- New Cheat.dat: http://www.mamecheat.co.uk/index.htm
- DS5002FP protection
  . Added dumped Dallas DS5002FP chips to TH Strikes Back, Touch & Go and World Rally 2 using the method published by Morten Shearman Kirkegaard and Peter Wilhelmsen as documented at http://www.afdelingp.dk/files/articles/ds5002fp/ds5002fp.pdf
  . Touch & Go and World Rally 2 are now playable. A 2nd verification pass is still needed on them from additional boards, as bad bits existed in World Rally 2 even prior to extraction (steering logic was broken but bad byte was identified and fixed as the code for that command handler was identical to World Rally 1) and TH Strikes Back is crashing at the first boss (could also be a CPU core issue). Glass was also dumped, but at the time the data wasn't extracted, only the code, and the board has since died, so needs redoing.
  . Use DS5002FP dumped from 2nd PCB for World Rally 2, it confirms the byte fix made to the previous dump and also highlighted another. Also interestingly the startup code appears to have been patched slightly on the first board, maybe they knew ram was failing on it?
- I4004 CPU
  . Rewrote 4004 core and disassembler: Renamed to MCS-40. Emulated 8-clock instruction cycle, interruptible at any point. Converted TEST input to an input line. Added SYNC and CM output lines. Added support for 4040 CY output, logical operations, extended registers, ROM banking and disassembly. Made I/O space mapping more flexible to support the variety of peripherals available. Notable missing features are 4040 interrupt and halt, and "program memory" space.
  . Make disassembler/debugger use syntax closer to what ASL accepts. Use 2D lookup to make debugger tables more compact. Allow 4-bit registers to be set independently. Save state fixes. Implemented WPM/RPM instructions. Expose some signals from a 4008/4009 or 4289. Can't use opram when program and opcodes are not related in the slightest. Check for disabled side-effects! Better reflection of 4289 timings for performing program read/write.
  . Added support for 4040 stop/ack and HLT instruction, hook up stop/single step buttons in (MESS) INTELLEC 4/MOD 40
  . Splitted ROM and RAM port address spaces. Splitted RAM memory and status address spaces (no more read/modify/write). Fixed bug in FIN handling. Exposed cycle callback.
- M377xx CPU: Preliminary M37720 support
- M6800 CPU
  . Document more CPU types
  . MC6800 LSR/ROR/ASR instructions set overflow flag (V flag) to 'N' XOR 'C' (ID 06624)
- MB88XX CPUs: Converted MB88XX ports to DEVCB and removed generic device type (audio\namco52.cpp, namco54.cpp, drivers\arabian.cpp, strnskil.cpp, machine\namco50.cpp, namco51.cpp, namco53.cpp and namco62.cpp)
- MC68340 CPU: Added config macros and callbacks for 8 bit ports A and B (machine\68340.cpp). Added 8 bit ports A and B, updated LOG system (machine\68340sim.cpp).
- N2A03 CPU: Added auxillary output callback (machine\midwayic.cpp)
- PIC16C74 MCU: Load recent CAPS0ff PIC16C74 MCU dump for croupier and croupiera, not hooked up for now.
- TMP68301 CPU: Interrupt cleanups
- DCS sound
  . Get audio to start working (audio\dcs.cpp) in Skins Game (1.06)
  . Re-enable speedups for external ram
- Namco CUS30, YM2151 and YMF271 sound: Support dynamic changes to clock frequency
- OKI6376 sound: Replaced custom handlers with device_clock_changed
- Sound Interface
  . Soundlatch modernization in starwars.cpp and xain.cpp
  . exprraid.cpp: Use MCFG_GENERIC_LATCH_DATA_PENDING_CB
  . firetrap.cpp: Sound-related modernization. Use callback for soundlatch interrupt. Use modern MSM5205 callback and LS157 selector, and eliminate an instance of HOLD_LINE. Clean up some names. Added placeholder 8751 device.
