- CPU
  . Analog Devices ADSP21062 'Sharc'
    . Include emu.h. Implemented 16-bit IOP write handling. Added missing DMA members to save states. Implemented bit-accurate RECIPS and RSQRTS in recompiler (fast approximation can be enabled by setting a macro) (sharc\sharc.cpp).
    . Fixed/optimised RECIPS flag calculation for interpreter. Fixed FIX for negative numbers when MODE1 TRUNC bit it set for interpreter and recompiler (should round towards negative infinity). Don't regenerate static helpers on cache flush (sharc\sharc.cpp).
    . Better align FIX between interpreter and recompiler, pack/unpack recompiler ASTAT for saved states. Cleaned up memory access a bit, use memory_access::specific and added ADSP21060 (larger internal SRAM) (sharc\sharc.cpp).
    . Always enable SHARC recompiler in the Konami drivers konami\gticlub.cpp, konami\hornet.cpp and konami\zr107.cpp before start.
    . Improved memory access code: Exploit data memory layout to bypass the memory system for both 32-bit and 16-bit SRAM accesses. Exploit the way the SHARC toolchain lays out executable code and data in SRAM to greatly reduce unnecessary cache flushes. Implemented Rn = NOT Rx (used by Sega Model 2B games). Align 32-bit program memory accesses with the most significant bit of the bus (corresponds to interpreter change in MAME 0.278 GitHub #13770). Get past DSP program crash in Midnight Run (sharc\sharcdrc.cpp)
    . Better handling of cache reset at end of block (sharc\sharc.cpp). Fixed more instructions: Fixed multiply/average and multiply/absolute for interpreter - the ALU operations produce a floating point result. Implemented move from multiplier register, multiply/average, average and FDEP with immediate field specification for recompiler. Use a more accurate approach for the absolute value calculation in multiply/average and average rather than hoping the C library does the right thing for the interpreter and recompiler (sharc\sharc.cpp, sharc\sharcdrc.cpp, sharc\compute.hxx).
    . Allow multiple loops to end on the same instruction. This is required by Last Bronx, which has code that de-duplicates the common part of multiple successive loops. It reduces the performance of do-nothing spin loops a bit but not too much - the DRC still has substantially better performance than the interpreter. Unfortunately, this exposes a pre-existing issue with how ASTAT conditions are handled in the SHARC front-end which causes the Midnight Run and Racing Jam DSP programs to crash. Fixing it will require major changes. Use -nodrc for now, I'll probably have to disable to recompiler before the next release until this can be fixed (sharc\sharc.cpp).
    . Tidied code a bit: Helper functions for getting commonly extracted opcode fields. More symbolic constants and fewer magic numbers. More constexpr helper functions, fewer macros and safer macros. More const local variables (cpu\sharc).
    . Improved reset conditions, prevent program from writing read-only STKY bits. Fixes 'Midnight Run' crash when F3 pressed (ID 07295). Improved status stack handling a little. Also actually implemented ASTAT/MODE1 save/restore for recompiler (cpu\sharc).
    . Overhauled PC stack implementation: Always access top-of-stack through the pseudo-register value. Better behaviour when PC stack is empty. Implemented effects of writing to PCSTKP. Mask PC stack values to 24 bits. Try to get PC stack into a consistent state after loading a saved state. Also fixed loops with initial counter value of zero (should iterate 2^32 times) (cpu\sharc).
    . Implemented a bit more channel 6 DMA. Fixes changing settings in Pilot Kids service mode menus.
    . Overhauled loop stack handling. Always access top-of-stack through pseudo-registers. Better behaviour when stack is empty or full. Implemented more read/write top-of-stack and explicit push/pop operations. Try to get loop stack into a consistent state after loading a saved state (cpu\sharc).
    . Better ASTAT handling: Flag pin bits are unaffected by push/pop status. Only flags set to input follow inputs on flag pins. Implemented ASTAT write for recompiler. Show ASTAT value in debugger when recompiler is enabled. Also don't allocated DRC cache when recompiler is disabled. Better sync on input changes across scheduling domains (cpu\sharc).
    . Pause DMA when stalled with recompiler to match interpreter. Disabled stalling DMA with recompiler for now. Current implementation gets confused, breaking Thrill Drive on Hornet (cpu\sharc).
  . Dynamic Re-Compiling
    . Fixes and refinements: Fixed crash when the CPU generates code during device_start and the debugger is enabled (devices\cpu/drc*).
    . drccache: Initialised all data members (cpu\drccache.cpp)
    . drcbec: Added support for invariant code and code blocks. Removed a bunch of crud that shouldn't be there. Restore floating point rounding mode if an exception is thrown, use C99 nearbyint/nearbyintf. Work around older clang that doesn't support the floating point environment access pragma (cpu\drcbec.cpp)
    . drcbeut: Added support for invariant code and simplified DRC label list class (only used by C back-end) (cpu\drcbeut.cpp)
    . drcbex86, drcbex64 and drcbearm64
      . Added support for invariant code blocks and made helper code invariant (cpu\drcbex86.cpp, cpu\drcbex64.cpp and cpu\drcbearm64.cpp).
      . Call (rather than jumping to) the entry point handle. The UML HANDLE instruction points to a minimal function prologue, which expects the conditions immediately following a call. However, the back-ends were jumping to it directly after setting up the top-level stack frame. On x86-64 and i686, this resulted in the stack being misaligned until a HASHJMP or EXIT instruction was executed. Anything that could result in a C function being called (CALLC, DEBUG, BREAK, READ, READM, WRITE, WRITEM, FREAD, FWRITE) could crash due to stack misalignment, and RET would crash due to the return address not being in the expected location. On AArch64, the stack would not be misaligned, and calls to C functions would work correctly, but RET would result in exiting from generated code without restoring callee-preserved registers. The C back-end just hits an assertion failure if the entry point code executes a RET (cpu\drcbex86.cpp, cpu\drcbex64.cpp and cpu\drcbearm64.cpp).
      . Restore floating point environment when calling out to C code (cpu\drcbec.cpp, cpu\drcbex86.cpp, cpu\drcbex64.cpp and cpu\drcbearm64.cpp).
    . drcbearm64: Identify more valid bit mask immediates (saves an instruction and a temporary register, e.g. when clearing a small contiguous field in an integer) (cpu\drcbearm64.cpp).
    . drcuml: Added support for invariant code blocks. Include device tags in UML/native generated code log file names (kind of important when a system has two of the same kind of CPU) (cpu\drcuml.cpp).
    . hyperstone E1-xx and PowerPC DRC: Made static helper code invariant (e132xs\e132xsdrc.cpp, powerpc\ppcdrc.cpp)
  . Ensoniq ES5510: Fixed opcodes in ES5510. ABS uses operand B. CMP runs even when skippable and only updates flags (no dst write). SIGREG bit 22 drives mul shift. CCR/CMR readback encoding. ABS should update zero flag. ASL2/ASL8 overflow/carry/flag logic (es5510\es5510.cpp).
  . MIPS-III: Added missing header that was being #included indirectly (mips\mips3com.cpp)
  . Motorola MC68LC040: Fixed the 68LC040 so it actually has 68040 opcodes (m68000\m68kcpu.h)
  . Texas Instruments TMS34010: Fixed 32-bit pixel writes (tms34010\tms34010.cpp)
  . Toshiba TMP95C06x: Added model-specific LDC control register names for DMA registers. Implemented EI/RETI interrupt acceptance shadow (cpu\tlcs900/*).

  . Coin1/2 were the wrong way around. Added NVRAM. Removed some unneeded variables and clock macros. Removed OLD_SOUND discrete sound emulation and MCU macros (nintendo\mario_a.cpp). Added shared base memorymap. Removed some mario_ function prefixes. Use retry_access trick to sync 2-way cpu comms. Changed clone Masao audio clocks. Correct some romlabels.
- Mega Double Poker: Marked Mega Double Poker and clone not working. Note: They've failed to boot for a while now. Also reduced duplication and literal tags a bit and got rid of a bankdev.
- Monkey Magic: Added note about xtal. Reorded dsw settings from low to high.
- Moon Raker: Added the starfield rom
- NBA Hangtime: Dumped security PICs
- P's Attack: Hookup EEPROM and CF slot rather than HDD
- Pango Fun: Create new UM8498F chipset. Guess shadow RAM location. m_kbrst is high at startup (machine\um8498f.cpp). Get rid of pcat_base_state. Added ISA slots and replace baked in Trident ROM + bare VGA with actual AVGA1 (pc\pangofun.cpp). Added 'Cirrus Logic GD5401 AVGA1' card support (isa\svga_cirrus.cpp).
- PC-Engine (battlera.cpp, ggconnie.cpp, paranoia.cpp, tourvis.cpp and uapce.cpp)
  . Make some variables constant. Reduced preprocessor macros. Use abbreviated type names and BIT helpers (Common PC-Engine hardware. See reference at: http://daifukkat.su/pcfx/).
  . Added input clock for video hardware (battlera.cpp and ggconnie.cpp)
  . Use XTAL for main clock. Reduced duplication. Fixed save state issues and initializers. Added notes for sound routing (ggconnie.cpp, paranoia.cpp, pcecommn.cpp/h. tourvis.cpp and uapce.cpp).
  . Improved logging (nec\pce_cd.cpp)
  . Hudson HuC6202 VPC: Reduced duplication and use more member arrays (video\huc6202.cpp)
  . Hudson HuC6260 VCE: Fixed initializer and save state issues. Made screen update function directly usable with screen device (video\huc6260.cpp).

