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

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].

  . 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)

  . 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.

Added internal artwork for Krazy Keno and Jungle King 2004. Promoted Haunted House (IGS, V101US), Haunted House (IGS, V107US) and Haunted House (IGS, V109US) and Jungle King 2004 (V101US) to working.
  . Fixed ADPCM ROM banking for Haunted House and Krazy Keno. Got rid of some stuff carried over from igs_m027.cpp that no games on this platform seem to use (igs\igs_m027xa.cpp).
- igs017.cpp, igs_m027.cpp, igs_m027_033vid.cpp, igs_m027_link.cpp and igs_m027xa.cpp: Boost OKI MSM6295 ADPCM sound volume from half to full
- itech8.cpp
  . Let's mark 'Golden Par Golf' as MACHINE_NOT_WORKING due to lockups in attract mode
  . Removed DEFAULT_RANDOM NVRAM from gpgolf and capbowl. Changed capbowl NVRAM init from all_0 to all_1 (though bowlrama expects all_0).

- model2.cpp
  . Only trigger interrupts if the input changes to the asserted state (i960\i960.cpp). Drop interrupts on reset (i960 IRQ)
  . Correct TGP math lookup table logic, fixes wrong in-game physics in Virtua Cop 2 (ID 09265). Also removed wait state when writing to copro FIFO, no longer needed.
  . Use separate memory spaces for data A and external. Fixes enemy car collision detection in stcc. Added EBU to address for extended A bus accesses (mb86235\mb86235.cpp).
  . 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.
  . 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).
  . Added Virtua Racing layout (layout\vr.lay) also to 'Sega Touring Car Championship', when the cabinet option in the Test Menu is set to Deluxe, the screen's aspect ratio is set to 16:9.
- moo.cpp: Separated original hardware and bootlegs in separate state classes. Modernized sound CPU ROM banking and made region size match ROM size. Reduced run-time tag lookups and literal tags. Cleaned up code.

- nmkmedal.cpp: Correct title for pllovegene and added reference video
- 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).

Cleaned up bitmap drawing functions. Suppress side effects for debugger reads. Reduced run-time tag lookups, literal tags and duplication.
- stella8085.cpp: Clean up driver (adp\stella8085.cpp, machine\i8256.cpp/h and layout\disc2000.lay)
- stv.cpp: Register variables to save states (sega\stvcd.cpp)
- y2.cpp: Added motherboard ROM for System Board Y2

IRQ problem or protection? Some suspect reads with checks.DIPs ports are correct but they don't affect the game / never change in the DIP test screen. Fully recover password (checked from 0x1ce6 on. It starts with 19490817 but where are last two digits checked?).
- Fast Draw (poker conversion kit): Fixed Fatal error: wrong-sized NVRAM region (ID 09280)
- Future Flash/Laser Base: Correct clocks (music pitch and speed)
- Geki Makaimura: Dumped CF card 
- Gradius III: Implemented device_post_load for post-load tasks. Fixed sound routing and cleaned up code. PCB has mono output and only one YM2151 channel is connected (fixes background music balance). Use logmacro.h helpers for optional logging and use BIT helper.
- Hang-On: Dumped PLS153 on sound and ROM board
- Kick and Run: Dumped and verified PALs for clone Mexico 86 (bootleg of Kick and Run, set 1)
- Klax: Documented ROM build date shown in the test menu
- Knights of Valour 3 HD: Added SOC38 internal ROMs
- Konami: Cleaned up code in various Konami devices and systems. Use explicitly sized integers for things that need to be registered for save states. Use references rather than pointers for output parameters of callbacks. Use standard or abbreviated integer types consistently.

- Many Block: Don't apply Macross tilemap offsets to Many Block
- Peek-a-Boo!: Dumped the MCU for Peek-a-Boo!. Note: MCU is not hooked up (it's connected differently to other games).
- Pirate Ship: Removed commented code from machine configuration (K053246 is paired with K053247 or K055673, so m_k053246 is redundant).
- Savage Quest: Convert to new PCI. Stub HASP dongle in a device (centronics\hasp_savquest.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)
