- xtom3d.cpp: Added CAT702 roms to 'Pump it Up' games, CD images will be added soon. Test mode seems to lock up in the 2002 & 2003 games, if you build with Clang 18.1.18 on windows. GCC 14.2.0 on Windows & Clang 16 on MacOS/M1 works.
- '88 Games: Use memory views rather than trampolines (simplifies memory banking). Also improved names of some member functions and changed single-line comments to C++ line comments.
- Acrobatic Dog-Fight: Determine screen refresh rate from PCB video. Small cleanup. Added dipswitch locations, no need for logmacro for warning messages.
- Battle Rangers: Combined input ports
- Bomber Man World (Japan) and Undercover Cops: Changed encrypted opcode 0x37 to map to 0x98 (cvtbw) in dynablaster table (bbmanwj, uccops). Title screen sine wave effect loads a byte from a lookup table and scales it. Byte value needs to be sign extended using 'cvtbw', previous encryption table was mapping 0x37 to 'xch aw, cw'.

- Finalizer: Correct green color PROM decode. Fixes white colour appear purple (ID 03108).
- Gals Panic 3: Added RLE blitter dstaddress (fixes gals gfx issues on 100% clear) (kaneko\kaneko_grap2.cpp)
- Heavy Unit: Confirmed tiles ROM dump for clone Heavy Unit (Japan, alternate ROM format). Note: For the B73 23 ROM: Two 27C2001 EPROMs were piggybacked and soldered together with a flying wire tied from the socket pin 31 (A18) to the bottom EPROM pin 24 (/OE) and a 7404 inverter input. The bottom EPROM chip was selected when A18=0 and the top EPROM chip was selected when A18=1. However, it's been verified the actual data matches the other sets.
- The House of the Dead: Redumped texture ROM for clone The House of the Dead (prototype)

- Dipswitch fixes in docastle.cpp, dogfgt.cpp, dynax.cpp, dynduke.cpp, homerun.cpp, igs_fear.cpp, megadriv_acbl.cpp, namcos12.cpp, namcos23.cpp, quickpick5.cpp and system1.cpp
- Renamed (sectrzona) to (sectrzon), (sectrzon) to (sectrzona), (yamato) to (yamatou) and (yamato2) to (yamatoa)
- MAME
  . VIDEO RENDERING SYSTEM: Fixed apparent bug in draw_quad_palette16_add (emu\rendersw.hxx)
  . DEVICES
    . Don't eat negative cycles with abort_timeslice when icount<0 (emu\diexec.cpp)
    . Added retry_access with abort_timeslice for redoing the access at the same point in time + documentation (emu\devcpu.cpp) (cinematronics\leland_a.cpp, misc\quizpun2.cp and universal\docastle_m.cpp)
  . LUA engine: Exposing full build version to LUA as emu.app_build (mame\luaengine.cpp)
  . INPUT: Guard against automatic integer promotion on arithmetic (emu\input.cpp)
  . UI
    . Fixed sorting. Clones should match parent on list name and short name, instance name of first part is irrelevant. List names actually need to be compared (ui\selsoft.cpp) (ID 08966).
    . Fixed palette viewer if indirect pen exists (ui\viewgfx.cpp)
    . Only check for hold/drag conversion on losing pointer if it hasn't already happened (sdl\window.cpp and windows\window.cpp)
  . CHDMAN: Added a sink for osd_printf_ family function output (tools\chdman.cpp)
  . Mark one path as EXPECTED (emu\schedule.cpp)
  . Don't increment coin counter at power-on when initial counter_w input is 1. Added handlers for resetting counters (emu\bookkeeping.cpp).
  . Consolidated drivers into single files (cclimber.cpp, coolpool.cpp, docastle.cpp, galivan.cpp and vigilant.cpp)
  . Multi-Language: Ukrianian translation updated to actual 0.270. There were minor cosmetic corrections and translating empty problematic strings.
- MAC OS X: Don't use uninitialised NSRect when creating pop-up button. The initial size doesn't really matter because the pop-up button is resized before being added to the container that holds it and the expression field. The disassembly viewer apparently wasn't updated properly like the memory viewer when the auto-sizing code was refactored. Hopefully this will fix the debugger crashing when restoring window positions from configuration (although I would have thought this would cause crashes in more situations if it was the cause of that).
- Compiling
  . Enabled -Wno-tautological-compare for BGFX in order to evaluate turning it off for MAME (src\3rdparty.lua)
  . Fixed several things using memset on non-trivial objects. In particular, this fixes a delegate getting nuked in cpu\powerpc.