- Pull The Trigger: Added base sis630 chipset
- Qianxi Jielong: Fixed palette. Added Oki ROM banking.
- R2D Tank: Added note about older version: R2D Tank is a cost-reduced 'sequel' to "Red Tank", Sigma probably contracted Orca to simplify the hardware. The first version (Red Tank) is on 2 PCBs with "FUJIDENSHI" on the EPROM labels. Sigma's "The Goku" is on the same earlier hardware as Red Tank.
- Reality Tennis: Replaced macros with constexpr
- Silent Scope 2: Removed badly dumped ROM that would fail POST and correct LAN EEPROM location for clones sscope2ac, sscope2acvd1, sscope2ec, sscope2ecvd1, sscope2jc, sscope2jcvd1, sscope2uc and sscope2ucvd1. Updated PCB info.
- Silverball: Fixed HDD loading. Retire slvrball806 set, use MACHINE_IS_BIOS_ROOT for the base BIOS package. The dump is non-workable, it just crashes strong.
- Striker: Fixed address map. Promoted game to working. Note: This PCB features flying wires going between the Z80, the GM76C28A-10 RAM and a GD74HCT138 3 to 8 line decoder/demultiplexer. It reads 2 times the address 0x60f0/60f1 during RAM test at boot (show "RAM NO GOOD" if wrong value), at coin up and at bet.
- Tiger Road: MSM5205 in clone 'Tora e no Michi (Japan)' is hooked up same as Trojan (capcom\lwings.c) (also tried with capcom\sf.c, but got bad sound).
- Tournament Table: Added PLAYER4 analog direction control defaults (emu\inpttype.ipp) (MT09383).
- Vector games
  . Added LUA bindings for vector-screen interfaces. Added a callback mechanism to expose vector drawing to the LUA interface, allowing external hardware devices to interface with MAME's vector rendering code (video\vector.cpp and mame\luaengine.cpp).
  . Refactored LUA hooks for vector devices (video\vector.cpp and mame\luaengine.cpp).
- WGP: Real Race Feeling: Increased 68000 clock
- Description changes of Beastie Feastie (Pac-Man conversion, set 1), Big Twin (no girls conversion, set 1), BnB Arcade (V1.0005 World), Daytona USA (with Saturn advertisements), Flak Attack (Japan, version P), Flak Attack (Japan, version P, PWB 450593 sub-board), Happy Tour (V1.12), Hot Mind (Hard Times hardware, set 1), Invasion: The Abductors (version 3.0), Invasion: The Abductors (version 4.0), Invasion: The Abductors (version 5.0), Jiao! Jiao! Jiao! (China), Knuckle Bash 2 (bootleg of Knuckle Bash), Mario Bros. (Japan, revision C), Mario Bros. (US, revision F), Major Poker (set 2, v2.0), Major Poker (set 3, Micro Manufacturing intro), Major Poker (set 4, Micro Manufacturing intro), Major Poker (set 5, Micro Manufacturing intro), MX5000 (version R), Nyanpai (Japan), Qianxi Jielong / Hongxin Jielong, Slap Fight (Japan, A76 set, GX-006-A PCB) and Slap Fight (Japan, A77 set, 8606M PCB).
- Fixed rom names in ghosteo.cpp, hominn_980924.cpp, mario.cpp, namcos1.cpp and superqix.cpp
- Renamed (backfirt) to (backfirtb), (gijoea) to (gijoeaa), (majorpkr) to (majorpkr20), (mario) to (mariog), (marioe) to (mario), (mx5000) to (mx5000r), (niyanpai) to (nyanpai), (wgp2) to (wgp2j) and (touryuu) to (touryuua)
- Dipswitch fixes in 4enraya.cpp, igs017.cpp, midwunit.cpp, namcos23.cpp, mario.cpp, (pullttrig) to (pulltrig), tecmo.cpp, niyanpai.cpp and vicdual.cpp
- MAME
  . VIDEO RENDERING SYSTEM
    . Don't use reserved _Names (util\palette.h)
    . Added LUA bindings for vector-screen interfaces. Added a callback mechanism to expose vector drawing to the LUA interface, allowing external hardware devices to interface with MAME's vector rendering code. Refactored LUA hooks for vector devices (video\vector.cpp and mame\luaengine.cpp)
    . Fixed polygons with shared vertices not rendering correctly and correctly map parameter values to each extent (video\poly.h).
  . MEMORY SYSTEM: On switch, do nothing if selected slot is same as before (emu\emumem_mview.cpp).
  . ROMLOAD: Replaced various macros with constexprs and inline functions. Mark ROM_OPTIONAL as deprecated (emu\romentry.h and emu\romload.h). Constexpr at namespace scope implies static for variables and inline for functions (emu\romentry.h).
  . INPUT
    . Don't gate creating input device behind -mouse option, it breaks -mouse_device, -trackball_device, etc (input\input_win32.cpp).
    . Removed barely used IPT_TILT1/2/3/4, combine IPT_GAMBLE_DOOR with IPT_INTERLOCK and rename to generic IPT_DOOR (emu\inpttype.ipp). Added some content for Input Macro and Off-screen Reload plugins (docs\source\plugins\inputmacro.rst and offscreenreload.rst).
    . Added PLAYER4 analog direction control defaults (emu\inpttype.ipp)
  . UI/OSD
    . Added nine extended Latin and IPA characters and added CC0-1.0 license comment (uismall.bdf).
    . Made hide_romless text clearer (ui\submenu.cpp).
    . Limit frame updates on initial gameinfo/warning screens and avoid host CPU/GPU resource spiking (ui\ui.cpp).
    . Added throttled frame update to another startup event loop and sleep for 1ms. Only sleep if no frame update (ui\ui.cpp). Added message if menu is empty (ui\confswitch.cpp).
    . Only clip the cursor if we haven't already. On Windows, cursor clipping is global and needlessly invoking 'ClipCursor(nullptr)' will interfere with other applications that might also be trying to clip the cursor. With this change, MAME will only invoke 'ClipCursor(nullptr)' if MAME previously clipped the cursor (windows\window.cpp).
    . Reverb configuration: Fixed uninitialised data accesses (audio_effects\reverb.cpp). Don't crash on the network devices menu when there are no network interfaces (GitHub #14959) (ui\miscmenu.cpp).
  . PLUGINS: hiscore.dat update (plugins\hiscore\hiscore.dat). Refactored LUA hooks for vector devices (plugins\vector\init.lua + plugins\vector\plugin.json).
  . Consolidate drivers into single file (fantland.cpp, kickgoal.cpp, lethalj.cpp, mario.cpp, rltennis.cpp, segahang.cpp, segaorun.cpp, segas16a.cpp, segas24.cpp, segaxbd.cpp, segaybd.cpp, starcrus.cpp, taito_l.cpp, tecmo.cpp and wgp.cpp)
- SDLMAME
  . Initial support for SDL3. SDL3 is the default for macOS targets. Linux/Windows can build with OSD=sdl3 while we wait for better distro support for SDL3. Both X11 and Wayland sessions are fully supported on Linux. SDL3 -sound=sdl supports both input and output. All other video, sound and input functionality should otherwise be the same for now. SDL 3.4+ multiple keyboard/mouse support is planned.
  . Fixed font lookup (font\font_sdl3.cpp, lib\osdobj_common.cpp). Fixed key up not being sent on some systems. Fixed assert on new instance of joystick connected (input\input_sdl3.cpp). Enable TEXT_INPUT events, fixes text input fields in the UI (sdl3\window.cpp).
- Compiling
  . Small comments cleanup to copy-pasted sprite drawing routines. Lots of ATTR_COLD and some code cleanup.
  . Fixed last remaining tautological compare warnings for Clang/ARM64 (nscsi\tape.cpp and util\ioprocs.cpp). Promoted tautological comparison warning to an error (scripts\genie.lua)
- Debugger
  . Check that you have a memory interface before trying to use it (debugger\win, debugger\osx and debugger\qt) (ID 09377)
  . Allow device_state_interface to participate in global symtable state (debug\debugcpu.cpp and debug\express.cpp)
  . Bulk replace uint8/16/32_t to u8/16/32 (machine\cs4031.cpp, f82c836.cpp, um8498f.cpp and wd7600.cpp)
  . Fixed hang when a watchpoint is hit on a 64-bit wide address space with word addressing (debug\points.cpp)