  . gcpinbal.cpp: Modernized the callback of the MSM6585 sound
  . gladiatr.cpp: Hook up SSRST (sound reset) according to badly scanned schematics
  . magmax.cpp: Soundlatch modernization & various stuff from schematic
  . Make a few more methods const (emu\disound.cpp)
- TMS5110 and YMZ280B sound: Implemented device_clock_changed
- TMS5220 sound: Use device_clock_changed instead of custom method and misc. modernization
- 6532 RIOT: Added some WRITE_LINEs to set individual port lines through callbacks
- 6821 PIA: Logging improvements: Use logmacro.h interface. Removed device tags superfluous with modern logerror. Make LOG_SETUP actually handle something.
- 8253 PIT: Handle slight Faraday FE2010 PIT incompatibility for (MESS) Commodore PC10
- Flash ROM: Fixed global variables (machine\intelfsh.cpp)
- ISA: Added unmap_device method and in install16_device use I/O space width
- Nintendo Custom: Fixed cpu\m6502\n2a03.cpp/h
- NCR 5390 SCSI: Improved initiator transfer information logic. Split transfer count/counter. Added rudimentary 53c90a/53c94 support. Reworked initiator transfer information state machine: should now support all SCSI phases. Improved handling of dma/non-dma commands. Added an undocumented hack to make (MESS) InterPro work. Match updated 5390 device. Inherit memory map. Implemented interrupt status flag in status register for 53c90a, this is critical for (MESS) InterPro. Improved tcounter and dma/drq handling.
- Taito Custom
  . Created C-Chip device with correct CPU type in it and a bunch of notes (pinout etc.) (asuka.cpp, opwolf.cpp, rbisland.cpp, taito_f2.cpp, taito_x.cpp and volfied.cpp)
  . Created a uPD78C11 derived CPU type for this purpose, with internal ROM map.
  . Use internal ROM map for other uPD78C10 chips as it's always present
  . Added missing NO_DUMP definitions to various games using C-Chips with correct size etc. (bonzeadv, megablst, rbisland, superman and volfied)
  . Pump Mega Blast through the device code as really all it ever does is bank the C-Chip window and test the RAM.
  . Load CAPS0ff C-Chip dumps for Operation Wolf and clones, checksum on MASK rom part passes, but game specific EPROM is still bad for the time being. Added small note about what's wrong with the C-Chip EPROM dump.
  . Put C-Chip stuff in Type X driver. Removed outdated comments.
  . Hooked up the four 'asic ram' shared bytes/semaphores/command registers between external cpu and the C-Chip and got rid of the 'return 0x01' hack for Mega Blast (achine\taitocchip.cpp).
- Voodoo GFX: Fixup logging and implement actual vRetrace and hvRetrace functions
- Z80 SCC: Basic wait/dma request implementation. Renamed WRDY to WREQ to match datasheet, minor touch-up.
- atlantis.cpp: Save states supports static vectors natively (machine\vrc4373.cpp). Use actual M48T37 timekeeper. Minor cleanups.
- csplayh5.cpp and niyanpai.cpp
  . Moved around DVD firmwares into 'nichidvd' BIOS set since it's common component. Parallel port is connected, unknown purpose tho.
  . Wrote a new device container for Nichibutsu sound HW, merged usage for csplayh5 and Niyanpai driver.
- crystal.cpp: Document P's Attack edge connector pinout which is non JAMMA. Correct pinout for gun connector & changed JAMMA to 56PIN connector.
- dec8.cpp and karnov.cpp
  . Make DECO RM-C3 (custom palette) into a device and use for DEC8 games
  . All Karnov driver games use the DECO RM-C3 palette. This is really just a documentation change as the previous colour weighting was correct so there is no visual difference with this change.
- decocass.cpp
  . Identified dipswitches for a number of decocass sets
  . Splitted decocass class up so that the dongle types aren't polluting main class and emulate bootleg multigame. Changed accidental drawing order change that was made a while back and broke several games.
  . Added roms from the DECO GRO DE-0091C-1 overlay PCB to Explorer (DECO Cassette) (US)
- docastle.cpp: Weird and inefficient way of reading inputs based on schematics, but code seems to agree. Clarify reset behavior.
- gaelco2.cpp: Fixed protection in Touch & Go and World Rally 2 (Games are now playable)
- galaxian.cpp
  . Clean up driver by using device arrays
  . Added preliminary controls/dips for clone Frogger (bootleg on Amigo? hardware) through I8255 PPI. Game has sound now.