  . Cleaned up miscellaneous stuff (namco\vpx3220a.cpp, vigilant.cpp)
  . Use 32x32=64-bit multiply inlines (cpu\drcbec.cpp, cpu\i960, mips\mips3.cpp, cpu\sharc and cpu\v60)
  . Removed assert(0 <= info->clickcnt) (sdl\window.cpp)
  . Fixed build with Clang 19. sol::optional::emplace was broken and depended on the compiler not checking that members exist if the template wasn't instantiated. See ThePHD/sol2#1606 and ThePHD/sol2#1648 (3rdparty\sol2\sol\sol.hpp).
- Debugger: Added callback to allow debugger to break into the middle of wait-type instructions whose execution time is normally indefinite. When this happens, a special message may be printed to the debug console stating the location of the last actual instruction executed before the wait (if there was one). Note that since the callback ignores the current value of the program counter, this special type of debugger break cannot be entered through breakpoints or instruction stepping commands. The callback also leaves no effect on PC history tracking or trace logs (emu\diexec.h and debug\debugcpu.cpp).

- CPU
  . DEC T11: VM1 does not use RMW bus transaction for MOV and MOVB insns (fixes writing to floppy) (cpu\t11\t11ops.hxx)
  . Hitachi H8: Disable logging by default & don't log debugger reads. Only start sending data via DMA if transmitter is enabled. Clear TEND when sending data via DMA. TDRE, RDRF, ORER, PER and FER flags can be cleared to 0 only if they have first been read while set to 1. Only set TEND when there is no more data to send. Receiver is started only on high to low rxd in asynchronous mode, when receiving and sending in synchronous mode when data is sent, or continuously when receiving without sending in synchronous mode. Set rx status to idle when stopping clock in rx_async_step(). Removed double invert when calculating parity in rx_async_step(). Removed redundant check for synchronous mode in rx_async_step() (h8\h8_sci.cpp).
  . Hitachi HD44801: Set page start to 0x3f (hmcs40\hmcs40d.cpp)
  . IBM PowerPC: Fixed QNan check. a) All constants were one digit too short. b) The payload was always expected to be 0 (which is just a special case qnan (Real Indefinite) though) (powerpc\ppccom.cpp).
  . Intel 4004: Don't log messages about NOP aliases for the 4004 (the Linux/4004 firmware uses these for instrumentation points) (mcs40\mcs40.cpp)
  . Motorola MC68000: Renamed m_instruction_restart to m_can_instruction_restart to clearly distinguish from m_restart_instruction
  . Motorola MC68000 FPU: Added FPU instructions 'FETOX', 'FETOXM1', 'FTWOTOX' and 'FTENTOX' (m68000\m68kfpu.cpp, softfloat3\bochs_ext\f2xm1.c, softfloat3\bochs_ext\softfloat3_ext.h)
  . Motorola MC68030: Added gdbstub support

    . Removed #include "screen.h" (imagedev\floppy.h)
    . Don't enable_transfer after tc. Indicate ready status in polling irq sense. Reset st0 when starting a seek and fail if drive isn't ready (machine\upd765.cpp).
    . Added read 86f image support (formats\86f_dsk.cpp). Different workaround for (unused) BIG_ENDIAN enum (formats\86f_dsk.h).
  . Fujitsu Micro F2MC-16: Created devices for the onboard analogue to digital converter, clock generator, interrupt controller/Extended intelligent I/O service, I/O port, Programmable Pulse Generator, reload timer and UART. CPU core exposes the RMW line for onboard devices. Log messages will contain the address of the start of the instruction, rather than the next byte the CPU is about to fetch. Added INT9/INT addr16 & INT addr24 software interrupt instructions. Fixed INCW @RWx & DECW @RWx instruction length. Added missing fetch of immediate value in MOV @RWx + RW7, #imm8.
  . Intel 82371 southbridge: Reduced PIT range. i82371sb_isa_device can now redirect their IRQs (machine\i82371sb.cpp). 
  . MC68681 DUART/SC28C94 QUART: Unambiguous xr68c681 control blocks. 'SC28C94 QUART' has 64 registers (machine\mc68681.cpp).
  . National Semiconductor NSC810 RAM-I/O-Timer: Save internal state (machine\nsc810.cpp)
  . Real Time Clock interface: Devirtualize set_current_time and cleaning up misuse (emu\dirtc.h)

- igs_m027xa.cpp
  . Dumped internal CPU ROM for clone Crazy Bugs (V103JP). Promoted game to working. Fixed inputs for clone Crazy Bugs (V103JP). Got rid of hopper from Crazy Bugs (V103JP) since there appears to be no way to use it and exposed hopper switch as a user input so it can still be tested. Got rid of third bank of DIP switches from Crazy Bugs (V103JP) as comments indicate it isn't physically present (although it is displayed in the input test).
