- New drivers: video21.cpp
- Removed games: River Patrol (bootleg set 1)
- New devices: gt64111, mp1210, namco_c123tmap, namco_c169roz, namco_c355spr, namco_de_pcb, namcos21_3d, namcos21_dsp_c67_device, namcos21_dsp_device, namcoc65, namcoc67, namcoc68, namcos2_roz, namcos2_sprite, pssj3, r4000be, r4000le, r4400be, r4400le, rs232_mouse_hle_logitech, rs232_mouse_hle_wheel and rs232_mouse_hle_rotatable
- MIPS 3/4 CPUs: Implemented DMULT and DMULTU. Added R4000 and R4400 variants.
- PSX CPU: Converted PSX SIO to DEVCB3
- Zilog Z8681 CPU / Z8 CPU
  . Fixed detection of stack type and JP @ and CALL @ instructions (cpu\z8\z8.cpp)
  . Added DA instruction (Decimal Adjust). Fixed numerous bugs. Now all 4 machines in (MESS) jtc.cpp are pretty much working now.
- Exidy SFX sound: Get rid of double TMS5220 device read
- N2A03 APU sound: Removed read/write trampolines and zero $4015 at reset https://wiki.nesdev.com/w/index.php/CPU_power_up_state
- SN76496 sound
  . Renamed NCR7496 to NCR8496 for Tandy 1000TX and similar machines based on PCB pictures and service manual parts list.
  . Added support for PSSJ-3 ASIC used in later Tandy 1000 machines. Fixed noise generatior behavior in NCR8496 and PSSJ-3 to match hardware tests.
- TMS5220 sound: Removed read/write handler trampolines
- CD-ROM: Accept .toast as a synonym for ISO images (util\chdcd.cpp)
- EEPROM: Added AM28F020
- Floppy: Sectors must be read even if it contains Deleted Mark. FDC will read the data if SK bit is not set (formats\dsk_dsk.cpp). Fixes some disk games gives error when running in (MESS) Amstrad CPC6128.
- Intel 8251 USART: Provided standard read/write handlers and eliminated memory space as argument
- MC6840 PTM
  . Fixed output pins in Dual 8 bit mode. In Dual 8 bit mode the output isn't inverted on every TC, instead it's low until the count reaches 0xff, and high afterwards.
  . It's generally not a great idea to do integer ops on bool - it implicitly casts to/from int and may perform poorly (machine/6840ptm.cpp; ptm6840_device::timeout).
- Mouse
  . Re-write serial mouse support
    . Splitted Microsoft mouse into separate two-button (Microsoft), three-button (Logitech) and click wheel devices. 
    . Added Microsoft wheel mouse. Made Mouse Systems mouse behaviour better match early Mouse Systems models,
    . Added "rotatable" Mouse Systems mouse support (untested due to lack of software)
    . Simplified code and eliminated timers
  . X/Y translation and buttons works for all devices. The wheel on the wheel mouse seems to be transmitting the right data, and CuteMouse detects the wheel as being present, but no software seems to support it properly. Software supporting the Mouse Systems "rotatable" mouse is very rare - typically people just set the DIP switches on their M-1 for "non-rotatable" mode. A standard mouse driver will see the "rotatable" mouse moving two mickeys for each count, and move eratically on rotation. The "rotable" mouse is poorly tested due to lack of software.
  . MAME doesn't have a proper input type for a mouse wheel, and it doesn't seem to be possible to map the host mouse wheel to an axis when configuring inputs. The default mapping ends up assigining the wheel or rotation to one of the translation axes, which is very unhelpful.
- PowerVR 2
  . Store different types of polygons in different lists
  . Make opaque polygons opaque. Previously, MAME's PowerVR 2 implementation treated all polygons as transparent. This resolves missing graphics in certain games which were rendering opaque polygons with alpha values which would make them transparent if they weren't on the opaque list. In the future, punch-through polygons will also require special consideration. These are polygons which support transparency but not blending (every pixel is either entirely transparent or entirely opaque). For now, they're still treated the same as transparent polygons.
- PSX GPU
  . Added textured dot rendering (video\psx.cpp). Fixed building with PSXGPU_DEBUG_VIEWER.
  . Implemented transparent dots & lines and declare variables on first use.
  . Implemented GPU STP draw and checking, which is used on Aquarush for water effects.
