to FLAG_DEEMPHASIZE to better reflect what it does. The Lua equivalent "invert" has not been changed because it will likely break external scripts (mame\ui\*).
      . De-emphasise inherited values, matching the behaviour of the audio effect menus (ui\inputmap.cpp).
      . De-emphasise the main item text for de-emphasised items without sub-text and for items that are both disabled and de-emphasised. This makes items with inherited values visually distinct from disabled items while not affecting [ab]use of disabled items for informational text (ui\menu.cpp).
    . Started untangling some stuff (ui\menu.cpp and ui\ui.cpp)
    . Added options to pause when showing menus and to open menus in active window. Dim all windows when paused (ui\ui.cpp). Broke assumption that UI elements will be drawn in the first window (ui\ui.cpp, ui\menu.cpp and ui\viewgfx.cpp). Allow menus to migrate between windows on activation (ui\menu.cpp). Added an option to automatically pause when a menu is displayed (ui\ui.cpp, ui\moptions.cpp and ui\submenu.cpp). Added an option to open menus in the most recently active window (also affcts the profiler, speed display and popup messages). Patched up some rather disturbing code (mame\ui\*).
    . De-emphasize default values. Matches the input assignment and audio effects menus (ui\confswitch.cpp and ui\sliders.cpp). Fixed variable name auto-complete gone wrong (ui\ui.cpp).
    . Improved media control experience and cleaned up a lot of bad code (ui\*). Completely reworked logic - backtracking through menus is more intuitive and more context is retained when encountering an error (it should be a bit easier to follow the code as well) (ui\imgcntrl.cpp and ui\floppycntrl.cpp). Don't show the initial content selection menu when opening an image to read from while writing to a separate file (ui\floppycntrl.cpp).
    . Moved the logic to enumerate floppy formats into the menu, use headings and separators, use callbacks to notify when an item is selected, don't pop menus when an item is selected and avoid actual work in destructors (ui\filecreate.cpp). Fixed infinite growth when repopulating the menu, don't pop the menu when a port is chosen, use a callback to notify that a port is chosen, use headings and separators and in informative placeholder if no ports are available (ui\midiinout.cpp).
    . Don't show the option to write to a floppy diff (it still isn't implemented, it can be re-added if it's ever implemented), don't pop the menus when selecting an item and avoid actual work in destructors (ui\filesel.cpp). Show more detail in the info box below the menu for software items and presets, substantially simplified the code for walking media devices (ui\filemngr.cpp). Got rid of the media information menu and added media information to the system information menu (ui\info.cpp).
    . Allow immediately adjusting the hovered item with pen/mouse, saving a click (ui\menu.cpp). Fall back to settings from INI files later in the search path (frontend\mame\mameopts.cpp).
    . Make earlier INI files take precedence over later INI files at the same priority level (util\options.cpp). Updated documentation on INI file handling.
    . Better handling of active pointers when resetting items. Fixes items showing hovered state when they shouldn't. Not a regression, but more visible now than previously due to other changes. Also improved some metadata (ui\menu.cpp).
  . INPUT
    . Support SDL3 (input\input_dinput.cpp)
    . Made Win32 lightgun module usable with pen/touch (input\input_win32.cpp)
    . Fixed incorrect strings displayed for 4C_5C, 3C_4C, 2C_3C and 3C_5C. The array absolutely must stay in order. Also added an assertion to catch these errors early. Use a much less gross method of handling default strings (apparently someone forgot about function overloading). Retired the crosshair mapper member macros - they don't serve much purpose (emu\ioport.cpp).
  . LUA engine: Removed some deprecated stuff. Patched up some rather disturbing code (mame\luaengine.cpp).
  . 3RDPARTY
    . Sync AsmJit with upstream version 1.21 (3rdparty\asmjit). Sync GENie with upstream 1196 (3rdparty\genie).
    . Retired softfloat2. Migrated to SoftFloat 3 (cpu\i386, machine\i8087.cpp).
  . Use UTF-8 console I/O when built with UCRT (windows\winmain.cpp)
  . Avoid use of volatile assignement result as value (emu\validity.cpp)
  . Save state: Cleaned up interface for reporting error messages (emu\save.cpp)
  . Avoid arithmetic between different enum types (mame\infoxml.cpp)
  . Default-construct XML parser options (mame\cheat.cpp)
  . Actually report a failure to open a plain file rather than looking for files inside non-existent archives, making every error turn into "file not found". Adjusted error handling. Fixes some cases of failing to open files in archives (util\zippath.cpp).
  . Consolidate drivers into single file (lsasquad.cpp)
- SDLMAME/SDL3
  . Pump CF run loop before enumerating game controllers on MacOS. On MacOS, SDL3's GCController backend discovers USB game controllers asynchronously through the Core Foundation run loop. Without giving the run loop time to process, USB controllers (e.g. Xbox Series X/S) are not detected during initial enumeration (input\input_sdl3.cpp).
  . Process events after raising window on MacOS to ensure input focus. On MacOS, the window may not have acquired input focus by the time SDL_RaiseWindow returns. Pumping events after raising ensures the FOCUS_GAINED event is dequeued and m_focus_window is set before the input modules start polling, preventing the intermittent loss of keyboard and mouse input on startup. Fixes GitHub #10612 (sdl/video.cpp and sdl3/video.cpp).
