  . RC Filter: Renamed the filter types to be more consistent with regards to behavior: old LOWPASS_2C is now LOWPASS (to match the behavior of HIGHPASS); old LOWPASS is now LOWPASS_3R.
  . Yamaha SWP30 sound chip: Start implementing something remotely looking like envelopes (sound\swp30.cpp)
- DEVICE
  . 3dfx Voodoo Graphics: Major Voodoo rewrite: Changed to use modern poly.h instead of polylgcy.h. Moved helper classes into separate voodoo namespace. Derived device classes from video_device_interface. Split classes so that later versions derive from earlier versions. Created device maps to be directly included. Redesigned register mapping to use helper classes and delegates. Rewrote rasterizers to use C++ templates instead of macros. Added logic to compute equations for color/texture combine units. Added special generic identity-texel rasterizer cases. Removed pipeline stalls on texture and palette changes. Removed pipeline stalls on most all parameter changes. Generally re-thought and cleaned up logic throughout. Parameterized cycle stealing on status reads; updated all existing voodoo consumers to configure it as it was before. Restore some cycle stealing on vretrace to allow San Francisco Rush to boot. Increased vretrace cycles to 2 so mace will boot again. Added missing rasterizers for later gtfore games. Removed outdated comments. Improved LOD calculation accuracy. Removed stw_helper as any benefit it provides is within the noise. Improved pixel pipeline throughput for LFB writes. Helps gtfore and related games. Improved fidelity of synchronization points. Added synchronization back to NOP to fix flicker in gtfore06. Fixed dither subtraction. Fixes squares around balls in Virtual Pool. Return 0 on invalid reads (video\voodoo.cpp), seems to fix Funky Ball. Improved logging of unexpected accesses to include register name.
  . Cassette tape image: Don't construct string from nullptr. Note that std::string() was tried but somehow caused another bug (tape preset as play was instead stopped) (formats\cassimg.cpp).
  . K001604 2D tilemaps + 2x ROZ: Added callback for vblank irq (video\k001604.cpp)
  . Namco C355 (Sprites)
    . Fixed handling of sprite attribute table index and sprite position (video\namco_c355spr.cpp), fixes missing sprites in Final Lap R.
    . Adjusted sprite attribute table index mask to accommodate 'J-League Soccer V-Shoot'
    . Use namco_c355spr_device built in sprite buffering to pevent flickering gfx in Suzuka 8 Hours 2
    . Treat 'dy' as signed, seems a more logical solution to Final Lap R 'missing objects' and also fixes the flags on course select screen.
  . PCI: Added support for adding subdevice maps directly (machine\pci.h)
  . Polygon rendering: Various improvements: Exposed poly_array class for broader use. Changed poly_array to intelligently determine maximum size. Added logic to track multiple "last" instances in poly_array. Extended logic to support up to 16m work items. Removed MaxPolys parameter from poly_manager template. Added Flags parameter to poly_manager template. Added POLY_FLAG_NO_CLIPPING flag to remove clipping code when not needed. poly_manager now supports a MaxParams value of 0. Made paramcount a template parameter for render_* functions. Added reset_after_wait() method to be overridden by derived classes. Switched to using std:: helpers instead of internal methods. Removed useless dependency on screen_device. TRACK_POLY_WAITS now produces more complete statistics. Removed legacy implementation of polygon renderer (video\polylgcy.cpp). 'Early out of waits' if no outstanding work (video\poly.h).
  . K001005 Polygon Renderer: Major rewrite and documentation update (video\k001005.cpp): Implemented missing texture+gouraud polygon type. Implemented fog using correct parameters. Fixed lighting calculations. Implemented bilinear filtering in games that use it (Solar Assault and Operation Thunder Hurricane). Use templates for rasterizer code paths. Refactored polygon parser. Disable fog when using constant Z.
  . K056230 LANC: Clear network interrupt properly (machine\k056230.cpp), fixes screen flashing in ZR107 driver.
  . SMC91C9x Ethernet Controller: Reset should disable promiscuous mode. RCR - handle promiscuous changes, adjust soft reset handling. EPH_STATUS should be LINK_OK by default (previous code wouldn't set LINK_OK unless RX_EN is set but LANceGS won't set RX_EN unless LINK_OK is set). B0_BANK bits 4-8 are unspecified in the documentation but LANceGS expects a 3 (used in Card detection logic). MIR values depend on device type and resets when the mmu resets. Reading/writing the data register needs to be aware of 8-bit I/O. Calculate FCS. Removed WMS OUI filtering hack [ksherlock].
- aristmk5.cpp: Updated comments and added some ROM labels
- cedar_magnet.cpp, play_3.cpp and zpinball.cpp: Added working ADPCM sound to EFO ZSU (audio\efo_zsu.cpp) and Magnet System sound boards