- SCSI Hard Disk: Added FORMAT_UNIT command to machine\nscsi_hd.cpp
- Seta SETA001 Sprites: Removed a sprite drawing kludge
- Signetics SCN2674 AVDC: Added hack to allow (MESS) PC-X to get its first interrupt and make PC-X display work again in new resolution
- Timekeeper: Switched to use the new logmacro system. Fixes issue that could cause updates to be missed.
- Z80 DART: Default RXD to 1 to eliminate spurious break condition. Correct CTS level in RR0 after "Reset External/Status Interrupt" command. Allow immediate inactivation of RTS output when nothing is being transmitted.
- 1945kiii.cpp: MCFG cleanup
- artmagic.cpp: Reduced runtime tag lookups. Cleanup naming etc.
- astrocde.cpp: Fixed bad format string (includes\astrocde.h). Fixes a debug assertion in Ten Pin Deluxe (ID 07090).
- bartop52.cpp: Get rid of required ram_device in Atari 8-bit common state - it isn't required/used by Bartop5200 driver and get rid of bogus RAM device in Bartop5200 driver.
- by35.cpp: Syncing with PinMAME. Added new cpu2 rom to Dark Shadow and Super Bowl. Marked Top Pin sound1 rom as BAD DUMP.
- coolpool.cpp: DAC type identification
- crospang.cpp
  . Fixed tile banking which should fix some Bestri bugs
  . Fixed Bestri gfx1 rom loading
- dkmb.cpp: Added notes
- dreamwld.cpp: Fixed rowscroll
- fuukifg2/3.cpp: Fixed damage/tilemap buffer offset
- gaiden.cpp: Reverted type of still-undumped MCU. Note: The location of the protection MCU (right next to the DIP switches, and not populated on Ninja Gaiden) is marked µPD8049 on the PCB. This has found to actually be a 8749 (internal EPROM type) on Raiga and Tecmo Knight/Wild Fang.
- gal3.cpp, namcofl.cpp, namconb1.cpp, namcos2.cpp and namcos21.cpp
  . Converted Namco C65, C67 and C68 to devices for namcos2.cpp and namcos21.cpp. Some cleanup.
  . Use configured banking for audiocpu for namcos2.cpp and namcos21.cpp
  . Splitted Namco C169 ROZ chip, C123 tilemap chip and C355 sprite chip from namcos2 shared state by making them devices.
  . Untangle gal3, namcofl, namconb1 and namcos21 from namcos2 now that things are devices
  . Splitted namcos21.cpp into 3 drivers as the different configurations really are entirely different boardsets with similar components, not a real 'system' emulated entire PCB set for Driver's Eyes (http://www.tvspels-nostalgi.com/Bilder/PCB/Namco/driverseye_cage_inside.jpg) although how the PCBs communicate is not yet known (C139 maybe, which might also be an MCU).
  . Survived F3 resets without crashing or breaking the 3D (machine\namcos21_dsp_c67.cpp)
  . Moved 3D code into device (video\namcos21_3d.cpp). Splitted DSP support code into device (machine\namcos21_dsp.cpp). Moved code for C67 based DSP PCB into it's own device (machine\namcos21_dsp_c67.cpp).
  . Added default NVRAM to Dirt Fox and Driver's Eyes, Winning Run, Winning Run '91 and Winning Run Suzuka Grand Prix
  . Added new maincpu roms to clone Four Trax (US?, censored banners) and use correct slave roms. The old dump of this set only differed in having a 0x00 fill in the 2nd half instead of a 0xff fill.
  . Give Galaxian 3 some DSPs. Splitted C355/palette/GFX decode/video functions related to obj-board and each screen. Added save state. Minor cleanups.
  . Fixed Lucky & Wild damage due to bad ram size assumptions
  . Added PLDs to clone Rolling Thunder 2 (Japan)
  . Restored CPU yield hack for Solvalou
- namcos22.cpp: Fixed SS22 text layer alpha blending (eg. Alpine Racer highscore table and Air Combat 22 radar). Added limits to Air Combat 22 analog controls, also let's just mark the game as working.
- galaxian.cpp
  . Start moving memory stuff out of init functions and into address maps
  . Converted driver to use MCFG_SCREEN_VBLANK_CALLBACK
  . Fixed protection in 'The End'. 'The End' now shows the HIT UFO screen after the CHANCE TIME round.
  . Corrected Jump Bug background hardware behavior, as per real hardware. Stars actually show up until the 232nd pixel.
  . Corrected bullet behavior and protection in Scramble. Shells are now two pixels long and have been verified on real hardware.
  . Corrected background hardware on SF-X and Monster Zero to now show stars and RGB backgrounds. Colors may not be correct, and the current schematics scans are not easy to read.