- CPU
  . Analog Devices ADSP-2100: Correct some tabulaton that had rotted (adsp2100\adsp2100.cpp)
  . Dynamic Re-Compiling
    . drccache: Defer allocating to start, allow forcing W^X mode. Added helpers for allocating structures/objects in the cache. Supply desired alignment when allocating cache memory (not fully implemented). Log some statistics on destruction (cpu\drccache.cpp). Added -[no]drc_rwx option to allow forcing W^X mode when writable executable pages are permitted (emu\emuopts.cpp). Minimise the number of pages that need protection changes. Only mark pages writable starting from the beginning of unused space. Honour requested alignment for allocations (cpu\drccache.cpp).
    . drcbeut: Allocate (misnamed) hash table blocks from the permanent cache area so they aren't intermixed with executable code. Allow back-end to specify preferred alignment for hash table blocks (cpu\drcbeut.cpp).
    . drcbearm64: Shuffled generated code for HASHJMP a bit to be less sensitive to load latency (cpu\drcbearm64.cpp)
    . PowerPC DRC: Allow DRC cache size to be set externally at configuration time, so systems can override the default (cpu\powerpc/ppc.h and powerpc\ppccom.cpp).
    . 3DO DSPP, hyperstone E1-xx + Hynix GMS30C2xxx: Don't allocate DRC resources if recompiler is disabled (dspp\dspp.cpp and e132xs\e132xs.cpp). Simplify arithmetic right shift calculations (e132xs\e132xsop.hxx).
    . ARM7: Removed ARM7 from the list of DRC CPUs since its incomplete recompiler functionality was removed (scripts\src\cpu.lua)
    . Analog Devices ADSP21062 'SHARC'
      . Fixed bug in shift, obvious optimisations: Fixed shift with variable count when count is positive (should shift left, was shifting right). Use recently-introduced UML bit field extract instructions. Don't follow arithmetic with redundant compare to zero if only zero flag is required. Let the back-end take care of fetching source from memory or immediate for simple arithmetic. Assume the back-end knows how to generate conditional CALLH. Use BIT helper. Don't assume x86-like magic sequence breaking on self-XOR. Correct a comment that didn't match the code. Handle corner cases for FEXT. The interpreter probably needs updating, too. Fixed MIN and MAX when Rn and Ry are the same register. Handle corner cases for FDEP. Cleaned up formatting of 64-bit values and initialisation of opcode dispatch table (sharc\sharcdrc.cpp).
      . Fixed SV flag for LSHIFT/ASHIFT in recompiler (interpreter was correct). Simplified generated code for FEXT with non-immediate bit position/length in recompiler. Fixed off-scale ASHIFT in recompiler. Fixed off-scale FEXT with sign extension in interpreter (sharc\sharcdrc.cpp and sharc\sharcops.hxx).
    . UML: Correct syntax for generating UML conditional CALLH instructions (docs\source\techspecs\uml_instructions.rst)
  . Intel 8051: Some variables were missing savestates after OG's refactor (MAME 0.283). Small cleanup to spacing. Clean up some single line comments (mcs51\i8051.cpp).
  . Motorola MC68008: Fixed crash when trying to set PC from debugger (m68000\m68000.cpp)
  . Texas Instruments TMS32xxx
    . Improved naming of TMS320 series DSPs. Name folders after families rather than the first family member emulated by MAME (yes, TMS320C1x and TMS320C2x are retrospective names). Follow TI's convention of including the "C" in the names. Don't try to jam all the disassembler source file names into 8.3. The TMS32010, TMS320M10 and TMS320C10 are different things, but unfortunately MAME hasn't made a distinction between them so far. As far as I can tell, early DECTalk devices used TMS32010 or TMS320M10 chips, while the Atari and Toaplan games used TMS320C10 chips, but this should be verified.
    . Got rid of some superfluous parentheses (tms320c3x\320c3x_ops.ipp). Marked TMS320C31 as parent ROM of TMS320VC33.
  . Zilog Z80: Fixed IRQ state if comes from daisy chain (z80\z80.cpp)
  . Zilog Z80180/Z8S180/Z80182 and Hitachi HD64180RP: Can't shortcut with m_icount=0 after SLP opcode due to possible background Timer/DMA (z180/z180.cpp)
- SOUND
  . Atari C012294 POKEY: Don't flag SEROUT full when held in reset (sound\pokey.cpp)
  . Ensoniq ES5503: Fixed off-by-1 sample position adjustment on looping (Github #14582; sound\es5503.cpp)
  . MM5837 Digital Noise Source: Configuration interface simplifications (sound\mm5837.h)
  . TMS5110: Removed romclk_hack (sound\tms5110.cpp)
- DEVICE
  . Floppy: Minor code cleanup (tools\floptool.cpp)
  . Fujitsu MB87030 SCSI controller: Fixed some timings (drq write would shorten waits) (machine\mb87030.cpp)
  . Imgtool: Retired the get_chain method. This is no longer implemented by any supported filesystem, and no command made any use of the information it provided (floptool's flopblocks command is functionally comparable) (imgtool\imgtool.cpp).
  . Konami 033906 PCI bridge: Added read side effects check (machine\k033906.cpp), should fixes debugger crashes when accessing 0x3500000 in SHARC data space memory in all hornet.cpp sets. Correct k033906_device init order (ID 08830).
  . Namco C123 (4x + 2x Tilemaps): Zerofill control regs (namco\namco_c123tmap.cpp)
  . Sanyo LC7535: Use device_sound_interface. Removed custom volume callback. Added option to use a logarithmic gain scale. Use explictly sized variables (sound\lc7535.cpp).
  . SCSI Hard Disk: Allow to add a per-driver default HD model (still overriden by an IDNT metadata) (nscsi\hd.cpp).
  . VGA: Added imperfect feature graphics where it belongs (video\pc_vga_*)
- New drivers: subsino_kr_h8.cpp
- 1943.cpp: Document and hook up buffered sprite RAM.
- 20pacgal.cpp: Small cleanup. Added screen raw params after Guru measured video timing. Removed useless do_pen_lookup function. Updated notes.

- 3do.cpp
  . Misc notes. Split 'Uncle' in own memory map. Converted 'Madam' and 'Clio' to address_map. Split Madam and Clio into own devices. Split BIOSes by model types, retire original 3do_ntsc/3do_pal romsets. All new dumps provided by [3dodev]. HC-21 is an unreleased USA model. Added kanji region stub for alg sets. Fixed execution for IS_BIOS_ROOT romsets. Preps for VDLP display list parsing, added Amy stub. Hookup Portfolio SWI calls to DASM. Replaced memory_bank with a memory_view for overlay handling.

- cps2.cpp: Don't set sprite priorities before screen_update (ID 09369). Fixed hardware documents.
- cv1k.cpp: Fixed device naming and minor cleanups. Changed ep1c* files filename to cv1k_v*, because this file is emulation core for cave CV1000 hardware specific and more closer to describe actual purpose, also ep1c is part family name of Altera Cyclone (1) FPGAs. Suppress side effects for debugger reads, use logmacro.h for replace plain logerror function. Reduced some duplicates and unnecessary device finder. Make some variables constant. Use reference to replace pointers and util::sext for signed values. Added notes (cave\cv1k_v.cpp). Fixed metadata for describe region. Use shorter typename value for consistency and reduced duplicates. Improved naming and logging. Reduced literal tag usage and unnecessary functions. Added notes (cave\cv1k.cpp).
- cvs.cpp: Lower TMS5100 clock (no xtal). Note: TMS5100 is around 620kHz from an R/C osc with a VR, slightly differs per PCB.
- deco32.cpp
  . Fixed volume control for Dragon Gun and Locked 'n Loaded (ID 05422)
  . Updated Dragon Gun for new LC7535 interface and support switching the gun OKI output between gun speaker and main speaker.

Added N flag for abs opcode and simplify calculation. Accumulator readback is sign extended. Get rid of imultn hack. Make the branch hack confined to CoJag (cpu\jaguar\jaguar.cpp).
  . Stop opcode populates object code too. Correct RMW masks. Regular bitmap rewrite of 16bpp and 24bpp using pitch base. Bump number of object processor max entries to 200, fixes (MESS) jaguar raiden ranking screen and ttoonadv missing gameplay GFXs. Moved out object pointer from process functions. Implemented BCOMPEN, fixes (MESS) jaguar missil3d text and original version GFXs. Implemented pitch in scaled 8bpp bitmap and blending in scaled 16bpp. Partially fixes (MESS) jaguar mutntpng and phase0 main menus, respectively. Avoid potential crash in (MESS) raiden. Fixed object code returns (atari\jagobj.ipp).
  . Attempt to make scanline_update safer. Mask host irqs if correlated bit in INT1 isn't enabled.

  . Added JPIT1 and JPIT2 irq sources, fixes sound in (MESS) jaguar cybermor and mutntpng. Sort out JPIT irq section. JPIT setups needs either prescaler or divider set to work, fixes (MESS) jaguar pbfant sound. Allow changing serial frequency after setting SMODE. Allow playback of BIOS roaring sample. Clear DSP irq lines on JPIT and serial disabled. Extend CoJag Jerry irq hack note (atari\jaguar_a.cpp).
  . Multiply pitch in source and destination widths. Fixed 3D renders for chekflag and others. Improved non-TOPBEN handling. Fixed (MESS) hstrike difficulty select blending and partially fixed (MESS) battlesp main menu. Preliminary GOURZ support. Fixed clipping A1. Shows proper spinning cube in BIOS (atari\jagblit.ipp).
- lethalj.cpp: Added support for savestates
- m10.cpp: Removed screen timing constexpr from class
- model1.cpp: Default NVRAM is 1-filled

- snk.cpp: Added 2 missing save state variables (snk\snk_v.cpp)
- taitojc.cpp: Added wheel_motor for Side by Side and Side by Side 2
- Ace: Improved colors, increased score panel size and added border graphics and confsettings. Small cleanup. Correction to in2 offsets and leave sound triggers unmapped. TODO: Discrete sound is unemulated. What are the unknown inputs in IN2 for? Extra coin sensors? The cabinet does not have a start button. Is the border correct? There's one photo online with gaps in the border. Does it mean planes can fly through at one point, or was it just a PCB malfunction? The flyer shows alternating white/black border objects, but PCB references don't.
- Alien3 The Gun: Added PORT_MINMAX to the Y direction to avoid the value going out of range. Fixes aiming reticle rolls over from top of screen to bottom in alien3, Service Mode shows value for UP goes beyond max FF value back to 00 (ID 08679).
- Amiga/CDTV: Added new CPU 'Sanyo LC6554' MCU core. Implemented front panel with VFD and control buttons. Play/Pause, Stop, Previous and Forward buttons not yet working because the "Remote Control Input Converter" isn't hooked up yet.