- iteagle.cpp: Save states supports static vectors natively (machine\vrc4373.cpp)
- kinst.cpp
  . Updated hardware info
  . Added AnyIDE roms, switched to BIOS system. Merged Killer Instinct (v1.5d), (v1.3), (v1.4), (proto v4.7) and BIOS (v1.5d AnyIDE) to 'Killer Instinct'. Merged Killer Instinct 2 (v1.4), (v1.0), (v1.1), (v1.3) and BIOS (v1.4 AnyIDE) to 'Killer Instinct 2'. Merged clones Killer Instinct 2 (v1.3k, upgrade kit), (v1.4k, upgrade kit) and BIOS (v1.4k, upgrade kit AnyIDE) to 'Killer Instinct 2 (Upgrade kit)'.
- legionna.cpp and seicupbl.cpp: Initialized tile banks to 0, this should fix problems on Linux & debug builds (includes\legionna.h).
- m62.cpp: M62 proposed cleanups. Splitted the massive PROM blocks up into something more modern looking (the single PROM region with all PROMs crammed into it is an old MAME thing from when only one PROM region was allowed). Made use of multipe palettes and gfxdecode structures (required using RGB32 to draw to). As the boards are quite modular this seems to make sense to me, the palette for the sprites and the sprite decode + sprite palette decode is the same across all games while the rest of the hardware changes a bit. This should allow us to step closer to converting the various boards into devices and piecing them together more logically.
- mappy.cpp: Use LS157 TTL device for DSW2 mux
- namcond1.cpp
  . YGV608 video accessors are 8-bits not 16. Moved a few statics out from r/w handlers. Converted ports to AM_DEVICE.
  . Log registers into own space, handling will follow up. Added CRTC function and moved irqs in handler callbacks. Added preliminary raster irq hookup (limited usage in NCV2).
  . Moved YGV608 base address out of legacy switch case and ROZ registers out of the legacy code. Return h/vblank status bits. Misc IRQ changes. Address pointer clean-ups. Silence some ports in driver.
  . YYGV608 pattern name table pointer access, log mosaic and added border color (makes the POST screens to be black and not green). Added 3rd button.
- neogeo.cpp: Reintegrated NeoGeo romdefs in the source (neodriv.hxx -> neogeo.cpp)
- paranoia.cpp, tourvis.cpp and uapce.cpp: Standardize button layout for Arcade PCE
- segae.cpp: Modernized driver
- stv.cpp: Experimental force resync on DMA completed (machine\saturn.cpp)
- tehkanwc.cpp: Fixed clone Tehkan World Cup (set 4, earlier?) dipswitch setup (different locations populated on PCB?). Hook up DIP locations etc. for all sets.
- usgames.cpp and wallc.cpp: PSG type correction (AY-3-8910A -> AY-3-8912A)
- vegas.cpp
  . Save states supports static vectors natively (machine\vrc5074.cpp)
  . Added I40 board. Added keypad. Use standard way of handling keypad inputs.
  . Mark BIOS in clone 'San Francisco Rush 2049: Special Edition' as BAD_DUMP (ID 06370)
- wrally.cpp: Added PCB layout
- AGEMAME: Put mpu4 back into how it should be (mpu4.hxx -> mpu4.cpp, mpu4avan.hxx -> mpu4avan.cpp, mpu4bwb.hxx -> mpu4bwb.cpp, mpu4concept.hxx -> mpu4concept.cpp, mpu4crystal.hxx -> mpu4crystal.cpp, mpu4empire.hxx -> mpu4empire.cpp, mpu4mdm.hxx -> mpu4mdm.cpp, mpu4misc.hxx -> mpu4misc.cpp, mpu4mod2sw.hxx -> mpu4mod2sw.cpp, mpu4mod4yam.hxx -> mpu4mod4yam.cpp, mpu4sw.cpp -> mpu4sw.cpp and mpu4union.hxx -> mpu4union.cpp)
- Ameri-Hockey and Bozo's Pail Toss
  . Attempt at CPU identification
  . Make some educated guesses regarding manufacturer, decade, MCU and sound chip types. A few technical modifications to Z8 CPU memory interface and added Z8681 type for Ameri-Hockey.