  . Use mnemonic short names for clones
- igs017.cpp
  . Dumped GFX ROM for clone Tarzan Chuang Tian Guan (China, V110)
  . Fixed DIP switches and cleaned/improved inputs for Chaoji Da Manguan II, Manguan Caishen, Manguan Daheng, Shuang Long Qiang Zhu 2, Tian Jiang Shen Bing and Tarzan Chuang Tian Guan. Correct Long Hu Zhengba 2 DIP switch settings and cleaned up inputs.
  . Reduced repetition in inputs a little, made conventions a bit more consistent across files and correct a few comments.
  . Use slots input types for Tarzan Chuang Tian Guan in "joystick" mode to make playing slightly less confusing. Removed mahjong keyboard row that isn't read from Tarzan Chuang Tian Guan.
  . Added notes about game controls
- lwings.cpp: Hooked up sound CPU reset control for Trojan and Avengers. Original Trojan schematic shows that the main CPU controls the sound CPU reset line.
- megadriv_acbl.cpp
  . Hook up PIC MCU to Bare Knuckle II (bootleg of Mega Drive version). Promoted game to working. TODO: Unknown inputs to Port B of the emulated PIC. MCU clock frequency. There is only a 50 MHz XTAL on the PCB, are the other clocks correct?
  . Sorted DIP switch options. Order coinage options from least to most generous, put off to the left of on.
- midvunit.cpp: Fixed range error in "Galil" wheel controller emulation (midway\midvunit.h)
- mosaic.cpp: Minor cleanups. Suppress side effects for debugger reads. Use more appropriate types for some integer variables. Use generic graphics decoding layouts, made CPU ROM region size match size of ROM.
- multfish.cpp: Minor cleanups: Use more appropriate types for integer variables and made some variables constant. Allocate video RAM on start and reduced run-time tag lookups. Improved some function and variable names and reduced use of static functions and preprocessor macros. Cleaned up spacing and converted single-line comments to C++ line comments.
- multfish_boot.cpp: Converted single-line comments to C++ line comments
- namcos12.cpp and namcos23.cpp: Added a new modular JVS framework. New devices added: Namco Cyber Lead I/O LED(I/O) PCB 8699014200, Namco Cyber Lead I/O LED(I/O) PCB 8699014200 (compatibility patch), Namco Cyber Lead I/O LED(LED) PCB 8699014500, Namco AMC PCB (Extra I/O,JPN,Ver1.10), Namco ASCA-1 (Multipurpose I/O,JPN,Ver2.00), Namco ASCA-3 (Multipurpose + Rotary Encoder,JPN,Ver2.04), Namco ASCA-3 (Multipurpose + Rotary Encoder,JPN,Ver2.02), Namco ASCA-5 (Multipurpose,JPN,Ver2.09), Namco CSZ1 MIU-I/O (GUN-EXTENTION,JPN,Ver2.05), Namco EM I/O1-02 (Techno-Drive I/O,JPN&EXP,Ver2.00), Namco TSS-I/O (GUN-EXTENTION,JPN,Ver2.02) and Namco XMIU1 TSS-I/O (GUN-EXTENTION,JPN,Ver2.11,Ver2.12). Note: The Cyber Lead compatibility patch is required because later versions aren't. Namco FCA-1 (Multipurpose + Rotary Encoder,JPN,Ver1.00), Namco FCA-1 (Multipurpose + Rotary Encoder,JPN,Ver1.01) and Namco FCB (TouchPanel&Multipurpose,JPN,Ver1.02). Note: These use ASCA3 patched to return the correct ID string as the full ROM is yet to be extracted. Namco EM Pri1-01. Note: The printer for Techno Drive is HLE'd only enough to make the game happy.
- namcos12.cpp
  . Promoted Kart Duel (World, KTD2/VER.A) and clone (Japan, KTD1/VER.A) to working (ID 08867)
  . Added Namco C77 CPU (custom H8)
  . Converted Namco System 12 to allow JVS or JAMMA in each game. See src\devices\bus\jvs\cyberlead.cpp for list of games that support Namco Cyber Lead cabinet animations. Moved CDXA documentation and memory map into it's source file, converted the shared memory to 16bit on the PlayStation side and acknowledge the interrupt correctly. Converted to logmacro.h. Setup analogue inputs to match the games defaults, except Kart Duel because the defaults seem impossible to achieve. Made set names and formatting consistent.