- The Simpsons: Changed screen visible width to 320 again after confirming it on a 2nd PCB
- Traverse USA / Zippy Race: Normalize red color channel
- Trivia ? Whiz: Removed 'Trivia ? Whiz (6221-00)'. Note: Same as clone 'Trivia ? Whiz (6221-00, with Sex trivia)'. Added 'Trivia ? Whiz (6221-03, U5-0)' (Merit 1985). Dumped newer program ROMs for Trivia Whiz as well as the question decoder PROM for the Trivia Whiz sets.
- Tropical Angel: Added screen raw params based on M52 and TODO notes
- unknown VRender0+ bowling game: Minor notes update
- Western Venture: Provided good dump for Western Venture (Ver. AA.02.D) program ROMs

- Renamed (dirtdash) to (dirtdashb), (dkongjrv) to (dkingjrv), (packysts) to (packyts) and (revx) to (revx1)
- Dipswitch fixes in 39in1.cpp, goldstar.cpp, koikoi.cpp, royalmah.cpp, shadoww_ms.cpp and snesb.cpp
- MAME
  . VIDEO RENDERING SYSTEM
    . Added an off-screen reload helper plugin for people playing lightgun games with other types of controls (plugins\offscreenreload\*).
    . Make warning msg more generic and brief and put it in a collection(toggle). Added red background and footnote with more verbose msg. No MAME lingo/slang in warning msg (layout\noscreens.lay)
  . LUA engine
    . Better handling of options: Use "classic" locale for numeric conversions. Don't use capturing lambdas. Put integer overload of value() before float overload. Got rid of duplicated numeric options conversion code (mame\luaengine.cpp).
    . Ensuring that 'entry:default_value()' returns the correct type. 'entry:default_value()' was always returning string. A consequence of this problem is that the following LUA commands would error: manager.options.entries['beam_dot_size']:value(manager.options.entries['beam_dot_size']:default_value()) and manager.options.entries['frameskip']:value(manager.options.entries['frameskip']:default_value()). With this change, 'default_value()' will return objects of the correct type (mame\luaengine.cpp).
    . Turn on sol's "safe numerics" (mame\luaengine.h)
  . UI/OSD
    . Added -[no]drc_rwx option to allow forcing W^X mode when writable executable pages are permitted (emu\emuopts.cpp)
    . Shuffled numeric option conversions: Moved float/integer conversions into the option entries themselves. Fixed another bug where float values would be converted to strings with the global local, but converted from strings using the "classic" locale (util\options.cpp).
    . Use "classic" locale for numeric conversions, suppor UI Clear to set default. Note that setting the default just sets the option to its default value at "command line" priority - the options system doesn't support peeling off a layer (ui\submenu.cpp).
    . Start converting "usage" info and comments into new "required_ram" and "required_os" info (Software List; ui\utils.cpp)
  . PLUGINS
    . Fixed Cancel not working in input selection menus (plugins\commonui\init.lua)
    . Added support for non-wrapping analog inputs (plugins\inputmacro\*). Changed the "previous menu" item text to make what it does more obvious (ui\pluginopt.cpp).
    . Removed core off-screen reload hack now that the same thing can be achieved more flexibly with plugins (emu\inputdev.cpp and emu\emuopts.cpp).
  . Better support for external MMUs (emu\dimemory.cpp, emu\machine.cpp, debug\debugbuf.cpp, debug\debugcmd.cpp, debug\debugcon.cpp, debug\debugcpu.cpp, debug\dvdisasm.cpp, debug\dvmemory.cpp, debugger\osx\disassemblyview.mm, debugger\osx\disassemblyviewer.mm, debugger\osx\memoryview.mm, debugger\osx\memoryviewer.mm, debugger\qt\memorywindow.cpp, debugger\win\memoryviewinfo.cpp and m68000\m68000.cpp).
  . Merged wayward speakers (midw8080\mw8080bw_a.cpp, sega\model1.cpp, nscsi\cd.cpp)
  . Set global C++ locale when the standard library isn't broken. GNU libstdc++ only provides a useless stub locale implementation when using anything other than the glibc standard C library. However, llvm libc++ provides a locale implementation that works fine with UCRT. Suppress digit grouping. Too many things don't take it into consideration (osd\windows\winmain.cpp).
  . Use "classic" locale for debug console (emu\debug\*) and ROM loading (emu\romentry.cpp).
- MAC OS X: Apply a default channel mapping for devices where macOS gives no layout information, like MacBook internal speakers. Fixes things being in mono when they shouldn't (sound\coreaudio_sound.cpp).
- Compiling
  . You're supposed to specify MEM_RESERVE when requesting additional address space. This has been buggy since the very first VCS revision of the MAME 0.121 source, but Windows tolerates it (lib\osdlib_win32.cpp).
  . Cleaned up devices build scripts a bit: Lua considers anything other than null or false to be "truthy". The tests against "null" were comparing to a non-existent global called "null" that evaluated to nil. Got bus.lua back in alphabetical order and got at least most of the trigger variables aligned with paths. At least don't put random stuff in the middle of the Acorn devices in machine.lua.
  . Cleaned up some stuff (scripts\src\bus.lua and scripts\src\cpu.lua)
  . Added note about MinGW Clang/LLVM issues with CodeView/PDB symbols at high detail levels (docs\source\initialsetup\compilingmame.rst)
- Debugger
  . Allow "0" to be specified as a parameter for numeric options (tools\unidasm.cpp)