- Arkanoid: Added machine def for "akranoid bootleg with 68705p3 mcu and ay-3-8910" for the ark1ball bootleg, so it has "properly wrong" sound. Added some notes about bootleg roms and what sets they are copied from or derived from. Updated note about hidden credits with hiscore initials.
- Bionic Commando: Fixed screen mis-alignment regression
- Black Touch '96: Various changes/fixes: Added flip screen & coin counter support. Rewritten text layer to tilemap. Added notes on top and promoted game with MACHINE_IS_INCOMPLETE, having many bugs that are actually from very sloppy coding. Converted sound command port to 8-bits and lowered difficulty default (Games now playable).
- Bongo: Map jump as a button and not as up direction
- Candy Crane: Document MCU type that isn't emulated
- Clown Roll Down: Flesh this skeleton driver out slightly
- Crude Buster
  . Fixed colours (verified against real hardware). Added documention.
  . Added a x3 hack to the YM2203 clock frequency to fix incorrect pitch
- Fantasy: Made Fantasy (US) the parent for consistency, since up until now the parent was the German version.
- Fast Lane: Removed imperfect colors flag, Kold verified it and there's no issue with colors.
- The First Funky Fighter: Fixed missing music and partial sound FX (ID 05900). Correct country dipsetting.
- Forty-Love: Clone (Japan) needs MCU double check
- Game Magic
  . Do not always assert on unimplemented PCI configuration registers (Intel 82439TX Northbridge; bus\lpci\i82439tx.cpp). Log a message in the error log instead. Also put writes to 0x58 and 0x5c in their own case. Give derived classes the ability to intercept writes to debug port 0x80 (lpci\southbridge.cpp). Added boot_state_hook devcb to receive writes to debug port 0x80 (lpci\i82371sb.cpp).
  . Splitted the single rw handler to io ports 60 and 61 into two separate handlers one for each port. To support systems in the future where the southbridge does not contain a keyboard controller (lpci\southbridge.cpp).
- Gladiator: Inverted coin counters and minor HW note
- Golden Axe: Replaced bad dump 317-0122 i8751 MCU in clone Golden Axe (set 2, US) (8751 317-0112) with working redump from undamaged chip. Removed MCU HLE code.
- Gun & Frontier: Correct 'Upright Controls' dipswitch - OFF is Single, and should not be the default.
- Lady Bug: Documented a different program ROMs arrangement
- Levers and Nibbler: Changed joysticks to 4-way as documented in manuals
- Mahjong Chinmoku no Hentai: Removed DSW B, this does not exist on a real PCB (ID 06592).
- Marchen Maze: Added default NVRAM
- Master Boy: Use parallel EEPROM type for "EAROM" rather than generic NVRAM
- Mega Double Poker: Load recent CAPS0ff 68705P5 MCU dump for Mega Double Poker and clone. Hook up 68705P5 MCU, figure out banking and added timekeeper RAM and inputs. Merged driver with Golden Poker driver to get working sound (graphics and sound should be identical) (Game now playable).
- Miss Bubble II: Fixed OKI read/write bitswap so what seem to be the correct sound effects are played. Used the OKI rom from clone 'Bubble Pong Pong' in place of the badly dumped missb2 OKI rom due to all non-corrupted areas being identical, so they're most likely supposed to be the same, but marked it as BAD_DUMP until redump. Added watchdog (same as parent bublbobl hardware has).
- Mr. Do!: Load protection PAL data (not used at the moment)
- N.Y. Captor: Fixed colors in clone Colt
- Ninja Clowns: Fixed potentially crash during fighting the final boss 'Twisto'. The blitter code was writing outside the limits of the VRAM (ID 06620).
- Omega: Dumped the color proms correcting the colors. Minor updates to dipswitches. Set default values for unknown dipswitches to "Off". Correct coin counter polarity; name config structures more consistently.
- PinMAME
  . joctronic.cpp: Added new maincpu to Punky Willy. Callback modernization for its own sake.