  . Added Techno Drive LED artwork. Lower analog controls keydelta for Techno Drive.
- namcos23.cpp
  . Significant improvements. More games boot and are playable, albeit with glitchy graphics at times. Fixes Race On causes MAME to freeze after self-test (ID 08924).
  . Increased timeout in namco_csz1 ROM to stop it timing out, the H8 is either running too fast or the SUB CPU is running too slow (jvs\namcoio.cpp).
  . Configured Crisis Zone gun to match game defaults & default to namco_csz1 JVS I/O board. Stop motor error in Crisis Zone test mode
  . Removed texture_enabled flag, it caused missing graphics so this bit must have a different meaning. Reset poly counts each frame to prevent trailing graphics and MAME crashing when holding INS.
- pgm.cpp: Removed unneeded trampoline (igs\pgm.cpp). Fixed some regressions (igs\pgmprot_igs027a_type1/3.cpp).
- sigmab98.cpp: Fixed regression with hopper motor. Fixes all games using the Sammy Medal BIOS set except tdoboon: Games return "Hopper Overrun" error upon exiting service menu after backup RAM initialization (ID 08941).
- taito_f3.cpp: Added TODO note to use common TC0640FIO device

  . Cleaned up code: Use palette_device handlers for palette. Correct video RAM width and changed to allocate on start. Constrain screen update to clipping rectangle. Fixed input matrix reading. Reduced literal tags, changed logging to use logerror and made come variables const. Reduced duplication and improved ROM region names. Added notes about languages for in-game text and voice samples. Use C++ line comments for single-line comments.
  . Fixed I/O and DIP switch settings. This makes it possible to complete a game with either mahjong keyboard or joystick controls.
- Mirax: Minor cleanups. Use more appropriate types for some variables. Simplified graphics ROM decoding. Reduced literal tags, made some variables const, improved ROM region and variable names.

- Dipswitch fixes in funtech.cpp, gkigt.cpp, igs017.cpp, igs_m027.cpp, igs_m027xa.cpp and megadriv_acbl.cpp
- Renamed (cjddz) to (cjddz215cn), (crzybugsj) to (crzybugs103jp), (crzybugsb) to (crzybugs200us), (crzybugsa) to (crzybugs202us), (fgtlayerj) to (fgtlayerja), (fruitpara) to (fruitpar206us), (haunthiga) to (haunthig101us), (kartduelj) to (kartduelja), (lthy) to (lthyp), (mgzza) to (mgzz100cn), (mrdrillrj) to (mrdrillrja2), (oceanpara) to (oceanpar101us), (olympic5a) to (olympic5107us), (soulclbr) to (soulclbrac), (soulclbra) to (soulclbr), (soulclbrja) to (soulclbrja2), (tektagtc1) to (tektagtc1a), (tektagtja) to (tektagtja3), (tenkomorja) to (tenkomorja1), (tripfevb) to (tripfev105us), (tripfeva) to (tripfev107us) and (unkwht) to (yizhix).
- MAME
  . VIDEO RENDERING SYSTEM: Always translate coordinates if container is found (emu\render.cpp). Fixes Touch drag gestures that leave the window do not behave correctly. The menu jumps to an unexpected position when the touch point is outside the window.
  . MEMORY SYSTEM: Allow ioport finders in portr/w/rw. Converted a number of drivers to use ioport finders in the memory map. This is not entirely gratuitous. The idea is to ensure all the ports are in the class, so that eventually ioport finders become ioport creators. The ultimate aim is to C++-ify port descriptions which would be made way nicer by getting rid of the need for PORT_START (emu\addrmap.h).
  . DEVICE: Improved stop bit handling. Fixes bytes are read too slow in serial emulation. Never check more than one stop bit on reception. Don't add an extra stop bit on transmission. Got rid of the per-instance parity lookup table (emu\diserial.cpp).
  . INPUT
    . Fixed deadlock issue with joystick (removed reset() call during process_event) (input\input_sdl.cpp)
    . Added piano keyboard definitions and automatic names (emu\ioport.cpp)
    . Improved validation of DIP switch locations. Treat an empty switch name as an error. Treat a non-positive switch number as an error. Also allocate fewer temporary strings (emu\ioport.cpp).
    . Made syntax for configuring callbacks more consistent. You now use FUNC or NAME to configure port field callbacks, like you would when configuring other kinds of callbacks. This has a number of benefits: No need to remember different syntax for port field callbacks and more approachable for new contributors. May use function templates with multiple arugments using NAME((&...)) syntax without resorting to another layer of macros. May use non-member functions on the odd chance it's useful. More natural syntax for referring to member functions (emu\ioport.h).