- dgpix.cpp: Added list of undumped games
- expro02.cpp: Verified a BTANB: Fantasia and New Fantasia have a service mode but it doesn't work well (text is missing or replaced by garbage). This has been verified to happen with New Fantasia (1994 copyright) on a Comad 940630 PCB.
- gaelco.cpp and wrally.cpp: Eliminated space.device() accesses in machine\gaelcrpt.cpp
- gticlub.cpp and zr107.cpp

  . Adjusted sprite attribute table index mask to accommodate 'J-League Soccer V-Shoot' (video\namco_c355spr.cpp)
  . Added Namco posirq kludge for Nebulas Ray to prevent a bad line on the right of the screen and some stars don't scroll correctly (ID 06666).
- namcos2.cpp
  . Use extra bit on x coordinate (video\namcos2_sprite.cpp), prevents large oversized bad sprites in Final Lap 2/3 and Suzuka 8 Hours.
  . Added Namco posirq kludges for Burning Force to prevent a bad line on horizon (ID 05261) (ID 06944) and for Suzuka 8 Hours 2 tunnels (see 2nd attract demo).
- nss.cpp, sfcbox.cpp and snesb.cpp: Use int8_t instead of old MAKE_INT_8 macro (MAKE_INT_8 fails on GCC/ARM) (cpu\spc700\spc700.cpp)
- royalmah.cpp: Preliminary banking for chalgirl, mjsenka, mjyarou and clone mjyarou2. Girls now appear. These games don't appear to set the palette bank, so they all have bad colors.
- seattle.cpp: Prevent lockups by disallowing 0-duration timers (machine\gt64xxx.cpp)
- turbo.cpp: Added subclasses, input/output finders and save state preparation.
- viper.cpp: Dumped DS2430 and M48T58 for Mocap Golf and Silent Scope Fortune Hunter

- Disco Boy: Fixed tile banking (boss stages) in clone Disco Boy (Promat license?).
- Final Lap R
  . Fixed handling of sprite attribute table index and sprite position (video\namco_c355spr.cpp), fixes missing sprites in Final Lap R (Objects in the side of the track are not shown (ID 05358), AI cars are never reflected in the rear mirrors (ID 05978) and corrupt graphics (ID 06904)).
  . Treat 'dy' as signed (video\namco_c355spr.cpp), seems a more logical solution to finalapr 'missing objects' and also fixes the flags on course select screen.
- Funky Ball
  . Implemented timer. Found a reference to 32539 in the code that looks to be a reasonable guess at the timer frequency. Return 0 on invalid reads (video\voodoo.cpp), seems to fix Funky Ball. Improved logging of unexpected accesses to include register name.
  . Added KS0164 sound cpu
- Gyruss: Fixed comment image hashes to match latest offering (Gyruss diagnostic rom)
- Heroine's Memory: Some basic work to make it display something. Fixed error in GFX ROM loading. Map TE7751 I/O expander.
- The Irritating Maze: Added newer Universe BIOS versions, this allows the Japanese version to be seen by switching the region and joystick play using a cheat although 2.3 and later also support trackball play. A joystick is still required for setup and to use the in-game menu.
- Joker Master: Dumped PROMs and PLDs for clones Poker Master (ED-1993 set 1) and (ED-1993 set 2)