  . SDL3 compile again on MacOS with pre-3.4.0 and a minor cleanup (input\input_sdl3.cpp and sdl3\sdlmain.cpp). Fixed linking on Windows with static SDL3.
  . Actually set the "key hold down disable" hint for MacOS (sdl3\sdlmain.cpp)
  . Don't write to listening sockets, it can cause SIGPIPE (file\posixsocket.cpp).
- Compiling
  . Switched language standard to C++20 and bumped compiler requirement to GCC 11. Hackery to allow UTF-8 strings as well as plain strings: Allow char8_t for names in field configuration helper (emu\ioport.h). Allow char8_t for descriptions and manufacturers (emu\device.h and emu\gamedrv.h). Allow char8_t message input (util\language.h). Allow char8_t format and string arguments with char output (util\strformat.h). Deal with UTF-8 strings as a distinct type (ui\videoopt.cpp).
    . Fixed things C++20 doesn't allow
      . Deal with UTF-8 strings as a distint type (ui\info.cpp, imagedev\cassette.cpp)
      . Avoid arithmetic between different enum types (ui\inputmap.cpp, debugger\qt\dasmwindow.cpp, debugger\qt\mainwindow.cpp, sound\coreaudio_sound.cpp, cpu\drcbec.cpp, mit\tx0_v.cpp, konami\3dom2.cpp, machine\mc68328.cpp, cpu\mips\mips1.cpp, cpu\mips\r4000.cpp). Avoid arithmetic between enum and floating point (dec\pdp1.cpp, konami\firebeat.cpp, mit\tx0.cpp, sound\lc7535.cpp and sound\spkrdev.cpp)
      . Avoid comparing enum to floatint point (sound\discrete.h). Fixed deprecated uses of volatile variables (gaelco\gaelco3d_m.cpp). Don't use UTF-8 qualifier on pure ASCII strings, just assume char is ASCII-like (ui\toolbar.ipp). Provide an explicit constructor (osd\interface\audio.h). Fixed uninitialised class member warning (util\server_http_impl.hpp).
    . Eliminated many temporary std::string objects. Also updated compiling documentation. Mentioned the possibility to use the x86-64 clang/libc++/ucrt environment with MSYS2 on Windows. Removed link to tools at mamedev.org - it's trivially easy to get an up-to-date MSYS2 environment by following the instructions (initialsetup\compilingmame.rst).
    . Got rid of another wannabe std::span (mame\luaengine_debug.cpp). Fixed another C++20 thing that apparently only breaks with some compiler/OS/Qt version combinations (qt\deviceinformationwindow.cpp).
    . Added support for building with MSYS2 CLANG64 with less fuss (makefile). Updated ClangCL build settings to C++20 (scripts\genie.lua).
    . Cleaned up some more stuff to prepare for 64-bit offs_t
    . Move build system adjusttment and fixes: Bumped minimum clang version to 13 - clang 12 is just too buggy. Assume Qt 6 will be used, dropped Qt 5 support. Fixed finding Qt headers on Fedora and hopefully other distros. Always use static SDL2 on Windows.
    . Removed support for SysV operating systems. They're dead on the desktop (file\posixptty.cpp, sdl\sdlprefix.h and sdl3\sdlprefix.h).
    . Removed outdated LUA compatibility macros. They weren't doing anything sincewe updated to LUA 5.4 (the compatibility options changed, but we just left the old macros in place, which no longer had any effect) (scripts\genie.lua, scripts\src\3rdparty.lua, scripts\src\tools.lua, scripts\toolchain.lua).
    . Target Windows 10 API. Removed MODERN_WIN_API flag. Retire superseded Intel C++ Compiler target.
  . Added support for VS2026: Local fix for GENie resource include directory bug, sent upstream as bkaradzic/GENie#572. Local fix to disable broken command line escaping and to use MPARAM instead of hard-coded -m64.
  . Got rid of MAME_DELEGATE_DIFFERENT_MEMBER_ABI hack. This was supposed to allow calling i686 "thiscall" member functions viaa free function pointer. It had been disabled for years as it stopped working in GCC. Simply having the code present breaks compiling with Clang 22.1 even when it isn't enabled (util\delegate.h).
  . Switch GitHub Actions Windows x86-64 workflows from MSVCRT to UCRT (github\workflows\ci-windows.yml and makefile). Updated version and pin hash for the msys2 setup action in the Windows CI (github\workflows\ci-windows.yml).
  . Don't generate errors for format warnings with GCC/UCRT (scripts\src\3rdparty.lua).
  . Removed unused member variables (netdev\pcap.cpp)
  . Added ATTR_COLD pass to PCI sound cards
  . Fixed errors linking jedutil and romcmp on newer Linux (src\tools.lua)
  . Address some GCC16.1 warnings. Turn off the sfinae-incomplete warning for GCC 16 (scripts\genie.lua).
- Debugger
  . Added Edit menu with clipboard shortcuts. The MacOS Cocoa debugger only adds Debug and Run menus to the menu bar, so standard Cmd+X/C/V shortcuts are never routed through the responder chain to the command input NSTextField. Add an Edit menu with Cut, Copy, and Paste items to enable clipboard operations (debugger\debugosx.mm).