  . Moved Scorpion's extra ROM and sound handlers into address maps
  . Added correct MACHINE_CONFIG_START to clone Frog (Galaxian hardware)
  . Added necessary extra sprite RAM to address map for Time Fighter (Time Pilot conversion on Galaxian hardware) and PSG reads for good measure.
  . Fixed (?) clocks on Jungler (Subelectro, bootleg on Scramble hardware). The Subelectro 113 board has no XTALs, and I am assuming the CLK lines come from the pixel clock on the Konami L-1200-2 board.
  . Corrected sync and machine setup for Take Off, Explorer and Amigo (bootleg of Amidar, set 2). Sidam bootlegs of Konami games have a 12MHz pixel clock with video being scaled by two pixels instead of 3. All are now correctly set up as per the 12 MHz pixel clock.
  . Mark Explorer and Amigo (bootleg of Amidar, set 2) as MACHINE_IMPERFECT_SOUND. Explorer requires the same sound timer as Take Off, which I have no idea how it works. The latter probably has a similar case, although it might be different from Explorer.
  . Mark Take Off as MACHINE_WRONG_COLORS. See the reference video for more; some colors that are purple with the default palette_init are green on real hardware.
  . Given Take Off's hardware hierarchy, correct the year from 1980 to 1981 as a guess.
  . Turpin (bootleg on Scramble hardware) is likely more derived from Super Cobra hardware than Scramble hardware. Changed the set description to match this statement.
- iteagle.cpp, seattle.cpp and vegas.cpp: Changed readback value of PCI config 0x40 based on Voodoo card type (video\voodoo_pci.cpp). Fixes NFL Blitz hangs on a black screen if the power on self test is enabled (ID 06874).
- konamigq.cpp, konamigv.cpp, ksys573.cpp, namcos11.cpp, namcos12.cpp, taitogn.cpp, twinkle.cpp and zn.cpp: Moved imperfect graphics flag down into PSX GPU device (video\psx.h)
- konamigx.cpp: Updated documentation
- lethalj.cpp: Reduced runtime tagmap lookups and improved function and region naming
- mcr.cpp and mcr3.cpp: Set midway_ssio_device pointer to NULL. This fixed debug assertion failed! Expression: m_target (ID 07085).
- mcr68.cpp
  . Fixed MC6840 PTM output pins in Dual 8 bit mode. In Dual 8 bit mode the output isn't inverted on every TC, instead it's low until the count reaches 0xff, and high afterwards. This fixed Xenophobe doesn't start.
  . Mapped MC6840 to lower data bits on all MCR68 games, which matches the Blasted schematics. I used cswidth as different games write at odd or even addresses, even though the boards look visually similar. Byte writes will work in either case as the MC68000 puts the same data on the upper and lower part of the bus. Reads are a mix of odd and even addresses, clone 'International Team Laser' and Spy Hunter II exclusively read at even addresses. It's unclear whether this is a bug in those games or not.
- megatech.cpp: Added cart label numbers from manual

- neogeo.cpp and neopcb.cpp
  . Dumped sp1-u4 BIOS from a US 4-slot MVS

  . Fixed crash when fix BIOS is not exists (video\neogeo_spr.cpp)
- nmg5.cpp: Added copybitmap_trans for bitmap layer. Cleanup duplicates/ACCESSING_BITs and filling bitmap layer.
- psikyo.cpp: Fixed rowscroll (video\psikyo.cpp). This fixes bad glitch graphic on some stages in Tengai and clone (ID 07076).
- raiden2.cpp
  . Group Raiden 2 / DX sets by code revision so that we can more easily see which just differ by region byte, make it clear what features determine game type (normal, easier, harder).
  . Fixed OKI6295 clock and pin7 level for Zero Team and clones New Zero Team and Zero Team 2000
- seta2.cpp: Added P0-113A PCB layout and note about undumped version of Guardians using this board
- taito_b.cpp: Removed MCFG_SCREEN_VBLANK. One less callback to configure (video\tc0180vcu.cpp).

  . Complete redump of clone Cool Minigame Collection (Italy)
- vegas.cpp
  . MCFG removal and define device clock and use derived clock for UART (machine\vrc5074.cpp)

  . Removed no sound flag from clone Gauntlet Legends (version 1.2) as I couldn't find any major sound bugs in recent versions
  . Added imperfect sound flag to sf2049 and clones, nbashowt, nbafl and nbagold (previous flagged as no sound).