  . wpc_dcs.cpp: Added new DCS roms to Judge Dredd (L-7) and clones (L-4), (L-5) and (L-6).
  . flicker.cpp: Added save state support. Removed NVRAM - it's unlikely a dynamic PMOS RAM would be battery-backed. Hook up the rest of the inputs (operator adjustments). React to input changes on test line. Added notes. Re-implemented I/O based on how hardware actually works. Corrected RAM size. Hooked up playfield lamp outputs - this really needs PWM.
- Pole Position II: Fixed crowd cheering sounds are messed up at the chequered flag goal (ID 06261)
- PT Reach Mahjong: Added samples. Driver cleanup.
- Quest of D (CDV-10005C): Added Firmware Update DVD dump
- Return of the Invaders
  . Added original Taito 68705 MCU dump and moved bootleg 68705 MCU to its own new set. Renamed sets to make it more obvious which are bootlegs. Verified XTAL, dividers and SN76489A type from PCB pictures. Added missing original Taito CLUT PROMs and fixed video driver to be able to use those or the single bootleg CLUT prom.
  . Added DIP locations and document edge connectors
- Rod-Land: Added information regarding clone R&T (Rod-Land Prototype) (see http://sudden-desu.net/entry/rod-land-location-test-code-and-stage-editor)
- Ron II Mah-Jongg: Ron II actually works, promoted to working.
- Rotary Fighter: Added PPI and coin counter
- Schmeiser Robo: Game sets rowscroll to be bigger than assumed size of tilemap. This fixed exception on exit on Linux 64bit and Windows XP (ID 06613).
- Sega Ninja: Decrypted SEGA 315-5133 used by clone Sega Ninja (315-5113), promoted it to working. Exactly the same as Sega 315-5048? with a different number.
- Shoot Away II: Added AT28C64 EEPROM
- Soreike Kokology Vol. 2: Redumped sound data ROM. Fixed missing voice (ID 06627).
- Steel Force: Switched to OKI map instead of ROM_COPY
- Super Real Darwin: Use CAPS0ff dump for Super Real Darwin. Handcraft MCU rom for clone Super Real Darwin (Japan) like was done for other games in the driver so the old sim can be killed off, marked as BAD_DUMP. Seems stable, although I had to boost the interleave. Note: This game has never been emulated correctly.
- Superbike: Kludged a protection check that was resetting the machine under certain conditions. Also demoted to MACHINE_UNEMULATED_PROTECTION since game can lock indefinitely under a specific case scenario.
- Target Hits: Added PCB layout and base CPU clocks on actual OSC/Resonator. Corrected OKI clock and program rom labels.
- Time Limit: Redumped color proms. Promoted colors after counter-check with real screens.
- Tsukande Toru Chicchi: Added dipswitches
- Victory: Added PIO devices
- Victory Road: Added PALs
- Save state
  . Reintroduced a state save menu: * This turns the current state save feature to a menu; one can still press 0-9, but you can also browse a menu when loading and saving state. * Fixed some issues requested by Vas Crabb. * Updated state menu to support arbitrary character slots. * WIP, transitioned 'entry_char' to std::string. Still need to address Joystick and FR keyboard concerns. * Reimplemented state save support with joystick buttons. * Changed the state menu to be "code driven" rather than "character driven". When the menu is displayed, it will look at the filenames, and translate them to a visual representation as per the user's locale. * Vas feedback. Fixed state save menu UI issues.
  . Moved save state registration to interface post start. Plays nicely with device_missing_dependencies exceptions. Frees implementation from having to call save state registration method. Improved save state support in devices that neglected to call method.
  . Explicit sizes for enums and enum class used in save states, one should always do this to maximise save state compatibility. Fix up a couple in src\mame as well.