- CPU
  . ADChips SE3208: Cleaned up code in VRender0-related drivers and devices: Suppress side effects for debugger reads. Use snake_case names, use abbreviated integer types and use lowercase hexadecimal digits. Improved logging. Avoid reserved name for type (cpu\se3208\se3208.cpp and se3208dis.cpp).
  . Intel 8086: Effective address calculatation time varies greatly from one (GitHub #14632). CPU variant to the next. On the 286, it's effectively free, unless two additions are required, in which case it takes 1 cycle. On the 8088/8086 on the other hand, it can take up to 12 cycles. There needs to be a different set of timings for each CPU variant. I tested on a 286 system (att6300p) with https://thandor.net/benchmark/36 and the score went from 29 to 46 - almost a 60% speedup! Also added a few minor cycle count fixes (i86\i86.cpp).
  . Intel 80960KA/KB: Clear burst stall on reset (fixes Sega Model 2 games hanging on soft reset) (i960\i960.cpp)
  . NEC V53: Fixed SCU clock selection on V53 and emulated the baud rate generator. Clear m_brc_enable in constructor (nec\v5x.cpp)
- SOUND
  . FM core: Extend at_end FN by 1. Note: (MESS) pc98:metlfrce wants this to detect the speakboard, cfr. note in header card (3rdparty\ymfm\src\ymfm_adpcm.h). ADPCM updates from https://github.com/aaronsgiles/ymfm/pull/40. Fixed endianness and alignment issues when writing WAV files (ymfm\src\ymfm.h).
  . MagicEyes VRender0 Sound Engine: Update per-channel cache when texture memory pointer is changed. Simplify casting (sound\vrender0.cpp)
  . Sound Interface: Sync the speaker streams, fixes the crashing after ~24hours at 48Khz when there is a resampler just before the speaker. Fixed fatalerror when trying to change the sample rate while in stream_update (emu\sound.cpp). Note: Kills g13jnr. Added error for problematic initial sample rates (emu\sound.cpp).
  . Taito Ensoniq Sound System: Re-enable esqpump aux outputs (taito\taito_en.cpp)
- DEVICE
  . Floppy
    . Added support for machines that have non-standard TS (two-sided) line hookups (machine\upd765.cpp)
    . Command interface improvements: Eliminated voluminous info dump on formats and filesystems when invoked with no arguments. Show only usage info for relevant command when parameters are invalid. Added help command to print information about any or all commands, formats and filesystems. Added flopblocks and hdblocks commands to enumerate blocks used by every file or directory on the specified volume (tools\floptool.cpp).
    . Internal API change: Raw pointer accessors (data, rodata) are no longer provided for fsblk_t::block_t. Other accessors used to be based on these methods, but now require their own internal overrides. This entails more copying of data in many cases, but will allow more flexible subclassing opportunities in the future. To compensate for the removal of raw pointer accessors, added methods to fsblk_t::block_t for checking whether a portion of a block is equal to a memory range or a string (eqmem, eqstr). The resulting changed behavior in formats/fs_oric_jasmin.cpp actually fixes a bug in the directory search routine (formats\fsblk.cpp).
  . Hudson HuC6270 VDC: Added AR readback (video\huc6270.h)
  . Imgtool: Fixed error of assigning nullptr to variable of type std::string (imgtool\imgtool.cpp)
  . MagicEyes VRender0 Video Engine: Use templates and function pointer arrays for draw functions. Use device_memory_interface for external memory. Minor fixes in single color fill function. Use pal5bit/pal6bit functions for color field extraction (video\vrender0.cpp).
  . MOS 6551 ACIA: Do not disable the transmitter when a command deasserts RTS. RTS high disables transmitter, but not in the middle of a character (machine\mos6551.cpp).
  . Namco Custom
    . Namco C45 Road + Namco C169 (ROZ): Allow priority/mask value writes in draw routines (namco\namco_c45road.cpp + namco\namco_c169roz.cpp)
    . Namco 186/187 or C355/187 (sprites): Improved flexibility: Use callback for mixing and added transparent pen configuration. Moved alternate precision flag to configuration. Fixed potential crashes. Reduced duplication and unnecessary code (shared\namco_c355spr.cpp).
  . Paradise Systems PVGA1A i/f: Scaffold extended space access (video\pc_vga_paradise.cpp)
  . RAM: Allocate memory with suitable alignment for any type (machine\ram.cpp)
  . SCSI Bus: Added a BSY line callback suitable for drive LEDs to the bus itself (machine\nscsi_bus.cpp). Now all NSCSI users can have a drive activity LED.
  . Seibu Kaihatsu SEI251/SEI252/RISE10/RISE11 Sprite generator: Merged SEI25X and RISE1X sprite hardware emulation into a device. Added configuration option for allocating raw sprite graphics bitmap. Separated plotting logic from sprite loop (seibu\sei25x_rise1x_spr.cpp; seibu\feversoc.cpp, r2dx_v33.cpp, raiden2.cpp, seibucats.cpp and seibuspi.cpp)
  . SoundBlaster 16: Fixed sb16_lle produces ugly beeps in (MESS) ct486 Wolfenstein 3D (ID 09316). Converted irq triggers to input_merger. Moved OPL3 ranges in host_io map. Round up cnt reads to actual raw writes. Ack irq16 too when reading 0x22e from host side. Subscribe to ISA remap. Mode bit 1 is for silence, fixes (MESS) fwmigolf card detection (isa\sb16.cpp). Hookup legacy Microphone level r/w (sound\ct1745.cpp).
  . Western Digital WD33C9x SCSI Controller: Fixed negate ACK should trigger an irq (machine\wd33c9x.cpp, GitHub #14532)
  . Zilog Z80: Skipped memory write in stackless NMI mode (z80\z80n, z80\z80.lst)
  . Zilog Z80 DMA Controller: Relaxed fatal error which were used for unknown commands catching (machine\z80dma.cpp)
- aleck64.cpp: Set up more stuff at construction (nintendo\n64_v.cpp). Got rid of unused private field (nintendo\rdpblend.cpp/h).
- armedf.cpp
  . Terra Force: Correct offset for marking dirty tile. Fixes the left and right sides of the image are cut off in the title demo scene (ID 09326). Increased spriteram size. Fixes sprites may disappear during attract mode (ID 09327). Correction to blitter_txram_w dirty mask for clone Terra Force (Japan, bootleg with additional Z80).
  . Correct FM sound chip type (armedf and terraf) (ID 09328) (ID 09329)
- balsente.cpp: Allow self-oscillation when no waveforms are enabled (sound\cem3394.cpp)
- brkthru.cpp: Increased screen width and rearranged comment block. Put bgscroll write in its own function and correct clone Break Thru (Tecfri license) coinage dipswitch. Update notes. Added 'Flip Screen' dipswitch. Small cleanup. Correct continue/servicemode dsw for brkthru. Correct interrupt logic.
- cdi.cpp: Fixed Letterboxing in (MESS) CD-i 'Mystic Midway - Rest in Pieces' (GitHub #14694) (philips\mcd212.cpp) (philips\mcd212.cpp).
- chihiro.cpp: Added dsp563xx unit tests (virtual driver utdsp563xx). Correct a couple of dsp563xx instructions and added the opcode to the display. Fixed regression in determining operating mode (cpu\dsp563xx\dsp563xx.cpp).
- cps1.cpp: Dumped PLD for clones area88r and cawingjr
- crospuzl.cpp, crystal.cpp, ddz.cpp, menghong.cpp, psattack.cpp, trivrus.cpp and v0bowl.cpp: Cleaned up code in VRender0-related drivers and devices: Suppress side effects for debugger reads. Use snake_case names, use abbreviated integer types and use lowercase hexadecimal digits. Improved logging.
- deco32.cpp: Fixed save state support, added context to logging and cleaned up code.
- firebeat.cpp: Added the SWP30 to the list of drc-using CPUs (scripts\src\cpu.lua)
- gaiden.cpp: Make tile scrolling consistent with hardware. Added missing x offset registers for the tile layers. Use set_scrolldx/y to set the x/y offsets for the tilemaps. Adjust x/y offset logic so it matches up with what happens on hardware.
- gal3.cpp, namcofl.cpp, namconb1.cpp, namcos2.cpp, namcos21_c67.cpp and namcos21_de.cpp: Use abbreviated integer types consistently. Use single-pass C355 draw routine.
- galaxi.cpp: Templates, hopper device instead of custom implementation.
- gamtor.cpp: Improved hardware documentation. Fixed format and small typos. Added DIP switches.
- goldstar.cpp
  . Cleanup cmast97 and jpknight dipswitches
  . Consistent naming for more DIP switch settings. Also order payout rate settings from least to most generous and key-in is not coins.
  . Removed leftover, cleaning up Mega Lines and Skill Chance screen update.
  . Added 'Double Up Game' and 'Check Account (Allow Books)' dipswitches to cherry96, cherry96a, cherry98 and cherry98a. Also added the game version to cherry96 and cherry96a game descriptions.
  . Clone Cherry Bonus III (Ivanhoe V46-0799) improvements: Workaround to skip the 240 games suicide limit. Added dsw settings.
  . Fixed A-Plan foreground graphics and reels graphics bitplanes order
  . Cherry Master '99 (QL-1 V9B.00) improvements: Created new dedicated machine config, memory map and basic raw inputs. First attempt to implement the weird and complex dynamic ROM banking, that now allows the game to boot and play the attract. Fixed bug in the Cherry Master '99 bank selector. Improved inputs and added buttons-lamps control panel to cmast99 and cmast99b. Fixed one bad bit of cmast99 and cmast99b reels graphics. Added extended PLD dumps to cmast99 + clones and texas99 sets. Added technical notes about the insane bankswitching for this hardware. Sharing the same Cherry Master 99 regular PLDs with the cmast99 and texas99 sets. Cherry Master '99 (QQ-1 V9B.00, bootleg) improvements: Applied same machine and scheme than the original Dyna parent.
  . Extended the Cherry Master 99 extra bankswitching PLDs to top7, top7a and war3cb sets. All running in the same hardware base. Removed the bad dump flag to the top7 and top7a sets bipolar PROMs. Confirmed that they are identical to the Cherry Master 99 ones. Sharing the same Cherry Master 99 regular PLDs with the top7 sets and war3cb.
  . Reorganized Dyna El Dorado sets by hardware (Dyna D9101, D9105 and D9106C PCB)
  . Added nfb96 conditional DIP switches for payout rate/difficulty display (DSW1). Implemented conditional nfb96 DIP switches behavior for DSW1 based on DSW4:2. When "Show In Confirm Screen" (DSW4:2) is set to Percentage, DSW1 now displays payout rate values (55%-90%). When set to Level of Difficulty, DSW1 instead displays levels (1-8). Both sets of options use the same bitmask (0x07) and are filtered through PORT_CONDITION to match the hardware behavior.
  . Fixed all remaining Wild Cat 3 animations
  . Added handcrafted Dallas (ds2401_50.bin) iButton data to fl7_1000, fl7_2000, fl7_2k16, fl7_50, fl7_50_gs01, fl7_50_gs02, fl7_50_gs03, fl7_50_gs04, fl7_50_gs05, fl7_50_gs06, fl7_50_gs07, fl7_50_gs08, fl7_500, fl7_tw and fl7_twa. Removed the hack toward the accurate emulation. Renamed the device ROMs to DS1994L-F5. Added technical notes about DS1994 against DS2401 for Flaming 7's custom hardware. Updated Cyberdyne Systems Flaming 7's technical notes about emulation status and Dallas ibutton serial number.
- hng64.cpp: Added lamp and ffb wheel outputs. Hooked up the second address space selected by /ROM pin 86 (sound\l7a1045_l6028_dsp_a.cpp). Adapted to use the ROM address space and turned off logging.
- igs017.cpp: Support control panel for starzan, tarzan103m and clones. Marked tarzanc and starzan + clones not working due to protection issues (ID 09197).
- model2.cpp
  . Tidy some stuff (sega\model2_v.cpp, sega\model2rd.ipp). Replaced a macro with a constexpr function (sega\model2rd.ipp).
  . Various improvements: Moved geo_parse() and frame number update to start of vertical blanking (fixes high score scrolling in segawski, 2D palette in dynamcopc, and 3D graphics in bel not displaying after first booting up). Use exponent to adjust the Z-value scale for Z-sorting. Merged model2_3d_process_quad() and model2_3d_process_triangle() into a single template function, since most of the code was identical. Original Model 2 does have FIFO control; it uses the same 315-5673 buffer controller as Model 2A and 2C. Replaced scanline timer with vertical blanking callback (sega\model2.cpp, sega\model2_v.cpp). Fixes shot enemies and burning cars skeletons flickering colour is a strange pink/magenta like in vcop2 (ID 09287).
  . Intel 80960KA/KB: Clear burst stall on reset (fixes Sega Model 2 games hanging on soft reset) (i960\i960.cpp).
  . Hooked some more lamp outputs based on SailorSat's work.
  . Added default backup RAM and EEPROM content for Hanguk Pro Yagu 98. Also correct texture ROM loading. The game now boot and runs.
  . When writing to IRQ mask register, wait two cycles before checking for sound IRQ. Fixes music missing in beginner stage of Virtua Cop 2 (sega\model2.cpp) (ID 09313).
  . Use object finder and suppress side effects for GTX protection handler
- namcos2.cpp: Use abbreviated integer types consistently. Use single-pass C355 draw routine. Split driver state classes for different hardware configurations. Optimized drawing slightly. Improved ROM region names, updated notes, and cleaned up code (namco\namcos2.cpp). Use priority mechanism rather than multiple drawing passes (namco\namcos2_roz.cpp, namco\namcos2_sprite.cpp). Added priority value and mask parameters to drawing functions, and cleaned up code (namco\namcos2_roz.cpp). Added priority value and mixing callbacks. Draw sprites in a single pass using priority control. Cleaned up code and updated notes (namco\namcos2_sprite.cpp).
- namcos10.cpp: Move rate changes outside of stream update (sound\lc82310.cpp). Fixed fatalerror when trying to change the sample rate while in stream_update. Note: Kills g13jnr (ID 09292). Source style cleanup (sound\lc82310.cpp).
- namcos12.cpp: Ensure m_regs is initialized and saved (machine\icd2061a.cpp)
- namcos22.cpp: Hook up System22 outputs, based on SailorSat's work.
- nwk-tr.cpp and zr107.cpp: Wheel FFB outputs hooked for racingj, racingj2, thrilld and zr107.cpp.
- seattle.cpp: Standardize rom loading structs. Removed 'BAD_DUMP' flag for seattle.snd. Sound subsystem test in mame and pcb matches. This alone convinces me to remove that flag.
- sfbonus.cpp: Updated driver. Verify initial hardware-board compatibility for several game sets. Performed three passes of validation to confirm which game sets successfully boot on specific PCB types. This update documents the initial compatibility findings and lays the groundwork for more detailed hardware-mapping in future revisions.
- starwars.cpp: Difficulty settings in Star Wars now match the arcade operator's manual (starting shields: 6, difficulty: Hard). Difficulty and Demo Sounds in 'The Empire Strikes Back' can't be inherited from starwars as they are scrambled/inverted relative to starwars. Difficulty default ("Hard") taken from ESB Conversion Kit manual.
- vegas.cpp: Shuffle set versioning around. Changed warfa and nbanfl to use the different bootroms as BIOS options. Removed patch for nbanfl. Removed warfac set (only bootrom different vs. parent set).
- Arch Rivals: Added a PLD dump
- Backgammon: Use English DIP switch setting labels
- Balance Try: Hookup input, sound and NVRAM.