  . Fixed Qt debugger build on Windows with Clang. Qt provides inline definitions of dllimport functions, which causes a warning. There are too many of them to practically leave the warning enabled for this module (osd\modules.lua). It's no longer possible to get a working Qt 5 setup with MSYS2, and there's no 32-bit Qt 6 package. Updated docs to reflect this (docs\source\initialsetup\compilingmame.rst). Fixed build with Qt < 6.6 (qt\debuggerview.cpp). Fixed build with Qt 6 on AArch64 (debugger\debugqt.cpp).
  . Use C++20 bit functions (tools\unidasm.cpp)

- CPU
  . Analog Devices ADSP21062 'Sharc': Hooked up flag pin outputs for the interpreter. Hooked up flag outputs for the recompiler, push out flag latch state when switching from input to output. Added a compile-time option to disable ASTAT flag update elision in the SHARC recompiler and fixed some recompiler front-end bugs. Disassemble unimplemented instructions executed in recompiled code, include tag in more fatal errors, use throw syntax to make it cleared it's an early out (sharc\sharc.cpp). Don't use memset to clear loop entries (sharc\sharcfe.cpp).
    . Implemented fixed point clip and saturating arithmetic in interpreter. Correct logic for generating carry/overflow flags in add-with-carry and subtract-with-borrow operations. Correct floating point clip calculation for Fx < 0. Implemented the LT, LE, GE and GT conditions properly (sharc\compute.hxx, sharc\sharc.h, sharc\sharcops.hxx). Implemented short word sign extension. Fixed DAG2 (PM) register display in debugger. Track AF dependencies when analysing instructions. Log analysed instructions when logging UML code. Removed misplaced break in sharc\sharcfe.cpp. 
    . More recompiler improvements: Implemented fixed point CLIP and add/subtract with carry for recompiler. Cleaned up and de-duplicated code for setting ASTAT flags on fixed point ALU operationf for recompiler and fixed AC flag for subract operations. Optimised generated code for fixed point dual add subtrat, PASS and COMP for recompiler. Reduced unnecessary ASTAT flag copies for recompiler and added more glue that will be needed for supporting saturating arithmetic. Cleaned up fixed point COMP code for interpreter (sharc\sharc).
    . Fixed Rn = Rx + CI - 1 ALU operation. Neglected to git add the change after copy/pasting complementary operation above (sharc\sharcdrc.cpp). Fixed several interpreter issues: Fixed carry flag calculation for subtract with carry. Implemented Rn = Rx + CI and Rn = Rx + CI - 1. Rn = Rx + 1, Rn = Rx - 1 and Rn = -Rx should saturate the result (sharc\sharc). Implemented saturation for ALU dual add/subtract in interpreter (sharc\compute.hxx). Better ALU emulation for interpreter: Implemented fixed-point ALU overflow sticky flag (AOS). More accurate implementation of Fn = -Fx, Fn = ABS Fx and Fn = PASS Fx. Implemented Rn = ABS Rx and Fn = ABS(Fx - Fy). Sorted computer function declarations and definitions to match order of instruction listings in documentation (sharc\sharc).
    . More ALU refinements for the interpreter: Set AOS on fixed point dual add/subtract overflow. Handle corner cases better for floating point MIN, MAX and CLIP. Cleaned up code for floating point COMP. More detailed emulation of floating point addition, subtraction and COPYSIGN and some minor optimisation for interpreter. Share interpreter code for some single ALU ops and dual multiplier/ALU ops and be stricter about Rn vs Fn. Fixed saturation without resorting to comparisons (sharc\compute.hxx).
    . More detailed floating point mulitply and add/sub emulation for interpreter. Set MV, MU and MI flags and corresponding sticky flags for multiplication.  Flush denormals to zero and set AV flag (and corresponding sticky flag) for dual add/subtract. More detailed NaN handling for both (sharc\compute.hxx).
  . Dynamic Re-Compiling
    . Allow recompiling CPU cores to define their own opcode descriptions. The base opcode description now only has the parts that are used by the base recompiler front-end. CPU cores are free to define their own extensions as they see fit without being limited to pre-defined fields. The base recompiler front-end is now a template, eliminating the virtual member functions. It no longer has any dependencies on libemu, which paves the way to decoupling the recompiler front-ends and allowing the instruction analysis to be tested without the rest of the emulator (cpu\*). Added some helpers (cpu\drcfe.h).
    . drcbex64.cpp: Avoid unnecessarily changing SSE mode on SETFMOD and when leaving recompiled code (cpu\drcbex64.cpp)
    . drcbearm64: Reduced unnecessary rounding mode changes. Don't set the rounding mode on SETFMOD if it hasn't changed. Fixed back-end getting confused about the rounding mode on entry (cpu\drcbearm64.cpp).
    . drcuml: Let C functions take any pointer/reference parameter (cpu\uml.h)
  . Hitachi SH-1/2/3/4: Cleaned up instruction analysis logging a little. Cleaned up register dependency analysis logging and fixed an instruction analysis bug (cpu\sh*).