- Sengoku no Jieitai: Changed game title of 'No Man's Land' to 'Sengoku no Jieitai' (ID 08023). Note: This set appears to be the original Japan set. In Japan the game was called 'Sengoku no Jieitai'. "No Man's Land" was the overseas title. Videos from the Japan PCB match the set in MAME.
- Shooting Zone: Made the timer side show something. Added SMS side. Somewhat playable but needs more work.
- Sky Soldiers: Demoted game with MACHINE_UNEMULATED_PROTECTION flag since MCU actually controls bosses time out behaviour 
- Sonic Blast Man: Named a couple of inputs
- Sonic Blast Man's Janken Battle: Map TE7751 I/O expander and some RAM. Tentatively hooked up most devices. Attract mode runs fine but need hopper emulation before it can be playable.
- Space Harrier: Dumped 315-5163A I8751 MCU

- Renamed (rainwrce) to (rainwarrce) and (roboarma) to (roboarmya)
- MAME
  . VIDEO RENDERING SYSTEM
    . Correctly apply -keepaspect with -unevenstretchx/y. Correctly apply -keepaspect with -unevenstretchx/y. Initialize window at the correct size when -intscalex/y is used. Get correct window size upon maximizing/minimizing with integer scaling (emu\render.cpp).
    . Improved min/max for SSE4.1+ and scale+clamp operations for all (video\rgbsse.cpp).
    . Made palette expansion constexpr and added argbexpand function (video\rgbutil.h).
  . MEMORY SYSTEM
    . Removed endianness template parameter from handler_entry_read, handler_entry_write and closely related classes (emu\emumem.*). This appears to substantially reduce compilation time and binary size without too much impact on critical paths. The only critical-path parts really touched by this are probably handler_entry_read_units::read and handler_entry_write_units::write, which no longer need a branch on descriptor endianness for the downcast. The other instances of where the endianness now needs to be fetched from the address space are practically all in constructors, which probably don't get called too often except in drivers where the memory map is regularly rewritten (e.g. segas16b.cpp); even then the performance impact probably isn't huge.
  . INPUT
    . API cleanups (emu\input.cpp and util\unicode.cpp)
    . Allow controller files to override input sequences for inputs that don't use defaults, and to override the toggle setting for digital inputs (emu\ioport.cpp)
    . Expose configuration level (mostly matters for controller files), improved verbose diagnostic messages, and moved a few things out of the global and preprocessor namespaces (emu\config.cpp).
    . Added documentation for some controller configuration file features (docs\source\advanced\ctrlr_config.rst). The device mapping feature documentation will be merged in at some point.
  . List shortnames of subdevices that have ROMs as part of -listroms header (mame\clifront.cpp)
  . Changed osd_ticks to use QueryPerformanceCounter on Windows since the mingw std::high_resolution_clock is anything but (osd\osdcore.cpp).
  . Multi-Language: Updated Brazilian Portuguese translation
  . Filling out missing hashes for commented ROM_LOADs when known
  . Fixed verbose printf (emu\softlist_dev.cpp)
  . hiscore.dat update (plugins\hiscore\hiscore.dat)
- VGM player: Added 22 new entries (hash\vgmplay.xml)
- Compiling
  . Removed some tag lookups (bfm_ad5.cpp, bfm_sc5.cpp, gamtor.cpp, jpmsys7.cpp, seta2.cpp, machine\mcf5206e.cpp and machine\lpci.cpp)
  . Disable another MSVC warning (C4611) that is known to be noisy (and which showed up with the recent setjmp workaround).
  . Fixed Visual Studio case with displaced object base (internal representation seems to have drifted since it was originally written) (util\delegate.h).
- Debugger
  . Fixed mount and create image dialogs (debugger\debugimgui.cpp)
  . Fixed building mametest (tests\lib\util\options.cpp)

General cleanup: Added helper functions for increment and decrement operations and short direct banking. Rationalize use of temporary variables. Modify only lowest 8 bits of accumulator for XOR A, #imm8. Perform a 16-bit rather than 8-bit write for MOVW @RLx + #disp8, A. Use SSB instead of USB for @RW3 or @RW7 addressing when S flag is set. Fixed numerous flag calculations. Emulated many more opcodes. Added interrupt callback for debugger. Correct disassembly of MOVW io, A. Added "extra" I/O CPU (MB90611A F2MC-16) to Motocross Go! configuration