  . VIDEO RENDERING SYSTEM
    . Fixed PowerPC build (video\rgbutil.cpp)
    . Improved accuracy and performance calculating text aspect ratio (emu\rendlay.cpp). Also added another text alignment option to stretch the text to fill its bounds horizontally. The current code calculating the aspect ratio for text involves looping, calculating the width of text for a variety of decreasing aspect ratios until the text's width is less than the available bounds. However, this string width calculation performs the same loop over the text each time, finally multiplying by the candidate aspect ratio. That text width calculation thus really only needs to be done once. Further, instead of trying different aspect ratios, the ratio can simply be calculated directly by dividing the width of the bounds by the string's width. This also calculates a more accurate aspect ratio, rather than always resulting in an aspect ratio of (0.95)^n. For example, when trying to fit a 101-pixel wide text into a 100-pixel wide space, the current code would result in an aspect ratio of 0.95, making the text 96 pixels wide,  leaving 4 pixels unused;  the new code will instead calculate the aspect ratio as 100/101 == 0.9900990099... , making the text use the full 100 available pixels. This in turn allows us to easily calculate the ratio also if we want to not just schrink but also stretch the text to fill the available space, so we add that as another text alignment option, number 3 (three). This PR also demonstrates this in the VFX family of layouts, where on the default Full view, the text "MUSIC PRODUCTION SYNTHESIZER" ("DYNAMIC COMPONENT SYNTHESIZER" on the VFX), the logo-like text "ensoniq", and the keyboard-specific markers "VFX", "VFX-SD", "SD-1" and "3 2 V O I C E" can now be made to fill their available space horizontally as they should, making it all look that much more like the real thing. Fixed text clipping introduced by https://github.com/mamedev/mame/pull/14550. Guard against possible divide by 0 (emu\rendlay.cpp). Got rid of syntax that definitely isn't supported from layouts (emu\rendlay.cpp).
    . Added artfont option for changing default font of .lay files text elements. Fixed text align issues with wide width font (emu\emuopts.cpp and emu\rendlay.cpp)
    . Replaced use of slash/backslash text for diagonal lines with SVG (layout\*)
  . MEMORY SYSTEM: Allocate memory region storage with suitable alignment for any type, added length accessor to and removed machine from memory region (emu\emumem.cpp).
  . LUA engine: Access machine.side_effects_disabled. Refactored machine:side_effects_disabled() as a method instead of property (mame\luaengine.cpp).
  . UI/OSD: Added speaker channels to gameinfo panel (ui\info.cpp)
  . Correct .lay files with text alignment issues on Linux (layout\*.lay)
  . Added 'tag' attribute to Info XML '' elements. Added entry in DTD for '' (mame\infoxml.cpp).
  . Reduced some of the short name inflation. It's getting silly, some of the short names are close to the length limit, which prevents forming clone names by adding suffixes. I raised my concerns about the possibility of short name inflation when I relaxed the limit. It looks like it wasn't unfounded.
- Compiling
  . Avoid passing -m flags for pointer size on 64-bit RISC-V Linux (makefile)
  . Fixed a considerable number of things that give -Wcast-align warnings in src/mame. There are still far more.
  . Fixed a number of endianness issues.
  . Use multibyte.h helpers instead of playing fast and loose with alignments (emu\save.cpp, util\png.cpp, various disk and cassette formats)
  . Got rid of almost all remaining uses of driver_data (mame\*) and of long-obsolete driver_data (emu\machine.h).
  . Tidy some stuff (mostly LlamaCase template parameters and fewer temporary strings) (sound\adc.cpp and sound\swp30.cpp)
  . Use raw string for pattern match (scripts\build\check_include_guards.py)

  . Intel 80186: Added latency when writiing DMA registers before the next DMA starts. Fixes (MESS) MPC60 crashing and the other drivers using a '186 all behave identically to 0.280 (i86\i186.cpp).
  . Intel 8257 DMA Controller: Make the driver handle verify cycles since the DMAC only does an address strobe (machine\i8257.cpp)
  . Intel I386: Set CPl after all memory reads are done in i386_task_switch (i386\i386segs.hxx)

    . Documented all of the upd72069 auxiliary commands. Added Control Port C4 and C6 outputs for TC8566AF. Allow invalid auxcommand sent by (MESS) S3000, which works on hardware (machine\upd765.cpp).
    . Added support for bad address field crc in basic fm and mfm images (formats\flopimg.cpp)
  . Gaelco DS5002FP: Cleaned up (gaelco\gaelco_ds5002fp.cpp)
  . MB89371 Dual Serial UART: Rewrite MB89371 as a fully functional device (machine\mb89371.cpp)
  . MC68681 DUART: Added received data to FIFO in loopback mode (machine\mc68681.cpp)
  . PC hardware: Fixed up a few things for later PC models. The emulation of these systems still isn't very good in general (machine\genpc.cpp)
  . RS-232 Null Modem: Improved text transmission options: Added configuration switch to translate CR/LF characters from the bitbanger input prior to transmission. Multiple translation modes are provided. Added configuration switch to delay further transmission for a number of milliseconds after each CR is sent (rs232\null_modem.cpp).
  . Ticket Dispenser: Added a sensor test input for convenience. Also call the line status callback for ticket dispensers as well as hoppers and cleaned up the code a little (machine\ticket.cpp).
- balsente.cpp: Improved CEM3394 and adapted sente6vb to the changes. Added and improved CEM3394 functionality relevant to the (MESS) 'sixtrak' while working on audio for that. Sending as a separate PR to keep the scope manageable, given there are also changes to 'sente6vb'. Incidental improvements to 'sente6vb': "unlocked" some sounds. An obvious one is the post-tuning chirp for each voice during boot. Centered audio around 0. CEM3394 changes: Made VCO output range [-1, 1], instead of [0, 1]. Added pulse-width dependent DC level of pulse waveform, as described in the datasheet. Waveform selection logic now works for voltages outside the bounds provided in the datasheet. Both the (MESS) sixtrak and sente6vb will some times use voltages outside those ranges. Added AC coupling between VCF output and VCA input. Forcing parameter computation in device_start(). Added ability to stream voltage inputs. The (MESS) sixtrak needs that for the VCA gain and VCF frequency. New configuration interface: New configure() method computes VCO and VCF zero frequencies based on the attached passive components. Exposed method for enabling pulse-width limiting for drivers that need it. Now disabled by default. Fixed compilation for FILTER_TYPE_ESQ1. sente6vb changes: Using new CEM3394 configuration interface. Verified that it produces almost the same VCO and VCF zero frequencies. Reduced CEM3394->speaker gain to compensate for increased loudness of CEM3394. Old range: [0, 1]. New range: [-1, 1]. Added AC coupling to noise output. Also changed the noise->CEM3394 gain from 0.5 to 1.0, so that the relative loudness remains the same. Old range: [0, 1] x 0.5 = [0, 0.5]. New range: [-0.5, 0.5] x 1. Fixed "FREQENCY" typo and updated comments (sound\cem3394.cpp).
- bfm_ad5sw.cpp and bfm_sc5sw.cpp: Provide MBAR relocation and GPIO reads to MCF5206E CPU, fixes all games crash at start (ID 09270).
- cdi.cpp: Fixed XA audio peaking by decoding in 32-bit and clipping to 16 later (philips\cdicdic.cpp). Simplified mouse position-update logic (philips\cdislavehle.cpp). Cleaned up (philips\cdicdic.cpp).
- chihiro.cpp: Added DSP56362 to the audio processing unit in shared\xbox_pci.cpp as the general purpose DSP
- cps1.cpp: Use three buttons per player for Final Fight (ID 09294). Note: The third button connection is always wired on the CPS-1 mainboard and does work in the game, even if it's an undocumented easter egg. In many cases, the board sets were installed in generic JAMMA cabinets with standard stick plus three buttons control panels, allowing players to use the third button. Final Fight button 3 is not officially documented and does not exist on the control panel, probably a leftover. Pressing it will allow you to escape from grabs and choke holds instantly. To access the hidden pattern test modes, turn the "Service Mode" dip to ON and hold down "P1 Button 1" ('Ctrl') or "P1 Button 2" ('Alt') during the bootup test. Button 1 will load the Scroll (Background) test and Button 2 will load an Obj (Sprite) viewer.
- cps3.cpp: Provide an hack free status read (machine\wd33c9x.cpp)
- goldstar.cpp

Fixed the rom load of clones nfb96se, nfb96sea, nfb96seb, nfb96sec, carb2002 and carb2003 taking care of the proper graphics bitplanes. Removed the imperfect color flag of the above games. Marked clone carb2003 reels graphics ROMs as bad dump. Flagged the game as imperfect graphics. Temporal workaround bypassing some checks for clone noved.
  . Super Cherry Master bootleg hardware improvements: Added 0Ch and 0Dh missing ports, hooked remaining DIP switches banks. New inputs from the scratch for New Cherry '96 and base for New Cherry '98. Switched the New Cherry '96 sets to this machine. Added buttons-lamps control panel layout.