- Dipswitch fixes in decocass.cpp, ddenlovr.cpp, freekick.cpp, galaxian.cpp, konmedal.cpp, m14.cpp, taito_f2.cpp, tehkanwc.cpp and vegas.cpp
- Fixed rom names in retofinv.cpp, stv.cpp and targeth.cpp
- Description changes of Cobra-Command (World/US revision 5), The First Funky Fighter (USA, Canada, Mexico / Japan, set 1), The First Funky Fighter (USA, Canada, Mexico / Japan, set 2), Lee Trevino's Fighting Golf (World?), Lee Trevino's Fighting Golf (US), Lee Trevino's Fighting Golf (US, Ver 2), Killer Instinct, Killer Instinct 2, Killer Instinct 2 (Upgrade kit), Logger (Rev.3), Mega Double Poker (conversion kit, version 2.3 MD), Mega Double Poker (conversion kit, version 2.1 MD), Motocross Go!

- Renamed (actfancr) to (actfancr2), (fantasy) to (fantasyg), (kageki) to (kagekiu), (kinst2k3) to (kinst2uk), (retofinv1) to (retofinvb1), (retofinv2) to (retofinvb2), (sderby2) to (sderby2s), (striv) to (strivf) and (xevi3dg) to (xevi3dgj)
- MAME
  . UI
    . Overhaul to how MAME handles options. This fixed loading softlist items from the command line with changed slot options (ID 06588) and various problems with software loading/unloading (ID 06581). Set the value when setting the default as before (util\options.cpp)
    . Fixed options regression (ui\selsoft.cpp)
    . Allow experimental overclocking of sound devices through UI sliders with -cheat enabled (ui\ui.cpp)
    . Fixed slot unmount issue: Start (MESS) mame sorcerer, then enter the slots menu, empty the RS232 slot, then choose Reset. It crashes with an access violation (emu\image.cpp).
    . Make internal UI display list of missing files if system/software set is found but incomplete. Also consolidated selgame/selsoft code for actually launching systems into one place. Reduced header clutter (ui\selmenu.cpp).
  . Added YMF271 and YMZ280B support to VGM player
  . DEVICE
    . Fixed issue loading reset_on_load() images (emu\diimage.cpp). Fixed custom instance names and slot devices don't work properly with the current MAME options code (emu\diimage.cpp).
    . Fixed scheduler overflow when a device executes for more cycles than there are in a second
    . Improved the speed of romident by dynamically allocating some large device member arrays at device_start time instead (sound\ay8910.cpp, audio\taito_en.cpp and video\powervr2.cpp)
    . Fixed Clang build (emu\device.h)
    . Lift the cap on the number of address spaces per device (emu\dimemory.cpp). Make device_memory_interface slightly less of a special case, use a typedef to avoid nested templates everywhere. Make device_memory_interface own its address_spaces. Kill a trampoline (memory.dump(); debug\debugcmd.cpp and emu\emumem.cpp).
    . Make machine().describe_context() a const function returning a std::string. As part of this change (because std::string is not printf-compatible), several devices have been updated to use the modern logmacro.h logging system.
  . Don't lose the system inipath when looking for hashpath (mame\mameopts.cpp)
  . PLUGINS
    . Fixed NESS Game Genie decoder and link simple cheats (plugins\cheat\cheat_simple.lua). Added UI support for joystick hotkeys (plugins\cheat\init.lua). Poll for setting hotkeys. Create dirs. Popmessage for hotkey setting.
    . Updated hiscore.dat
  . Initialization ordering fixes (emu\emumem.cpp/h and machine.cpp)
  . Removed redundant flags MACHINE_NOT_WORKING and MACHINE_NO_SOUND and replaced them with MACHINE_IS_SKELETON.
  . Fleshed out network output provider so it has the same capability as legacy Win32. Clients: Connect to TCP port 8000. Messages will be of the form "verb = value\1"; if your client is busy when MAME is spamming, you may get multiple messages glued together by \1 separators. (\1 was chosen because it's neutral on Win32/Mac/Linux). You will get a "hello = 1" message upon connection to MAME, and a "mamerun = 0" message when MAME shuts down. You may send "send_id = n" to MAME to get IDs where n=0 means ROM set name of current game, 1-? = output node names. MAME will reply "req_id = string\1"; this is currently the only case where a string will be returned instead of an integer value. A working example POSIX client will be released soon (output\network.cpp).