- DEVICE
  . 3dfx Voodoo Graphics: Address minor coverity complaints
  . CHDMAN: Added a few more hard disk templates (Seagate, Maxtor, Micropolis...)
  . Floppy
    . Fixed segmentation fault saving FM track. Incorrect cell size for FM track results in empty bitstream that ultimately causes data.empty() to seg fault (formats\imd_dsk.cpp).
    . Don't assume string iterators can be indexed (reported by Coverity software) (formats\fsmgr.cpp)
  . SMC91C9x Ethernet Controller: m_loopback_result needs to be a signed into so negative status codes remain negative. FDSE bit was masked out. When full duplex switched internet is active, deferrals and collisions not used. Implemented AUTO_RELEASE.
  . TC0780FPA Polygon Renderer: Fixed texture issues in Operation Tiger (video\tc0780fpa.cpp)
- aleck64.cpp: Fixed handling of 8bpp framebuffer mode. Adjusted how VI scan-out functions. Swapped 'magic matrix' dither pattern axes to match hardware tests (machine\n64.cpp and video\n64.cpp).

  . Dumped Peek A Boo Japan 1.1, matches peekaboo set.
  . Standardized PROM locations for games running on 1A board.
- mermaid.cpp
  . Added missing items to state saving
  . Updated to use measured clock and marked Mermaid and clone as imperfect graphics. Note: Incomplete GFX emulation in Mermaid (see MT07985 and MT08000).
- namcofl.cpp: Fixed network status error, this also fixes the paralyzed flagman in Final Lap R (ID 08042).
- ssfindo.cpp: Preliminary QS1000 hook up. There seems to be a bug in the ARM_VIDC20 device that causes static/bad sounds. Just set the related volume sliders to 0 to hear the QS1000.
- timelimt.cpp: Halve maincpu NMI rate and fixed spriteram out of bounds access (ID 08046). Note: PCB output video confirms that the enemies in Progress move too fast in MAME (https://youtu.be/3MX_qCf_no0).
- 4nin-uchi Mahjong Jantotsu: Updated to use finders and other small cleanups
- AGEMAME: Added missing sound roms for 'James Bond (Maygay) (M1A/B) (set 1)'
- Motocross Go!: Added "extra" I/O CPU (MB90611A F2MC-16) to configuration
- Operation Tiger: Fixed lockup issues and improved tilemap emulation in TaitoPJC driver. Fixed texture issues in Operation Tiger (video\tc0780fpa.cpp).
- Royal King Jang Oh 2: Added banking. Almost playable, but bad colors.
- Description changes of Peek-a-Boo! (Japan, ver. 1.1)
- MAME
  . VIDEO RENDERING SYSTEM
    . Fixed automatic sizing of snapshots/recordings (emu\render.cpp). This fixes bad scaling on snapshots and recording when using -uesx and forced scale factors.
  . INPUT: Slightly cleaned up OSD input modules. Removed support for DirectInput 7 and earlier. It hasn't been tested in years, and it's not relevant on any supported OS. DirectInput is effectively finalised at version 8 and is unlikely to get an API update in the future. Use more string[_view] and fewer C strings and tightened up scope of a few things.
- Compiling
  . Fixed OSD=mac compile (osd\mac\window.cpp and osd\modules\render\drawogl.cpp)
- Debugger: Allow the bpset/wpset/rpset & map commands to act on any cpu, by prefixing the index or name with a # and passing as the first parameter (debug\debugcmd.cpp).