  . Fixed textured mesh polygons. Need to double all the increment values (sega\model2rd.ipp).
  . New trilinear implementation, runs about 40% faster. Added support for microtextures (sega\model2_v.cpp and sega\model2rd.ipp). Pre-bind render callback delegates (sega\model2_v.cpp).
  . Limit microtexture blend factor to 127/256. Prevents microtextures being drawn when the base texture is transparent, fixes wallpaper in hotd (sega\model2rd.ipp).
  . Draw polygons front to back, use fill buffer. The real hardware has two 32Kx8 RAM chips described in the Model 2B manual as "fill memory"; these effectively function as a pair of 1-bit depth buffers, one for each framebuffer. Performance is improved over back-to-front rendering, particularly in more intensive scenes, since pixels that would be drawn where other pixels have already been drawn can be discarded early before texture mapping is performed.
  . Tilemap fixes: If all three layers (polygon, tilemap A, tilemap B) are transparent, palette entry #0 from tilemap B is shown (sega\model2_v.cpp).
  . Apply color table to tilemap layers, INDY 500 supports 16:9. Also use correct CRTC offset values when drawing directly to the framebuffer (sega\model2.cpp, sega\model2_v.cpp).

  . Fixed init_cdsystem return command and added get_cddevice_connection command (sega\stvcd.cpp). Cleanup function and variable namings (sega\stv.cpp). Port over QA notes from GitHub #8919 (sega\saturn_v.cpp).
  . Removed device_memory_interface and fixed open bus access (sega\smpc.cpp).
- Buck Rogers: Verified ROM labels and locations for clone Buck Rogers: Planet of Zoom (not encrypted, set 1)'s program ROMs.
- DT7 (prototype): Correct G_59 opcode for DT7 sound CPU (toaplan\toaplan_v25_tables.h)

- Bob Zed (What's new): https://youtu.be/60y20tKb9F4
- CPU
  . DEC T11
    . Handle unaligned accesses to I/O page. Certain devices on bk, uknc require this, as they do not handle the WTBT bus signal and always decode full address (t11\t11.cpp).
    . Improved interrupt handling in K1801VM1 CPU core. Added interrupt processing and EIS instructions to K1801VM2 core (t11\t11.cpp).
  . Dynamic Re-Compiling
    . drcbec
      . Fixed code for ROLC that played fast and loose with integer promotion, producing incorrect results for some compilers/targets (cpu\drcbec.cpp).
      . Fixed default floating point rounding mode not applying after RESTORE (cpu\drcbec.cpp).
    . drcbex86
      . Clear the zero and carry flags for unordered floating point comparisons for consistency with the documentation and the other back-ends (cpu\drcbex86.cpp).
      . Mask flags when setting via SETFLGS or RESTORE to avoid possible buffer overrun, slightly optimised SETFLGS with an immediate operand. Optimised FCMP when only the unordered flags is required (cpu\drcbex86.cpp).
      . Optimised GETFLGS: LEA to avoid the need to save/restore flags for more flag combinations, choose registers more wisely to avoid unnecessary copies and reduce REX prefixes, use more efficient strategy to save and restore flags. Removed assert that made SETFLGS impossible to use in debug builds. Removed casts that are no longer necessary (cpu\drcbex86.cpp).
    . drcbex64
      . Clear the zero and carry flags for unordered floating point comparisons for consistency with the documentation and the other back-ends. Slightly optimised flag calculation for some shifts and rotates (cpu\drcbex64.cpp).
      . Simplified and ptimised flag calculations for rotate instructions (cpu\drcbex64.cpp)
      . Mask flags when setting via SETFLGS or RESTORE to avoid possible buffer overrun, slightly optimised SETFLGS with an immediate operand. Optimised FCMP when only the unordered flags is required (cpu\drcbex64.cpp).
      . Avoid slow microcoded pushfq/popfq altogether. Also avoid some false dependencies and reduce near cache usage by almost 4KiB (cpu\drcbex64.cpp).
      . Optimised a couple more cases of GETFLGS and replaced a few magic numbers with constants. Use 2-operand and 3-operand forms of imul. Also changed scratch register use a bit. Optimised MULU/MULS flag calculation. Removed assert that made SETFLGS impossible to use in debug builds. Removed casts that are no longer necessary (cpu\drcbex64.cpp).
    . drcbearm64
      . Use bfxil to save an instruction for smae cases of CARRY and ROLINS (cpu\drcbearm64.cpp)
      . Fixed default floating point rounding mode not applying after RESTORE. Optimised generated code for SETFLGS a little (cpu\drcbearm64.cpp).
      . Save an instruction when calculating carry flag for shifts with immediate count. Optimised MULU/MULS flag calculation. Handle degenerate forms of ROLAND/ROLINS when simplifier is disabled. Removed assert that made SETFLGS impossible to use in debug builds (cpu\drcbearm64.cpp).
      . Further optimised 32-bit multiplication and flag calculation for all multiplication instructions. Fixed 32-bit SEXT sign extending to 64 bits. Removed casts that are no longer necessary (cpu\drcbearm64.cpp).
      . Don't try to get offset of unbound labels even if it won't be used (cpu\drcbearm64.cpp)
    . ST0016: Moved ROM banking from drivers into device. External ROM is now read through an address space. Also reduced literal tags, suppress side effects for debugger reads and cleaned up code.
    . UML: Truncate immediate operands for CARRY (cpu\uml.cpp). Marked BREAK as clobbering all flags and marked LOAD, LOADS, STORE, SET, FLOAD and FSTORE as not modifying flags. CPUs already depend on SET not modifying flags (cpu\uml.cpp).
    . PowerPC drc: Generate a simpler multiplication opcode for MULLI (powerpc\ppcdrc.cpp)
    . x86/x64 code logging helpers: Encapsulated as a class, don't use unsafe sprintf, optimised a little, made comments and data ranges vectors (cpu\x86log.cpp).
    . Doc: Documented the last of the UML instructions (docs\source\techspecs\uml_instructions.rst)
  . Hitachi HD63705Z0: Use logmacro logging (m6805\hd6305.cpp)
  . hyperstone E1: Optimised generated code for multiplication and DSP instructions a little. Fixed recompiler not sign-extending EHMAC inputs (interpreter was correct) (e132xs\e132xs.h, e132xs\e132xsdrc_ops.hxx).
  . Intel 8086: Avoid clearing working registers upon device reset (i86\i86.cpp). Note: This change is required in order for BIOS for the AT&T 6300 Plus to work. The 6300 Plus has external logic to reset the 80286 via the reset pin, so that it can return to Real Mode from protected mode. Upon return to Real Mode, the BIOS code is clearly depending on the fact that SP register is preserved upon reset (the BIOS does however explicitly load the SS register after reset, before it is used). The 8086 and 80286 documentation call out which registers are to be initialized upon reset, and SS is one of them. For AX, BX, CX, DX, BP, SP, SI and DI, the behaviour is not specified. However, based on what the 6300 Plus BIOS is doing, it appears the actual hardware behaviour is to leave them untouched. Although we can only be fully confident that the real 286 behaves this way with respect to the SP register, it's likely that the other registers which do not have explicitly defined initialization behavior are also not touched during reset. Note that this observed behaviour only pertains to reset via the reset pin, and not to power-on initialization.
  . Intel 80960KA/KB
    . Only trigger interrupts if the input changes to the asserted state (i960\i960.cpp). logr and logrl use base 2 and always use correct rounding mode (i960/i960.cpp).
    . Split check_irqs() into two separate functions, fixes "Fatal error: I960: 2f2f2f2e: Unhandled 00" during Self-Test in vf2o, overrev and sgt24h (ID 08347). Pending interrupts are only checked after returning from an interrupt, while executing modpc if it causes the current priority to be lowered, and after receiving a test pending interrupts IAC message (i960\i960.cpp).
    . Fixed typo in ROUNDRL instruction (i960\i960.cpp)
  . MCS-51
    . Fixed destination RAM type in XCHD A, @R0/@R1. The initial value is read from internal RAM (IRAM_IR). The final value must be written to the internal RAM too (IRAM_IW instead of IRAM_W) (mcs51\mcs51ops.hxx).
    . Renamed the external data bus from io to data. Start turning the internal maps into real maps. Modernization step 1+2 (mcs51\mcs51.cpp)
  . NEC uPD7810: Added internal layout and complete driver implementation for (MESS) Roland PG-1000 (upd7810\upd7810.cpp, roland\roland_pg1000.cpp)
  . Texas Instruments TMS7000: Clean up code in disassembler (tms7000\7000dasm.cpp)
  . Toshiba TMP95C06x: Fixed uninitialised members. Also got a lot of stuff out of the header that doesn't need to be there (tlcs900\dasm900.cpp). Show SFR symbols in disassembled code for names for TMP95C061, TMP95C063 and TMP96C141.
  . Zilog Z80: Cleaned up unnecessary internal state validation (SA_BUSACK) which caused INT skip (z80\z80.cpp)
- DEVICE
  . 8042 Keyboard/Mouse Controller: Can't possibly receive if the timer isn't running. Fixed PCIAGP boot without debug tricks (machine\8042kbdc.cpp).
  . Flash ROM: Added ST_M29W640FT and implemented unlock bypass command. Support for Winbond W29C020C + preliminary Winbond SDP mode (machine\intelfsh.cpp)
  . Floppy
    . Support quad density floppies as an option. Disable option ROM on fixed disk controller (onboard BIOS has built-in support). Use a lambda instead of short function (isa\fdc.cpp).
    . Added rudimentary error checking to floppy_create, allow mount to return nullptr on failure. Fixed error return for floppy_create (tools\floptool.cpp, tools\image_handler.cpp). Sanity check for debug builds (formats\fsblk_vec.cpp).
    . Added 8bit DMA and NOP unknown FDC commands to (MESS) MPC-3000 (machine\upd765.cpp). Added uPD72069 data rate control (machine\upd765.cpp)
    . New filesystem-based commands: Added flophashes and hdhashes commands to compute CRC-32 and SHA-1 hashes for each file on a floppy or hard disk image. Added flopchmeta command to change the metadata for a file, directory or volume on a floppy image. Added floprename and flopremove commands (tools\floptool.cpp).
  . Hitachi HD44780 LCD Controller: Reorganized the classes so that the a0* bad dump do not propagate to systems not using it (video\hd44780.cpp). Removed the parent roms stuff because we do not have a parent concrete device anymore (video\hd44780.h).
  . IGS017_IGS031: Don't hardcode tilemap ROM size in decryption function (igs\igs017_igs031.cpp), fixes 'Krazy Keno' which has bigger ROM [Osso].
  . Intel 8259 PIC: Side effect protection
  . ITE IT8705F LPC Super I/O: Fixed FDC DRQ line setup. Hookup ISA DMA bindings (machine\it8705f.cpp).
  . Konami 056832 Tilemap Generator: Got rid of a redundant function with duplicated code (konami\k054156_k054157_k056832.cpp)
  . NMK112: Use configured banking rather than writing to ROM regions. Handle non power of two ROM sizes properly (machine\nmk112.cpp).
  . NVRAM: Removed DEFAULT_RANDOM init (machine\nvram.cpp)
  . RS-232 Port: Added option for (MESS) Heath H19 terminal. Changed to the option function to a static method.
  . SEI80BU Encrypted Z80 Interface: Moved SEI80BU emulation into its own source file (seibu\sei80bu.cpp). SEI80BU is not always part of the Z80-based sound system, e.g. seibu\mustache.cpp. Also added input frequencies for SEI80BU devices (uses the same clock as the Z80).
  . Seta ST0020/ST0032 Sprites: Made ST0020 and ST0032 separate devices. Use util::sext for sign extension. Suppress side effects for debugger reads, use logmacro.h for configurable logging (seta\st0020.cpp).
  . SiS 950 LPC Super-South Bridge: Hookup ISA DMA bindings (machine\sis950_lpc.cpp)
  . Taito TC0110PCR: Use callback and configuration for color format and address shift. Also use logmacro.h for logging and suppress side effects for debugger reads (taito\tc0110pcr.cpp).
  . Toaplan Text tilemap generator: Merged common text layer emulation in GP9001-based drivers into a device (toaplan\toaplan_txtilemap.cpp)
  . Winbond W83977TF Super I/O: Hookup FDC, GPIO1, FDC irq and drq lines. Ensure Super I/O port to be installed after the others. Hookup ISA DMA bindings and fixed floppy fails (machine\w83977tf.cpp).
  . Z80 CTC: Improved interrupts handling in (MESS) specnext (machine\z80ctc.h)
  . Zilog Z80 DMA Controller: Always return live status regardless of when read command was sent (ID 09143). Refactor read register emulation. Minor logging refinements and cleanups (machine\z80dma.cpp). Keep member declarations together (machine\z80dma.h).
- SOUND
  . Ensoniq 5505/5506 to 5510 interface: Route es5505 bus to a separate 'aux' stereo output. The VFX-SD and later keyboards in the family have not only a main stereo output, but also a second 'aux' stereo output that bypasses effects processing and has separate output jacks from the keyboard. This allows some sound to be routed for separate effects processing or recording (sound\esqpump.cpp and ensoniq\esq5505.cpp).
  . Ensoniq ES5505/6: Devices generate 20bit samples, not 16-bit ones.
  . Yamaha SWP30 sound chip: Overhaul. Use util::sext and explicit specializations for std::clamp and std::min. Removed crashing debug fopen/fprinf and srcclean (sound\swp30.cpp)