- vpoker.cpp: 6809 type identification
- yunsun16.cpp: Cleanup tilemap scanning and duplicates. Reduced runtime tag lookups and unused members. Fixed notes.
- 3 Super 8 (Italy): Fixed palette related crash and removed MCFG macros
- Aquarush: Implemented PSX GPU STP draw and checking, which is used on Aquarush for water effects.
- Beast Busters
  . Fixed sprite priority. Credit to Daniel Filner for information. Palettes 0xc-0xf on 2nd sprite chip behind the tilemap - confirmed on level 2 and matches real hardware video. Removed imperfect_graphics flags as no open bugs.
  . Use single pass sprite render with priority buffer in case of cut-out effects
  . Removed imperfect sound. Reference video at https://www.youtube.com/watch?v=i3txCb5tpkc

- Lucky Ball 96
  . Banking, inputs, demux and a lot of work to get the game working properly.
  . Rewrote of the whole multiplexed input system as requested, and standardized each input. Also explained some things about the hardware behaviour. Cleaned up the driver. Added DIP locations and ASCII diagram of Inputs/Outputs through 3x 4099 addressable channels and 3x 4512 data selectors.
  . Changes to the memory map and banking after an exhaustive hardware analysis
- Midnight Landing: Updated PCB layout and derive clocks based on actual OSC
- Mighty Monkey: Fixed mirroring for video writes for clones Mighty Monkey (bootleg on Scramble hardware) and Mighty Monkey (Kaina Games, bootleg on Scramble hardware). Score is now displayed correctly.
- Operation Wolf
  . Moved C-Chip simulation out of driver and cleaned up code.
  . Added speaker volume control (global fade in/out at intermissions) and ADPCM sample volume control
  . Use Z80 for clone Operation Bear (bootleg of Operation Wolf) to read inputs instead of directly mapping them.
- Pac-Land
  . Fixed the difference with real hardware: Fixed incomplete priority of sprites on foreground and sprites could not be displayed at the bottom of the screen.
  . Changed driver to approach real hardware behavior
- Pipi & Bibis / Whoopee!!: Bootleg clone has different clocks
- Primal Rage 2: Hooked up watchdog
- Quest of D Oukoku no Syugosya: Brute forced security key
- R-Type II: Added PAL dump to clone (Japan)
- River Patrol: Added correct gfx2 rom to parent set
- Speed Ball - Contest at Neonworld: Fixed P1 START key
- Steel Gunner 2: Make SET instruction in Mitsubishi M740 subfamily actually affect execution (cpu\m6502\m740.h). This fixes missing P1/2 coin buttons in Steel Gunner 2, and may fix subtle problems in other drivers as well (ID 07091).
- Super Shanghai Dragon's Eye
  . Improved video mixing and palette handling. This fixes sprite priority bug with the ingame message boxes (ID 05904) and black sprites in some cutscenes (ID 06020).
  . Fixed OKI clock/pin7. Reference video at: https://www.youtube.com/watch?v=buCb-exoJWo
  . Added save state support and removed MCFG macros
- Target Hits: Fixed Player 2 Light gun control (ID 07092)
- Thunder & Lightning: Restored (bootleg with Tetris sound) to previous working state
- Tumble Pop
  . Improved documentation for clone Tumble Pop (bootleg with PIC)
  . Gave clone Tumble Pop (Playmark bootleg) it's own memory map, adjusted spriteram location.
- Valtric: Redumped gfx3/text rom vt_07.bin. The rom was overdumped (although both halfs were not identical, having two different bytes). The rom socket on the PCB was labeled as "27128", pointing that the new size is the right one.
- Zen Nippon Pro-Wrestling Featuring Virtua: Clone (T 971123 V1.000) runs only with Taiwanese BIOS
- Fixed year info for chessc2 (ID 05059), denjinmk and heuksun

- MAME
  . VIDEO RENDERING SYSTEM
    . HLSL
      . Apply scanline effect before defocus effect and moved scanline effect into separate shader. Port scanline modification to BGFX.
      . Fixed not set default uniforms for vector pass (render\d3d\d3dhlsl.cpp)
    . A better way of doing scanline timers (machine\timer.h; (MESS) apple2e.cpp)
    . Generate layouts for dual-screen machines rather than loading dualhsxs.lay. This ensures aspect ratio is correct for non-4:3 screens (emu\render.cpp).