  . Hitachi SH-2 (SH7604): Fixed three register access bugs: vcrd_w: Read m_vcrd instead of m_vcrc for FOV interrupt vector. dmaor_w: Use (old & data & 6) so AE/NMIF flags can actually be cleared. vcrb_r: Mask reserved bits 15 and 7 with 0x7f7f, matching vcra/vcrc/vcrwdt (sh\sh7604.cpp).
  . Hyperstone E1-xxxx: Re-wrote E1 instruction analyser. Reduced redundant code, track condition flag dependencies independently, fixed a number of bugs (e132xs\e132xsfe.cpp). Don't recalculate immediate values when generating code (e132xs\e132xsdrc_ops.hxx). Log analysed instructions in UML log when using recompiler. Allow recompiler to skip unused condition flag calculations. Also fixed some instruction analysis bugs. Skip more unnecessary flag calculations, use pre-calculated PC for updating G0 in memory when possible, better analysis of pre-calculated PC values when delay slots are involved (cpu\e132xs).
  . IBM PowerPC: Fixed floating point comparison flags. Fixes various things that were always broken with the C and ARM backends or worked by chance with the x86-64 and i686 back-end. Also commented out some constexpr for now (cpu\powerpc\*). End instruction sequences on encountering SC (powerpc\ppcfe.cpp). Modernised recompiler front-end code and improved instruction analysis logging (cpu\powerpc).
  . Intel 8086: Correction to adc/sbb overflow flag calculation. Initialize m_ea_timing table. Don't accept NMI at reset time. No need for that m_reset_time local variable (i86\i86.cpp and i86\i86inline.h).
  . Intel 80186: The invalid opcode is a trap (m_ip = m_prev_ip). BOUND is signed. Fixed iRMX interrupt mode. Improved BOUND logging (i86\i186.cpp).
  . Intel I386: Fixed SMM. Use the correct bits for DPL. Adjust CS for ppro+. Include the 486 (i386\i386.cpp). Fixed softfloat with GCC 15 optimizer. qword ptr also needs the fix (i386; 3rdparty\softfloat\softfloat.c).
  . MOS Technology 6502
    . Don't accept NMI at reset time. No need for that m_reset_time local variable. Small refactor to do_sbc_d to make it easier to see the difference between NMOS/CMOS (m6502\m6502.cpp and m6502\w65c02.cpp).
    . Modify SBC decimal adjust algorithm for 65C02, which differs from NMOS 6502 in edge cases. Allows 6502test.ssd (from mungre/beeb6502test repository) to pass test BCD-FC on (MESS) bbcm (m6502\w65c02.cpp) (ID 06769).
    . De-virtualize SBC implementation in w65c02, w65c02s, etc. (m6502\w65c02.cpp). Route core fetch/data/write paths through interruptible accesses. Added interruptible access regression test. Narrow interruptible access follow-up (m6502\m6502.cpp).
  . NEC Vxx: Correction to addc/subb overflow flag calculation
  . NEC V60 and NEC V810: Correction to addc/subc overflow flag calculation (v60\v60.cpp)
  . Texas Instruments TMS32020/C25/C26: Small optimisation and cleanup: Templated relevant member functions on ignore ARP hack avoiding a data member check. Made IRQ cycles a local - it's never needed outside the scope where it's used. Skip hold logic if hold read callback is unset. Templated some member functions with simple variations (tms320c2x\tms320c2x.cpp).
  . Zilog Z80: Don't accept NMI at reset time. No need for that m_reset_time local variable (z80\z80.cpp)
- SOUND
  . ICS2115 WaveFront Synthesizer: Suppress side effects for debugger reads and cleaned up code. Use logmacro.h for configurable logging, reduced duplication and made some local variables const (sound\ics2115.cpp).
  . Sanyo VLM5030: Fixed pin rising edge detect if state high val is not 1. Added _r/_w to handlers (sound\vlm5030.cpp).
  . Sound Interface
    . Don't send sound to osd if mute reason is ui related. Change abuffer resync to more abrupt (ID 09203). After abuffer overflow, reduce buffers to 1 instead of clear. It was still getting a buffer underrun sometimes after overflow when reduced to 1. Forward audio latency setting to abuffer. Derive min_buffers from max_buffers and added over/underrun stats. Updated sound_module notes. Audio latency is a float (emu\sound.cpp and sound\sound_module.cpp).
    . Forward latency to abuffer (sound\coreaudio_sound.cpp). Fixed wrong assumption that samplerate is fixed at 48000 (sound abuffer). Rate-limit the output stream so it doesn't queue up to infinity when you unthrottle (sound\sdl3_sound.cpp) (ID 09401).
  . Yamaha YMZ770/YMZ774: Removed hardcoded clock. Updated notes. Added sample rate auto selection (sound\ymz770.cpp).
- DEVICE
  . Cassette: Use helper functions from multibyte.h (formats\wavfile.cpp). Added support for cassette images in AIFF format (formats\cassimg.h).
  . Floppy: Let the controller idle during soft reset. Note: (MESS) MikroMikko 2 expects to read 0 from MSR while the FDC is in reset (machine\upd765.cpp).