  . UI
    . Allow pressing UI Clear to restore default pointer timeout settings (ui\ui.cpp and ui\videoopt.cpp)
    . Don't ignore character input when no pointer is active (ui\selmenu.cpp). Handle menus resetting items from custom pointer handlers better (ui\menu.cpp).
  . CHD/CHDMAN
    . Made some APIs return errors rather than throwing exceptions (util\chd.cpp and util\chdcodec.cpp)
    . More API changes: Have metadata_find return std::error_condition instead of throwing an exception. Replaced the is_XXX predicates with check_is_XXX methods that return a std::error_condition, enabling improved error reporting for cdrom_image_device. Retain read error information in chd_file_compressor. Make a bunch of methods noexcept (util\chd.cpp).
    . Throw errors when examining metadata to determine compression defaults (tools\chdman.cpp)
    . Made a few more member functions return error conditions. Also mark error paths as unexpected to optimise against them (util\chd.cpp).
    . Added a safer way to let codecs do special stuff with hunks (util\chd.cpp and util\chdcodec.cpp)
  . Improved notes about DirectX SDK and added a link in compiling instructions. Also fixed typo "SDL" in place of "SDK" (docs\source\initialsetup\compilingmame.rst).
  . Consolidated drivers into single files (fuukifg2.cpp, supbtime.cpp)
- Compiling
  . Added ATTR_COLD to common lifecycle methods for many files in src\mame and src\devices
  . Use qmake to query Qt libexec directory to find moc (osd\modules.lua)
  . Upgrade checkout and upload-artifacts actions (github\workflows\*)
- Debugger
  . Clean up #includes a bit (emu\debug and osd\modules\debugger\qt)

    . UI pointer options: Set inc/dec to 1s (hold shift for shorter 0.1s). Allow 0.0s hide delay to disable pointer. Warning message if delay is set to 0.0s.
    . Be consistent with custom_render passed variable names (ui\*)
    . Changed driver status "Overall:" to "Status:" (ui\selmenu.cpp and ui\simpleselgame.cpp)
    . Avoid floating point equality comparison. Fixes pointer input not working on menus at some window sizes in 32-bit x86 builds (ui\menu.cpp).
  . INPUT: Offset analog value by half a step because of rounding issue when crossing 0 (crossing 0 now takes 1 step instead of 2, and there's 0.5 step wiggle room at edges) (emu\ioport.cpp)
  . Consolidated drivers in single files (shangha3.cpp)
- Debugger
  . Don't sleep waiting for events on debugger update (debugger\debugqt.cpp)
  . Added -debugger_host option. This allows setting the host to 0.0.0.0 to accept connections from outside of localhost. Command line options need to be documented. Don't assume C strings returned as option values remain valid indefinitely. Fixed wording for option description (debugger\debuggdbstub.cpp and lib\osdobj_common.cpp).
  . Fixed bad display if view is scrolled horizontally (debug\dvdisasm.cpp)
  . Don't restrict maximum window sizes (debugger\win\debugwininfo.cpp)

- CPU
  . Fujitsu Micro F2MC-16: Flesh out CPU emulation. Support INT #vct8, LSL A, R0 and FILSWI instructions. Support many more EA-type instruction modes. Prevent MOVS(W)I and FILS(W)I from clobbering RW0 if it lies within the destination range (f2mc16\f2mc16.cpp).
  . Hitachi H8: Added system clock getter (divided clock()) (h8\h8.h, h8\h8_sci.cpp and h8\h8_timer8.cpp). Added safety check in internal_update for possible negative ticks (h8\h8_sci.cpp).
  . Intel I386
    . Some limit checks. Note: This a hack, only use if there are sync problems with another cpu (i386\i386.cpp). Disable logging.
    . Correct buggy fxsave and fxrstor opcodes and let Chihiro show 3D again (i386\pentops.hxx)
    . Correct errors in pentops.hxx caused by bad mmxprolog routine. Currently the mmxprolog routine can raise a #NM exception. But the caller will execute the MMX opcode anyway, unfortunately by fetching the bytes from the first instruction in the exception service routine. This adds a bool return value to mmxprolog so the caller can return too without making a mess (i386\pentops.hxx).
    . x87 stack top set to 0 when entering MMX state, generate #NM only from TS bit. MMX opcodes generate #NM only when TS is set, EM bit generates #UD (i386\pentops.hxx).
    . Correct various MMX and SSE opcodes in pentops.hxx. Expecially for the case when the source and destination registers are the same. Moved a couple Cyrix routines together with the other ones (i386\pentops.hxx).