A)
- New drivers: radikaldarts.cpp
- New devices: f2mc16, mb90610a, mb90611a and mb90641a
- CPU
  . Fujitsu Micro F2MC-16: Emulated various additional instructions and modes. Fixed banking for direct addressing mode. Fixed semantics of CLRB and number of bytes consumed by SETB. Fixed mistake with calculating N and Z flags for SUB and CMP and writing incorrect result for SUB. Use INC(W)(L) A and DEC(W)(L) A pseudo-operations in disassembly. General cleanup: Added helper functions for increment and decrement operations and short direct banking. Rationalize use of temporary variables. Modify only lowest 8 bits of accumulator for XOR A, #imm8. Perform a 16-bit rather than 8-bit write for MOVW @RLx + #disp8, A. Use SSB instead of USB for @RW3 or @RW7 addressing when S flag is set. Fixed numerous flag calculations. Emulated many more opcodes. Added interrupt callback for debugger. Correct disassembly of MOVW io, A. Added "extra" I/O CPU (MB90611A F2MC-16) to Motocross Go! configuration

- DEVICE
  . 3dfx Voodoo Graphics: Address minor coverity complaints
  . CHDMAN: Added a few more hard disk templates (Seagate, Maxtor, Micropolis...)
  . Floppy
    . Fixed segmentation fault saving FM track. Incorrect cell size for FM track results in empty bitstream that ultimately causes data.empty() to seg fault (formats\imd_dsk.cpp).
    . Don't assume string iterators can be indexed (reported by Coverity software) (formats\fsmgr.cpp)
  . SMC91C9x Ethernet Controller: m_loopback_result needs to be a signed into so negative status codes remain negative. FDSE bit was masked out. When full duplex switched internet is active, deferrals and collisions not used. Implemented AUTO_RELEASE.
  . TC0780FPA Polygon Renderer: Fixed texture issues in Operation Tiger (video\tc0780fpa.cpp)
- aleck64.cpp
  . Fixed handling of 8bpp framebuffer mode. Adjusted how VI scan-out functions. Swapped 'magic matrix' dither pattern axes to match hardware tests (machine\n64.cpp and video\n64.cpp).

  . Made use of object finders and other minor cleanups
  . Documented 'Test' dipswitch for Wully Bully
- clshroad.cpp
  . Added tilemap color bank, fixes lightning flashing and color cycling for Fire Battle.
  . Hand-tuned all clock frequencies for clshroad and halved vblank irq rate, syncing video and sound timings in logical sense. Minor realign documentation.
- megasys1.cpp
  . Documented different clone 'P-47 - The Freedom Fighter (Japan)' ROM board configurations
  . Correction to the audio CPU memory map and verified that clone 'E.D.F. : Earth Defense Force (bootleg)' has an undumped PIC. Verified XTAL and clock.
  . Dumped Peek A Boo Japan 1.1, matches parent set.
  . Standardized PROM locations for games running on 1A board.
- mermaid.cpp
  . Added missing items to state saving
  . Updated to use measured clock and marked Mermaid and clone as imperfect graphics. Note: Incomplete GFX emulation in Mermaid (see MT07985 and MT08000).
- namcofl.cpp: Fixed network status error, this also fixes the paralyzed flagman in Final Lap R (ID 08042).
- naomi.cpp: Documentation misc additions. Corrected PIN number for mask ROMs on 171-8132B carts. Sorted games by year/number.
- ssfindo.cpp
  . Preliminary QS1000 hook up. There seems to be a bug in the ARM_VIDC20 device that causes static/bad sounds. Just set the related volume sliders to 0 to hear the QS1000.
  . Hooked up DIPs for Pang Pang Car. Note: Pang Pang Car uses the VIDC internal DAC for SFX and the QS1000 for music. It's configured to use the undumped internal ROM.
- timelimt.cpp: Halve maincpu NMI rate and fixed spriteram out of bounds access (ID 08046). Note: PCB output video confirms that the enemies in Progress move too fast in MAME (https://youtu.be/3MX_qCf_no0).
- 18 Wheeler: Dumped earlier/prototype Sega 837-13844 JVS I/O board rom epr-21868p.ic7
- AGEMAME: Added missing sound roms for 'James Bond (Maygay) (M1A/B) (set 1)'
- Games Family: Improved notes
- Motocross Go!: Added "extra" I/O CPU (MB90611A F2MC-16) to configuration
- Mushihime-Sama Futari Black Label: Replaced clone 'Mushihime-Sama Futari Black Label (2007/12/11 BLACK LABEL VER)' program ROM with clean dump, previous was dumped from upgraded futari15 PCB and contained trailing garbage.