  . Imagetek I4100/4220/4300 VDP: Fixed tilemap scroll in flip screen set (video\imagetek_i4100.cpp)
  . Intel 8253 PIT: Improved timing accuracy. The counter is loaded and decremented on the falling edge of CLK. GATE and GATE transitions (for edge-sensitive modes) are sampled on the rising edge of CLK. Mode 3 treats GATE as edge-sensitive. In modes 2 and 3, GATE has an immediate effect on OUT. Deferred the execution of 'set_clock_signal'. Removed 8253 timing workarounds from (MESS) sixtrak. Ensure the recent fix for mode 3 does not yet apply to 'set_clk' configurations (machine\pit8253.cpp).
  . Kaneko PANDORA GFX: Cleanups and updates. Use shortened typename value for consistency. Use BIT macro for single bit flags. Fixed loggings, spacings and namings. Make some variables constant. Reduced literal tag usages. Fill empty sprite gfx region to transparent. Removed unnecessary checks. Fixed comments (Original chip has 14 bit tile code, used at djboy.cpp and hvyunit.cpp). Added notes for sprite bitmap RAM. Fixed sprite trail and notes. Chip has double buffering, so this commit fixes sprite trail match to PCB (ex: airbustr).
  . Konami 051733 math chip: Reduced code size a bit (konami\k051733.cpp)
  . MagicEyes VRender0 SoC: Added DMA address direction. Use struct for timer for reduce duplicates. Added struct name for DMA registers for reduce duplicates. Added notes for DMA control register. Use BIT helper for single bit values. Replaced printf to logerror. Use static function for DMA address increment calculation (machine\vrender0.cpp).
  . Microtouch Touchscreen: Added the host interface microcontroller to make it easier to look at the program (disabled for now, will be emulated in the future).
  . PC LPT: Added address_map variant for ISA PnP targets. LPT port 279 is read only, writes are routed to ISA PnP mode (machine\pc_lpt.cpp).
  . PCI: Standardize minimum grant & maximum latency readbacks (machine\pci.cpp)
  . SCSI: Allow for connecting devices external to the bus (machine\nscsi_bus.cpp). Turn nscsi_device into an interface for easier composition. m_ify the variable names (bus\nscsi\* and machine\nscsi_*). Split HLE to a different file (machine\nscsi_hle.cpp). Finish deslotting and correct a number of things (bus\*, machine\*...).
  . SCSI CD-ROM: Support the revised BlueSCSI host transfer protocol which allows up to 64K per chunk instead of 4K (nscsi\cd.cpp)
  . SiS 6326 AGP/PCI card: Hookup PCI variant "SiS 6326 PCI card" and VGA in VMI space. Initial BitBlt implementation. Fixed pattern regs mode and mouse caret in notepad. Shuffle roms a bit. Added support for DVD variant. Preliminary line drawing (pci\sis6326.cpp).
  . SiS 630 VGA i/f: Start hooking up MD config pins, base hookup of TV Out space. Fixed lambda capture. Preliminary HW cursor. Added line compare "disable" and fixed display at 1600x1200. Added remaining Sequencer registers and improved logging. Added CRTC counter latches. Fixed bug with dxdiag setting the wrong ramdac mode from 16bpp fullscreen to 8bpp desktop. Implemented video overlay playback. Improved VCLK PLL handling (video\pc_vga_sis.cpp).
  . Slot device: Cleaned up interface. Added a helper for the common operation of replacing all options, setting default, and setting whether the slot is fixed (reduced boilerplate in slot devices a bit). Fixed a bug where slot options copied the supplied name but also required the string to remain valid for their lifetime. Use std::string_view for strings that should never be null. Reduced some duplication (emu\dislot.cpp).
  . VGA: Streamline VGA based PCI/AGP cards legacy structures (bus\pci\*)
  . VIA Apollo MVP3: Map ACPI_PIPC on 8-bit units, use a device_memory_interface workaround to avoid emumem mapping bug (machine\vt82c586b_acpi.cpp). Added IDE and ACPI irq routing (machine\vt82c586b_isa.cpp).
  . Xebec S1410 5.25 Inch Winchester Disk Controller: Return seek error on out-of-bounds seek (nscsi\s1410.cpp)
- battlex.cpp: Set_flip_screen already marks tilemaps dirty. Removed unneeded variable.
- bfm_cobra3.cpp: Attempt to improve non-MPEG hardware parts. Added CD-ROMs to c3_ppays, c3_tellyns and c3_totp. Redumped c3_telly CD-ROM.
- cdi.cpp
  . Added Audio Mixing: CD-i audio mixing now largely working. To verify, try Zelda Wand of Gamelon and notice the audio now fades correctly. Added Audio Attenuation Storage. Breaks existing savestates. Reduced crashes from Audio. Previously, attenuation commands were not processed resulting in executing data bytes as code. This placeholder properly skips 5 bytes, increasing stability of the system. Reduced Audio Peaking. Changing to 0.25 removes some noticeable audio peaking. For example, the intro Philips logo (philips\cdi.cpp).
  . CD-i CDIC: Removes unnecessary memory allocation in CDDA decoder. The class already has m_samples prepared for this purpose. Simplify XA Audio. This removes an allocation of 56 bytes by instead using an orphaned array which was intended for this purpose. Added Attenuation Math (philips\cdicdic.cpp).