    . Fixed cycles when leaving rep when out of cycles and count == 0 (i386\i386ops.hxx)
  . Motorola MC6809: Added sync acknowledge callback (m6809\base6x09.lst and m6809\m6809.cpp)
  . Motorola MC68000 FPU: Fixed fmovem reads for mode=2. Note: 'Updated 680x0 FPU to Softfloat' in MAME 0.267 changed the write part, but missed to convert the read part. This fixes booting HP-UX 9 on hp9k_3xx (m68000\m68kfpu.cpp).
  . Philips MX10EXA: New Philips XA CPU and disassembler
  . Texas Instruments TMS32020: Added primary TMS32020 support
  . Texas Instruments TMS32025: Allow stack push/pop to be inlined
  . Zilog Z80: Fixed compile issue (z80\z80ndasm.cpp). Small cleanup (z80\z80dasm.cpp). Reset m_ref when PC is changed through state_import (z80\z80.cpp).
- SOUND
  . Acclaim RAX: Use device_mixer_interface for sound route. Cleanups. Use C++ style comments for single line comments. Suppress side effect for debugger reads. Make variables constant. Fixed spacing. Reduced literal tag usages. Added variables into save state (shared\rax.cpp).
  . Beep and DAC: Increased sample rate in favor of better resample quality. Small cleanup. Added note about buffer size (sound\beep.cpp and sound\dac.cpp).
  . Biquad Filter: Added protection against Biquad Filters producing aliased output or other noise if the stream sample rate is below the cutoff of the filter. Converted to use logmacro.h and added some additional optional log messages. Fixed some incorrect calculations for the MFB band-pass filter parameters (sound\flt_biquad.cpp).
  . Yamaha YMF292-F SCSP: Use util::sext for sign extension and use lowercase hexadecimal literals (sound\scspdsp.cpp)
- DEVICE
  . ATA: Clear DMA modes when switching to PIO mode. Do not log reads when reading from the debugger (machine\atahle.cpp).
  . Floppy: Drive busy bits should not be cleared until a SIS is executed (machine\upd765.cpp). Note: The upd765 does not clear the drive busy bits until you issue a sense interrupt status command. Without this fix CP/M Plus on the QX-10 gives disk I/O errors because it expects the busy bit to stay set until it has a chance to issue the SIS command.
  . K056230 LANC: Refactor regs_r/_w to regs_map. Preliminary LANC support for viper.cpp.
  . PC hardware: Connect iochrdy properly. Also don't forward the same thing more than once - it could be std::move'd out the first time (machine\genpc.h).
  . Rockwell 65C52 DACIA: Added Rockwell 65C52 Dual Asynchronous Communication Interface Adapter. A slightly tweaked combination of two 6551 ACIAs on a single chip. Correct bug associated with IRQ handling. Simplified update_irq. Added call to update_irq at each place IER or ISR changes and debugger side effects check on reads (machine\r65c52.cpp).
  . RS-232 Port: Added Mouse Systems serial mouse to default RS-232 devices (rs232\rs232.cpp).
  . Sony LDP-1450: Added HLE of player and hookups to some games that use it. Tweaked timings. Added some more comms and text overlay logging. Added multibyte command support (machine\ldp1450hle.cpp).
- aerofgt.cpp, crshrace.cpp, f1gp.cpp, fromance.cpp, gstriker.cpp, inufuku.cpp, pspikes.cpp, suprslam.cpp, taotaido.cpp and welltris.cpp
  . Implemented device_gfx_interface to decode graphics and use delegates for priority mapping (vsystem\vsystem_spr.cpp).
  . Implemented device_gfx_interface to decode graphics and fixed issues with save states (vsystem\vsystem_spr2.cpp).
  . Merged aerofgt.cpp driver into single file and moved every set but aerofgt itself into a separate driver (pspikes.cpp). Reduced code duplication.
  . Use generic graphics decoding layouts for crshrace.cpp, suprslam.cpp and welltris.cpp.
  . Tidied bootleg sprite drawing code in f1gp.cpp
  . Fixed sprite delay in gstriker.cpp
  . Added comment about possibly incorrect tilemap offset to inufuku.cpp
  . Use generic graphics decoding layouts for welltris.cpp
- alpha68k_i.cpp: Small cleanup to spacing
- bombjack.cpp: Avoid needing to remove and replace devices in machine configuration
- cave.cpp: Use actual resonator value for the OKI6295 on donpachi, jumbogod, paccarn, paceight and pacslot.
- cclimber.cpp: Improved driver. Small cleanup.