- Renamed (ainferno) to (ainfernou)
- MAME
  . VIDEO RENDERING SYSTEM
    . Fixed automatic sizing of snapshots/recordings (emu\render.cpp). This fixes bad scaling on snapshots and recording when using -uesx and forced scale factors.
  . INPUT: Slightly cleaned up OSD input modules. Removed support for DirectInput 7 and earlier. It hasn't been tested in years, and it's not relevant on any supported OS. DirectInput is effectively finalised at version 8 and is unlikely to get an API update in the future. Use more string[_view] and fewer C strings and tightened up scope of a few things.
  . 3rdparty
    . Updated BGFX, BX and BIMG to latest. Enable BGFX_CONFIG_DEBUG to get proper asserts.
- Compiling
  . Fixed OSD=mac compile (osd\mac\window.cpp and osd\modules\render\drawogl.cpp)
- Debugger
  . Allow the bpset/wpset/rpset & map commands to act on any cpu, by prefixing the index or name with a # and passing as the first parameter (debug\debugcmd.cpp).
  . Updated debugimgui to compile with latest imgui

Added "extra" I/O CPU (MB90611A F2MC-16) to Motocross Go! configuration
  . I386, MIPS and PPC: Removed a crash caused by the modulus operator (emu\divtlb.cpp). In the original code all values are signed integers, so m_dynindex would overflow and become negative, then the modulus of a negative value by a positive one would generate a negative result and finally the next array read would make the program crash. Also the maximum value plus one of m_dynindex is not generally a multiple of m_dynamic and this would cause a jump in the values of liveindex.

  . 3rdparty
    . Updated BGFX, BX and BIMG to latest.
    . BGFX fixes for various backends. Fixed palette and UYVY conversion in all backends. Fixes rendering for Laserdisc games is flawed (ID 07760). Fixed a typo in render\bgfx\targetmanager.cpp, thanks LN for the heads-up.
    . Applied srcclean to JSON files in BGFX subtree
- ANDROID: Use log write calls directy on Android (osd\osdcore.cpp)
- Compiling

  . MSVC fixes to drivers\royalmah.cpp and stv.cpp
  . Fixed SDL UI choosing the root path (util\zippath.cpp)
  . Use std::clamp in more source files. Use C++17 library function for clamp (and std::min in one place where the value could not possibly be lower than 0 anyway) (video\3dom2_te.cpp).
- Debugger
  . Allow the bpset/wpset/rpset & map commands to act on any cpu, by prefixing the index or name with a # and passing as the first parameter (debug\debugcmd.cpp).
  . Updated debugimgui to compile with latest imgui
  . Debugger-related feature removals and cleanup: Removed the hotspot read tracker. This was never robustly implemented, but changes to the memory system made it much less useful, and the "speedup opportunities" which it aimed to determine are not very important from a current emulation standpoint. Removed the CURSP/GENSP state symbol and the generic sp() getter. Stacking semantics vary too much between CPU architectures for this to be of much use. (A "SP" symbol has been added to a few CPU cores whose stack pointers were otherwise not being registered.). Removed the cached pointer to device_state_interface and the state() fast accessor from device_t. Most users of device_state_interface either already had a pointer to the specific CPU device type or needed to check first for the presence of the interface. Changed the PC memory write tracker to use pcbase(), which works even when the instruction callback is masked out, instead of peeking at the PC history index. Removed some obsolete watchpoint-related definitions from machine.h.
  . Substitute strongly typed enum for magic numbers specifying data format (debug\dvmemory.cpp). Fixed exception in debug memory viewer selecting a floating point format when the number of chunks per row is too small (debug\dvmemory.cpp).



"Theory is when you know everthing but nothing works. Practice is when everything works but no one knows why.
In our lab, theory and practice are combined: Nothing works and no one knows why."