  . Include -output option in documentation (docs\source\commandline\commandline-all.rst)
  . XML listing enhancements: The -listxml command will try to find and list any devices whose shortnames are specified on the command line. Any number of devices can be listed at once, and wildcards will be compared against device names as well as driver names. DTD output for -listxml, -listsoftware and -getsoftlist can be disabled by a new -nodtd option. It remains enabled by default.
  . Better handle the case where HTTP is not enabled (emu\http.cpp)
  . Switched to delegate timers. Frees implementations from having to call timer method. Eliminates risk of ID conflicts with implementations/other interfaces.
  . Layout
    . Do substantial validation of internal layouts at build time (scripts\build\complay.py). Removed vestigial exception class. Comment out problematic parts of internal layouts detected by build-time validation (layout\checkma5.lay, mmerlin.la and tisub.lay)
    . Don't drop an entire layout if one view fails to load - it breaks (MESS) intlc44/intlc440 with null_modem (emu\rendlay.cpp)
    . Changed backslash to unicode in some layouts
  . Detect parent/clone loops rather than extending a string forever (emu\driver.cpp)
  . Validity: Removed validation check - it causes MSVC release builds to crash, and the things it flags usually get detected elsewhere (emu\validity.cpp).
  . VGM player
    . Added sound cores needed to allow virtual subtarget to compile (YMF271 and YMZ280B; scripts\target\mame\virtual.lua)
    . Fixed playing .vgm/.vgz files containing 2 X POKEY (ID 06631). Fixed clock speed for dual POKEY. Produce error message when nonexistent file specified rather than create a spurious empty file and segfault trying to read it.
  . LUA engine: Safer cleanup and fixed leak
  . Changed Romload to show all actual hashes on a mismatch
- SDLMAME
  . Added SDL_WINDOW_BORDERLESS for fullscreen, required by some window managers on Linux. Breakage was in MAME 0.160.
  . Fixed sound_sdl::sdl_callback, fill buffer with silence when underflow. The problem is most noticeable when you are saving state and the save takes a relatively long time, short period of audio gets played repeatedly, which is usually unpleasant. I found out it's caused by sdl_sound::sdl_callback not fill the audio buffer with silence when underflow occurs. According to https://wiki.libsdl.org/SDL_AudioSpec, if there's nothing to play, the callback should fill the buffer with silence. I tested this change and the problem is gone.
  . Updated Fedora instructions. DNF is now preferred package manager. alsa-lib-devel is also required (not mentioned in the current docs) (initialsetup\compilingmame.rst).
- MAC OS X
  . Added basic support for saving/restoring Cocoa debugger window state, compatible with Qt debugger where possible.
  . Fixed some Cocoa debugger desync issues. Scroll to selection on gaining focus by keyboard (e.g. tab) only. Fixes jump on clicking a memory or disasm view that you've scrolled.
- Compiling
  . Fixed tiny build (missing Z80PIO; scripts\target\mame\tiny.lua)
  . Renamed AS_DECRYPTED_OPCODES to AS_OPCODES
  . C++14 constexpr doesn't cooperate with universal references (bus\isa\isa.h, machine/gt64xxx.h, pci.h, vrc4373.h and vrc5074.h)
  . Clean up inlines for MSVC. No reason to prefer inline assembly over MSVC _BitScanReverse intrinsic on x86 (osd\eivcx86.h)
  . c_str() is no longer needed with emu_file::open since it now takes a std::string (emu\machine.cpp)
  . Fixed save/load states in Emscripten build. Simplified Emscripten integration points. Moved standalone JS functions to be static member functions of running_machine. Improved Emscripten main loop. Use convenience functions for cleaner code. As an added bonus, this now allows for proper shutdown of the running machine when running in the Emscripten environment - previously, attempts to exit the program were just being ignored. Export soft_reset, hard_reset, exit, load and save functions for Emscripten builds (scripts\resources\emscripten\emscripten_post.js)
- Debugger
  . Simplify by decoupling information creation and display rendering (debug\dvdisasm.cpp)
  . Eliminated direct() from read_opcode (debug\debugcpu.cpp)
  . Reverted debugger F8 behaviour, to run until next start of vblank, by re-adding a check that was removed in MAME 0.175.
  . Made the debugger 'load' length field be optional, C++-ification.