- cesclass.cpp: Break LCD output in two screens. Implemented bitmap DMA trigger (fix screen tearing). Replaced palette with amber shades.
- chihiro.cpp
  . Correct buggy fxsave and fxrstor opcodes and let Chihiro show 3D again (i386\pentops.hxx)
  . Correct errors in pentops.hxx caused by bad mmxprolog routine (i386\pentops.hxx). Fixes graphics goes blank in all Chihiro games (ID 08617).
- cops.cpp: Fixed loose input that stopped Nova games from booting. Srcclean and tidy.
- igs_fear.cpp
  . New Philips XA CPU and disassembler. This adds basic execution to XA core. It emulates enough of the XA to give fearless and superkds working sound. Only the exact forms of the opcodes used so far have been implemented. No optimizations have been done, use of const, inline use, templates etc. are planned for a future update; code is still primed for debugging and development. Overall structure, code style are not 100% final (see above) and will be adjusted as the CPU is better understood. Peripherals, interrupts etc. are not yet fully implemented, nor is anything outside of the page zero mode used here due to lack of test cases.
  . Hooked up Philips MX10EXA CPU to fearless and superkds. Fixed fearless decryption. Added IGS027A dump.
  . Added timer and interrupt, RTC, input and dipswitch and fipx in sprite drawing. Promoted Fearless Pinocchio and Super Kids to working.
- igs_fear.cpp, igs_m027.cpp and pgm.cpp: Fixed endianness issue for 32-bit games (igs\pgmcrypt.cpp)
- igs_m027.cpp: Hooked up Philips MX10EXA CPU to crzybugs and haunthig
- macrossp.cpp: Cleaned up code. Marked quizmoon as having imperfect graphics and sound due to incorrect blending and sound in title scene. Use object finder arrays and function templates for tilemaps and related stuff. Use generic graphics decoding layouts. Reduced literal tag usage and improved ROM region names.
- merit.cpp
  . Implemented proper use of bit 0 in m_extra_video_bank_bit. Promoted Match'em Up (6221-51, U5-1) and clones Match'em Up (6221-55, U5-1 German), The Couples (set 1), The Couples (set 2) and The Couples (set 3) to working.
  . Made the video control bits a bit clearer
  . Added preconfigured NVRAM to avoid error on boot. Fixed 'Points Per Coin' dipswitch. Promoted Montana Super Draw (4436-05, U5-0) to working.
- model1/2.cpp: Measured clocks (shared\segam1audio.cpp)
- model1/2/3.cpp: Fixed volume. Added variables into save states. Cleanups. Moved devices into private. Initialize variables at machine start. Removed hardcoded tags and literal tag usage. Added notes. Fixed spacing. Constantize values. Use correct typename values (sega\dsbz80.cpp).
- namcos10.cpp: Preliminary Namco MEM/IO board support. Added Toshiba TC58256AFT flash device (machine\nandflash.cpp).
- nmk16.cpp
  . Extract NMK004 internal ROM using a new technique. It was dumped from two different devices taken from Acrobat Mission and Thunder Dragon boards. The dump was exactly the same from those 2 devices, so I consider it a good and reliable dump. It was achieved using a custom tool to read internal ROMs from TLCS90 MCUs: https://github.com/sergiopolog/tlcs90-rom-reader. Previously existing dump made by 'trap15' only differs in 3 bytes starting at 0xFBD address. That difference could be caused by the method used to extract the ROM back then. Actually, I talk to him about it and he stated that area around 0xFBF address was marked as unsure when he carried out the process (nmk\nmk004.cpp).
  . Adjusted values for proper screen size, timings and interrupts according to real hardware. Fixed timings and flip-screen for NMK16 games. Removed MACHINE_NO_COCKTAIL flag from airattck, bjtwin, macross2, nouryoku, sabotenb, ssmissin and tdragon2 and clones. Added MACHINE_NO_COCKTAIL flag to tharrier and clones. Fixed background offset for some Afega games. Fixed offset in the additional bg layer of strahl and bioship. Fixed flipscreen on bioship and vandyke.
  . Fixed max sprite clock related to screen size. Upgraded interrupts trigger system based on PROM contents. Added info about screen resolutions and timings. Fixed NMK16 prom timing.
  . Merged powerins.cpp into nmk16.cpp driver to make use the new interrupt system. Fixed interrupts config for clones Power Instinct (USA, bootleg set 2) and Power Instinct (USA, bootleg set 3).
- segaufo.cpp: Assume NMI enable is on IO2 CNT1. Fixed regression with debug popmessage. Small cleanups.