Adjusted final mix to capture the true highest bits, don't retrigger the filter envelope on writes and decode the loop parameters. More plausible loop point calculation. Updated documentation. Further work on loop parameters. The crowd in Xtreme Rally now sounds reasonable. Additional cleanup, proper logging, device map and multichannel output. Also changed owners/licensing given extensive rewrite since 0.280. Added DMA support. 16-bit linear sample format supported. Remap the channel mapping to make sense. Better logging. Cleanup, improved logging, fixed missing address mask, fixed issue with 16-bit playback and added enum for output channels. Make into a device_memory_interface with a side of memory_access cache (sound\l7a1045_l6028_dsp_a.cpp).
  . Improved MIPS/V53 communications, fixes many problems with Xtreme Rally. Spin the MIPS for the actual required time to prevent overruns, which is much lower (snk\hng64.cpp).

  . Unoptimized preliminary support for mipmaps and trilinear filtering: Bilinear luma filtering for SEGA Model 2 textured render path. Bilinear improvements discussed on pull request thread. Code standard. Anti Alpha higlighted edges ala Supermodel. Cleaner bilinear edge cases ala Supermodel (sega\model2_v.cpp, sega\model2rd.ipp). Added dpdy information to extents to be able to compute mipmap lod index per pixel (video\poly.h). Added all mipmap information to m2_poly_extra_data structure (sega\model2.h, sega\model2_v.cpp). Added preliminary unoptimized support for mipmaps and trilinear filtering. Fix to code overflow error in transparent trilinear. Converted render callbacks to C++ member function templates (sega\model2rd.ipp).
  . Improved interrupt logic: Interrupt control register only returns interrupts actively signalled to the i960; masked interrupts are not returned. Sound IRQs are triggered when either TxRDY or RxRDY from the USART is active (Model 2B manual, section 6.2). Removed model2c_interrupt callback; no evidence that Model 2C behaves any differently to earlier board revisions. Removed vcop issue from TODO list since it no longer occurs (tested) (sega\model2.cpp).
  . Correctly combine sound USART interrupts. Make sound_ready_w() protected; read status from USART instead of tracking state using member variables. Reduced number of render delegates (sega\model2.cpp).

- nss.cpp, sfcbox.cpp, snesb.cpp and snesb51.cpp
  . Fixed status flag display in emulation mode. In emulation mode, "MX" are " B". Both bits are always 1, only the semantic meaning changes: " " doesn't exist, and "B" is only meaningful when pushed during an IRQ/NMI, to distinguish from BRK (g65816\g65816.cpp).
  . Fixed IRQ to be level triggered. Followup b3f2535: stop clearing LINE_IRQ when jumping to the IRQ vector. Properly written IRQ handlers won't notice any difference, but this fixes the behavior for software which (possibly intentionally) fails to clear an IRQ source; in that case the IRQ should continue to trigger (probably leading to a system hang). LINE_SO is generally not hooked up, but if it is, it doesn't raise IRQ. Also delete unused G65816_INT_* macros (g65816\g65816.cpp).

- MAME
  . VIDEO RENDERING SYSTEM
    . Polygon rendering: Added dpdy information to extents to be able to compute mipmap lod index per pixel. Fixed portability issues in round_coordinate. Fixes severe graphical glitches in Namco System 22 games on ARM systems (video\poly.h) (ID 09276).
    . Removed most specialisations of the RGB utilities. Added an ARM NEON bilinear filtering implementation. Increased the intermediate precision of the C++ bilinear filtering implementation. Cleaned up and fully inlined the C++ implementation apart from bilinear filtering. Moved the generic C++ implementation to emu\video\rgbutil.h. Put all bilinear filtering implementations out-of-line in emu\video\rgbutil.cpp.
  . MEMORY SYSTEM
    . Fixed debugger's memdump command. Changed memdump to properly report overlapping views (emu\emumem.cpp, emu\emumem_hedr.ipp, emu\emumem_hedw.ipp).
  . INPUT
    . Removed the "optional" field flag (emu\ioport.h). There are multiple issues with this flag: It's poorly defined. Is it an input that's software-accessible but not used? Is it an input that shows in test modes but doesn't do anything useful? Is it an input that the system can be configured to not use? Is it an input that is useful but not strictly necessary? In almost a decade, it hasn't been used widely. It was used in less than ten places. There hasn't been substantial interest in actually applying it across the codebase. It would be an absolute nightmare to try and apply to mahjong and hanafuda games. Consider all the cases where a game may use some but not all of the double-up game controls, and some games support multiple control schemes that use different subsets of the standard mahjong matrix. Trying to apply it to gambling systems would also be a minefield. If we were to expect it to be applied, it would cause an eplosion in input port definitions for platforms with multiple games, adding further maintenance burden. It would greatly reduce the value of having things like the standard mahjong panel definitions as you'd rarely actually be able to use them as-is.
    . Removed PORT_ROTATED from the core. This automatic joystick remapping feature has not been enabled in any driver for years (emu\inputdev.cpp, emu\ioport.cpp and mame/luaengine_input.cpp).
  . LUA engine: Allow configuring analog input adjustments from scripts. Export minvalue and maxvalue for IPT_ADJUSTER (mame\luaengine_input.cpp).
  . 3RDPARTY: Sync AsmJit with upstream version 1.20 from https://github.com/asmjit/asmjit/commit/5134d396bd00c1b63259387acdbb12dfdf009f9b (3rdparty\asmjit).
  . Prevent automatic attempts at loading or creating loose image files with the same names as extant software list items when they fail to load as such. Only allow command line image creation when file is not found and save startup image name for error reporting before trashing it (emu\image.cpp).
  . Updated Chinese (Simplified) translations. The revision refers to the Windows 11 Chinese Simplified menu buttons and option titles, many places are still not perfect, modify it again and again! (Chinese_Simplified\strings.po).
  . Doc: Fixed a typo in the documentation for the default values for the 'comm_localport' and 'comm_remoteport' flags: 15122 -> 15112 (docs\source\commandline\commandline-all.rst).
- Debugger
  . Fixed parsing of unary ! operator in debug expressions (debug\express.cpp)
  . Added support for generating PDB symbols with MinGW Clang and LLD. Also don't disable sibling/tail call optimisation when symbols are enabled. This is hurting our release builds since they're built with symbols. Note: Set PDB_SYMBOLS to 1 to generate CodeView format symbols in separate PDB files, allowing source-level debugging using Microsoft Visual Studio or WinDbg. It can also be used with other tools that can load symbols from PDB files, e.g. the Intel VTune and AMD µProf performance analysis tools. This option is only supported for MinGW builds using the clang compiler and the LLVM linker (lld). This option only takes effect if the **SYMBOLS** option is set to a non-zero value (makefile, scripts\genie.lua, src\main.lua and scripts\toolchain.lua).
  . Fill q.value was not working (debug\debugcmd.cpp)