- chamrx1.cpp: Expand motherboard notes
- chihiro.cpp: Added another DSP56362 as the encode procesor DSP to the audio APU. And when the DSPs exit reset copy 24 bit words from Pentium processor RAM into DSP program RAM (shared\xbox_pci.cpp).
- cv1k.cpp
  . Added cv1k SH7709S cache handling behavior for slowdown emulation. Handles some basic caching for the sh7709s used for cv1k titles so that they run at more appropriate speeds.
  . Hitachi SH7709S: Fixed up a couple of timing handling bugs. Use the writeback flag instead of write flag as the access to external memory is what matters for those. Fixed up the writeback buffer timing, we don't need to precharge twice for writes. Also rolled up the command costs the SDRAM region handling so the writes only need to add trwl to the penalty. Check for burst mode availability when determining the base cycle cost, only burst ROM and sdram can use burst access to each other area requires 4 separate accesses. Added some comments explaining missing/unimplemented features. Added the non-burst timing table for WCR2. Updates and adds a couple of extra comments related to the penalties/timing. Fixed bug in DRC memory accessor using clobbered IO reg (#15074). Fixed a shift error in the wcr1 register values. Added bcr2 plumbing for determining cache line fetch reads based off BCR2. Area 0 is set via external pins so hardcoding the cv1k value, this is typically code space though so it only affects timing during copy of code to main memory. Convert the cpu cycles to bus cycles properly. Update bank conflict precharge penalty timing. Handle the precharge of the last active bank in the background and only pay the penalty on a bank conflict and only pay the remainder of the wait cycles that haven't elapsed since the last access. Update the read->write wait penalty time for dirty writeback eviction since wcr1 should contain that value. Fixed LRU cache replacement updates. Only update LRU values greater than the current LRU value on cache hit (sh\sh7709s.cpp).
- ddenlovr.cpp: Use slotted control panels. This is most useful for the games that can support several panel types, especially when the Hanaroku panel is supported. Added preliminary support for Hanafuda Hana Gokou joystick controls and improved some DIP switch settings a little. Allow a mahjong panel to be connected for all hanafuda games with slotted control panels. This is how the games were operated most of the time, and all mahjong controls are displayed in input tests. Also cleaned up some DIP switch settings.
- fdek_h8s.cpp and namcos6.cpp: Added info about other games in the same medal serie
- firetrk.cpp: Added DIP locations

- galgames.cpp: Dumped BIOS version 1.71. Note: v1.71 program ROMs were preproduction ROMs and there are known issue with memory management. Using v1.71 with StarPak carts will produce freezing and possible stability issues.
- galivan.cpp: Removed button 3 in dangar. Hold galivan's button 3 to move while hanging. ninjemak button 3 is on 0x40 according to testmode (although no button 3 on cpanel). Tweak galivan's screen raw params (it *is* measured, see PCB notes).
- gamtor.cpp: Added some system base ROMs. Created a new device with a hopper inside.
- gfamily.cpp, pulltrig.cpp and sis630.cpp
  . Moved ACPI implementation in own core. Added enough SMI glue logic (machine\sis950_acpi.cpp). Added pin mapper. Hookup relocable IDE IIRQA/IIRQB pins (machine\sis950_lpc.cpp). Added PCI slots to base SiS 630 driver.
  . Fixed subsystem write once in GUI and device ID for bridge (machine\sis630_gui.cpp)
- gng.cpp: Updated notes after msg from dink about palette glitch. Note: Writing to palette during active display causes bus conflicts, this happens at busy moments and the vblank routine overflows to the next frame. The glitchy 'lightning' effect is currently not emulated.
- iteagle.cpp: Use put_int_clamp on samples output (sound\es1373.cpp)
- jalmah.cpp: Added the actual references for some of the MCUs in filenames
- kaneko16.cpp: Added licensees to metadata and tidied code
- kontest.cpp and mogura.cpp: Small cleanup/improvements. Only loop over 8*8 blocks that need to be drawn (kontest.cpp).

  . Improved metadata: Added region-specific titles to descriptions, and explanatory comments. Added assumed regions to descriptions based on game UI language. Fixed toride2gg set title (non-adauchi gaiden set unlike previously described metadata). Added distributor metadata for lastfortk set. Use the standard mahjong matrix (metro\metro.cpp).
- model3.cpp: Dot product for lighting effects can't be negative by definition (sega\model3_v.cpp)

- pgm.cpp: Added notes for Debug feature (same purpose as pgm2 Debug DIP) and DIP switch positions.
- sammymdl.cpp and sigmab98.cpp
  . Separated Sammy medal games from Sigma B-98 driver. Made TAXAN KY-3211 and KY-10510 Sprite generator into separate devices (video\ky3211_ky10510.cpp).
  . Cleaned up code. Use multibyte helpers for 16-bit parameters, use BIT helper to extract bits. Reduced duplication, improved names. Use abbreviated integer type names consistently. Updated notes.
- segas32.cpp: De-slotize MB87030/MB89352 (machine\mb87030.cpp)
- sigmab98.cpp: Cleaned up code. Marked 'Minna Atsumare! Dodge Hero' as MACHINE_IMPERFECT_TIMING. Its title screen runs faster than should, which causes desyncing title call.