- snesb.cpp: Fill in missing DIP switches for several games. Added continue counter init for Wild Guns (SNES bootleg).
- spoker.cpp: DIP switches are a switch matrix
- viper.cpp
  . Preliminary K056230 LANC support. Applies portions of Hydreigon's basic LAN controller implementation for Konami Viper (PR #12546). Fixes gameplay hangs/crashes in gticlub2, xtrial, code1d and wcombat.
  . Hookup World Combat inputs. Updated QA.
  . Removed all clones with alt CF dumps of the same version: p911ea, thrild2ab, thrild2ac, tsurugie and wcombatb. Marked clone Thrill Drive 2 (ver EAA) CF dump as bad (blue screens because of it).
- zn.cpp: Cleanups. Suppress side effects for debugger reads. Make variables constant.
- 64th. Street: Use default 'Lives' setting from manual
- Buggy Challenge: Improved sky gradient blending. Hookup unused DSW1:8.
- Cherry Master '91: Redumped GFX rom. Fixes spurious white dots on some reels.
- Cosmo Gang: Small cleanups
- Daytona USA: Dumped audiocpu roms for clone Daytona USA
- Dodge City: Promoted clones Dodge City (2131-82, U5-0D), Dodge City (2131-82, U5-50) and Dodge City (2131-82, U5-0 GT) to working
- FreeWay: Added very preliminary drawing and palette decoding
- Gaelco Football: Added notes and rom placeholder
- Megatouch 5: Added NVRAM to clone Megatouch 5 (9255-60-01 R0C, Standard version). Promoted game to working. Note: Game will NOT start without a valid NVRAM.
- Midnight Landing: Use TMS32020 DSP instead of TMS32025
- Monza GP: Dumped a Monza GP original PCB which had the same roms as clone Monza GP (bootleg). Dropped the bootleg designation from the title.
- Multi-Action 6710-21: Hacked a bit to make game show something. It starts with game malfunction message. It can be started by switching IN2:2 on, then pressing discard 3.
- Odyssey: Added NCR53C825_PCI stub
- Revelations: Added CHD. Create an HLE implementation of the Sony LDP-1450 laserdisc player. Added Rockwell 65C52 Dual Asynchronous Communication Interface Adapter. Promoted game to working.
- Seibu Cup Soccer: DIP Switches updates for clone Goal! '92
- Street Smart: Added PLDs to clones streetsm1, streetsmj and streetsmw.
- Super Poker (v306US): Promoted Super Poker (v306US) and clones Super Poker (v102UA), Super Poker (v200UA), Super Poker (v201UA), Super Poker (v203US) and Super Poker (v205US) to working.
- Superstar (4435-81, U5-1): Promoted game to working
- Terra Cresta: Fixed the filters and mixing resistors on clone Terra Cresta (YM2203)'s YM2203 SSG channels A+B-tied-together and C being inadvertently swapped. Fixes BGM bass is not playing (ID 08886). Added a note that this circuit needs to be converted to a netlist to be accurate due to the unusual hookup, and added a boost factor to the SSG channels to temporarily work around that fact.
- Tetris: Redumped OKI ROMs for clone Tetris (bootleg set 7, with OKI M5205)
- Zing Zing Zip: Made clone Zing Zing Zip (bootleg) go a bit further, marked its Oki ROM as bad. Main blocker is the different sprite format.
- Fixed rom names in expro02.cpp, missile.cpp, namcos2.cpp, merit3xx.cpp, naomi.cpp and toaplan1.cpp

- MAME
  . VIDEO RENDERING SYSTEM
    . Generate cosine table at compile time. Made cosine table constexpr, got rid of lambda and loop. Appease complilers that don't believe in constexpr trigonometry. Don't use class template deduction with large initialiser list that upsets Clang (emu\rendersw.hxx).
    . Added decoder for xxxxxBBBxGGGxRRR format (emu\emupal.cpp)
  . UI
    . Do an extra item reset the next time through the event loop after making a change. Updated DIP switch and configuration field values aren't seen in the port value until the next I/O port manager frame update, and hence enable state won't be seen until then (ui\confswitch.cpp) (ID 08878).
    . Dismiss error messages on pressing left or right (ui\selmenu.cpp)
  . Updated "CPU Tester" sample code so it will mostly build and work again. Only remaining issue is that m_icountptr is now private, so it can't set remaining cycles (emu\drivers\testcpu.cpp).
  . Merged drivers in single files (aerofgt.cpp, prehisle.cpp and snk68.cpp)
- Compiling: Various cleanup
- Debugger: Fixed crash on hard reset (debugger\qt\mainwindow.cpp and windowqt.cpp)