- snk6502.cpp: Added/Fixed screen raw params. Removed unneeded high freq timer.
- snowbros.cpp: Fixed comment order sort to MSB first and same byte. Split driver states per hardware configs. Simplified sound bankswitch method for snowbro3 and clones. Reduced duplicates. Fixed toto dip switch config for describe broken title screen. Added korean titles when exists. Fixed metadata due to title screen.
- statriv2.cpp: Got rid of tag lookups, made use of derived classes and other small cleanups. Updated notes.
- stellafr.cpp: Added/Redumped DSP rom
- taitojc.cpp: Changed screen raw params (matches vsync measurement 99.999%)
- tmnt2.cpp: Removed unneeded variable. Added VIDEO_ALWAYS_UPDATE flag to Golfing Greats.
- trackfld.cpp: Cleanup. Consolidate in single driver file (except for audio device). Use same raw parameters for screen as contemporary Konami games (konami\trackfld.cpp). Inputs don't magically change on reset. Also tidy some stuff up (konami\trackfld_a.cpp). Use scanline timer for NMI generation as in parent set for clone Yie Ar Kung-Fu (bootleg GX361 conversion).
- Battlezone: Removed space from title (ID 09414)
- Beast Busters: Correct dipswitches in clones Beast Busters (US, Version 2) and Beast Busters (US, Version 3) (ID 09407). Removed Player 3 in clone Beast Busters (Japan, Version 2, 2 Player).
- Blocken: Added PCB info and ROM locations
- Blood Bros. and Out Zone: Added PCB infos
- Caliber 50: Handle Caliber 50 sub CPU reset write
- Car Jamboree: Improved priorities, assume 0x8800-0x8807 is a 74259. Fixes the player car jumping on the ramp where one part disappears because of sprite priorities.
- Come On Baby: Improved device selection a bit (machine\it8671f.cpp/h).
- Dingo: Don't accept NMI at reset time. No need for that m_reset_time local variable (z80\z80.cpp). Fixes Dingo soft reset doesn't work (ID 09411).
- DJ Boy: Fixed initializer. Reduced duplicated comment block. Added notes for bankswitch entry.
- Fruit Land: Demoted game to GAME_NOT_WORKING. Even before the current boot regression it wasn't really working well (video with half height).
- Gals Panic: Restrict foreground bitmap draw routine to screen cliprect
- Gals Panic 3: Cleaned up code: Suppress side effects for debugger reads. Reduced unnecessary memory accesses in RLE decompression. Made some variables const, use abbreviated integer types consistently. Don't split initialisation between files (kaneko\kaneko_grap2.cpp). Cleanup driver: Replaced macros with lambdas and reduced literal tags. Updated notes. Use abbreviated integer types consistently.
- Games Family: Updated QA notes.
- Heavy Unit: Removed empty override
- Kangaroo: Fixed lockup regression in clone Kangaroo (bootleg)
- Kuzmich-Egorych: Improved video timing. Added 80STORE and NEWVIDEO beam-racing. Several fixes to match hardware: Added missing softswitch beam-racing support: C001 80STORE  (effectively toggling PAGE2) and C029 NEWVIDEO (.: 32 colors per scanline is possible). Followup #14053: make C068 STATEREG participate in beam-racing. Fixed C055 PAGE2 to work with 80VID. Encapsulate update_now() handling for C022 and C034 colors (apple\apple2video.cpp).
- Mahjong games: Added a simple slot system for standard mahjong and hanafuda matrix panels (up to 6*6) (shared\mahjong.cpp) (Drivers: ddenlovr.cpp, dynax.cpp, fromanc2.cpp, fromance.cpp, homedata.cpp, igs011.cpp, igsmahjong.cpp, mahjong.cpp, metro.cpp, ms32.cpp, royalmah.cpp, seibuspi.cpp, seta2.cpp and ssv.cpp)
- Mario Bros.: Walk sound trigger is from WR pin instead of D0. Put the masao bootleg in a subclass (ID 08997). Enable DYNAMIC_TS for clearer sound (nintendo/nl_mario.cpp). Added note about MCU internal rom: Dump M58715 internal ROM. The EA pin dumping method does not work, is the MCU read protected? It's probably a small initialization routine, followed by a jump to external ROM. MAME has a fake bootstrap for now.
- Monte Carlo: Small correction to car colors
- Neo Mania (Portugal): Initial Neo Mania Adapter JAMMA board (centronics\neomania_adapter.cpp). Added MACHINE_UNEMULATED_PROTECTION flag. Note: Once in non-Safe Mode Windows (after drivers installation etc.) the OS has a Startup item for the frontend (neofend.exe). If protection fails it will proceed to *wipe out* the entire HDD, it is advised to backup the .dif before fiddling with that.
- PC hardware: Sort out notes of several PC based Arcade drivers
- Pooyan: Added screen raw params
- Popper: Lower CPU quantum
- Revolution X: Added DIP locations
- Run and Gun: IRQ 5 enable bit comes from a different register. Fixes 'Fatal error: execute_command called with invalid command' when you try to change game difficulty in the dipswitches (F2) in Run and Gun (ver EAA 1993 10.8) (ID 08775). Added sound mute. Removed EEPROMOUT port.
- Sand Scorpion: Fixed CALC1 naming (CALC1 hasn't any MCU core)
- Space Guerrilla: Removed hardcoded color table. Added DSW locations. 8-bit palette data can't come from 5-bit colorram, so implement it differently (no visible change). Also added flipscreen.
- Star Wars Arcade: Pilot stick y was wrong way around
- Super Cross II: Assume Z80B is 5MHz and screen refresh rate is closer to 60Hz. Fixes occasionally writes wrong tiles to bg tilemap (ID 09395). Updated notes. Changed video emulation to tilemaps. Added flipscreen and fixed savestates. Small cleanup and update notes.

- Fixed rom names in exprraid.cpp, jalmah.cpp, namcos22.cpp and shangha3.cpp
- Renamed (gng) to (gngb), (gngc) to (gng), (gnga) to (gngc) and (radikaldrt) to (radikald)
- Dipswitch fixes in bbusters.cpp, bfm_cobra3.cpp, ddenlovr.cpp, nemesis.cpp, spaceg.cpp, sprcros2.cpp, statriv2.cpp, snowbros.cpp and midxunit.cpp
- MAME
  . VIDEO RENDERING SYSTEM
    . Fixed configure issue if main-mcfg doesn't use set_raw and sub-mcfg does (emu\screen.h)
    . Normalize blue palette (ambush.cpp, appoooh.cpp, bankp.cpp, btime.cpp, chaknpop.cpp, drmicro.cpp, gberet.cpp, jack.cpp, liberate.cpp, mrjong.cpp, shootout.cpp, snk6502.cpp, sprcros2.cpp and yiear.cpp).
    . Set all scroll rows/cols on single param scrollx/y (emu\tilemap.h)
  . DEVICES: Notify on changing preset images (emu\diimage.cpp)
  . UI: Fixed some cosmetic issues (ui\filemngr.cpp and ui\prscntrl.cpp). Include fastforward in unthrottle_mute (ui\moptions.cpp and ui\ui.cpp). Use osd_printf_info output for interactive verbs (mame\clifront.cpp).
  . 3rdparty
    . Updated some use of deprecation ASIO APIs (util\client_ws.hpp, util\server_ws_impl.hpp, capcom\cps2comm.cpp)
    . Fixed softfloat with GCC 15 optimizer. qword ptr also needs the fix (i386; 3rdparty\softfloat\softfloat.c)
  . INPUT: Added 3P and 4P hanafuda controls and moved some gambling controls to the "other" group (emu\inpttype.ipp). Got rid of IPT_GAMBLE_SERVICE (emu\inpttype.h).
  . Reduced temporary objects and duplicated code (emu\xtal.cpp)
  . Consolidate drivers into single file (lastduel.cpp, seta2.cpp, trackfld.cpp and tumbleb.cpp). Small cleanup (appoooh.cpp, chinsan.cpp, jantotsu.cpp, jongkyo.cpp, ron.cpp and sprcros2.cpp).
- SDLMAME/SDL3
  . Implemented SDL_MouseWheelEvent integer member fallback for version less than 3.2.12. Added fallback for SDL_MouseWheelEvent when build with SDL3 < 3.2.12 (input\input_sdl3.cpp and sdl3\osdsdl.cpp).
  . Set hint to disable the accents popup on MacOS when holding down keys (sdl3\sdlmain.cpp). Some fixes for -attach_window functionality under SDL3. Ensuring that when -attach_window that some inappropriate properties (e.g. - 'SDL_PROP_WINDOW_CREATE_TITLE_STRING') are not specified. Ensuring that under X11, we invoke 'XSelectInput()' with our own mask rather than what SDL3 does by default. Windows support. Attempting to fix MacOS specific warning (sdl3\sdlopts.h, sdl3\window.cpp).
  . Fixed black screen when launching with -video soft on MacOS (render\drawsdl3soft.cpp). Render OSD at native resolution on scaled high DPI displays (render\drawsdl3accel.cppand render\drawsdl3soft.cpp).
  . Autodetect Homebrew SDL3 on MacOS (scripts\src\osd\sdl3.lua).
- Compiling
  . Allow USE_SYSTEM_whatever=0 to use local copies of third party libraries (scripts\src\3rdparty.lua)
  . Improved building in more configurations (makefile, scripts\genie.lua, scripts\src\3rdparty.lua and scripts\src\lib.lua)
  . m_ify the variable names (cpu\m6502\*)
  . Some prep work for extending offs_t to 64 bits. This covers some of stuff highlighted in GitHub #14689 where the approach to apply is reasonably obvious and the changes are harmless when offs_t doesn't change size. Most of this is being more strict with offs_t vs uint32_t and switching to type-safe formatting functions.
  . Bulk change osd_printf_warning -> osd_printf_info for LOG_OUTPUT_FUNC.
- Debugger
  . Stop the windows debugger from crashing when using a widescreen monitor. Happened with text windows wider that 256 characters (win\debugviewinfo.cpp).
  . Use C++ file stream for dumping address maps (debug\debugcmd.cpp)