    . Allow watchdog timer to take any tag-like for the screen tag rather than only C strings (foodf.cpp, galaga.cpp, gottlieb.cpp, grchamp.cpp, mcr3.cpp, missile.cpp, polepos.cpp, rampart.cpp, sbrkout.cpp, sprint2.cpp, sprint4.cpp, tecmosys.cpp, toobin.cpp and ultratnk.cpp)
    . Fixed palette-related asserts in ddragon.cpp, efdt.cpp, peplus.cpp, royalmah.cpp, spoker.cpp, system16.cpp, taito_h.cpp and wardner.cpp
    . Replaced a fail-safe in util\palette.cpp with an assert. Expect regressions, so better to get it out of the way now.
    . Added read functions for paletteram_ext (emu\emupal.cpp)
  . DEVICE
    . Fixed ioports/membanks in internal maps (emu\device.cpp and emumem.cpp)
    . Fixed unmapped values with subunits (emu\emumem_heu.cpp)
    . Removed MCFG usage in hotstuff.cpp, micro3d.cpp, machine\i2cmem.h, i8212.h, i8243.h, i8251.h, i8255.h, i8257.h, i8279.h, intelfsh.h, ins8154.h, ins8250.h, iteagle_fpga.cpp, k033906.h, k053252.h, k054321.cpp, k056230.h, latch8.h, m6m80011ap.h, mb14241.h, mb3773.h, mb89363b.h, watchdog.h, wd33c93.h, mc146818.h, mc2661.h, v3021.h, x76f041.h, x76f100.hm z80ctc.h, z80daisy_generic.h, z80dart.cpp, z80dma.cpp, z80pio.h, z80scc.cpp, z80sio.h and video\v9938/v9958.cpp
    . Don't abuse object finders for things that can't be found at object resolution time
    . Separate out screen device in konamigq.cpp, konamigv.cpp, ksys573.cpp, namcos10.cpp, namcos11.cpp, namcos12.cpp, psx.cpp, taitogn.cpp, twinkle.cpp and zn.cpp
  . PLUGINS: Fixed memshares and aligned search option in plugins\cheatfind\init.lua
  . Eliminated savestates register_postload in sound\msm5232.cpp, okim6376.cpp, spkrdev.cpp and vlm5030.cpp
  . Eliminated register_postload from video\k052109.cpp, k053251.cpp, k054156_k054157_k056832.cpp, pc080sn.cpp, tc0080vco.cpp, tc0100scn.cpp, tc0110pcr.cpp, tc0480scp.cpp and ygv608.cpp
  . Network: Changes to make (MESS) InterPro networking work on Windows with the TAP-Windows6 driver: Pad short Ethernet frames and append FCS (Windows-only until Linux taptun behaviour is verified) (netdev\taptun.cpp). Fixed bugs in carry flag handling, prefer sign bit for tests (clipper). Introduced somewhat realistic delays into network transmit and receive paths. This version works by adding functions to device_network_interface which enable a device to be informed when the transmit or receive completes. The delay is only crudely approximated based on the specified bandwidth and the number of bytes being transmitted, but it should be good enough in practice. Existing drivers should not be impacted by these changes; overriding the new functions (and no longer overriding recv_cb) is necessary to obtain the new behaviour. Added transmit/receive delay timers, handlers and logic (emu\dinetwork.cpp). Added the ability to start the receive timer (osd\osdnet.cpp).
  . Software List: Fixed displaying of software lists title images (ui\selmenu.cpp) (ID 06998)
  . Updated hiscore.dat (plugins\hiscore\hiscore.dat)
  . Multi-Language: Updated Korean translation translation
  . Added missing short commands (docs\source\commandline\commandline-all.rst)
- VGM player
  . Added support for HuC6280, Sega 32x, SN76496, YM2203, YM2608, YM2610, YM2612 and Y8950 sound
  . Added detection of bad NES rips where no audio channels are enabled. Updated messages to make it clear that the hacks are required due to bad rips. When a bad 32x rip is detected then both the left and right channels are enabled.
  . Report incorrect header size and replace with default
- Compiling
  . Workround so you can still compile if you install the Visual Studio 15.8 update, as long as you install the 14.14.26428 compiler as well (3rdparty\genie\src\actions\vstudio\vstudio_vcxproj.lua and 3rdparty\genie\src\host\scripts.c).
  . Set Visual Studio to 64 bit by default (3rdparty\genie\src\actions\vstudio\vstudio_vcxproj.lua). Enabled edit and continue in Visual Studio debug builds (scripts\genie.lua)
  . Restored some authors' stylistic choices. Make some stuff more consistent. This fixed debug assertion in aristmk4.cpp, bagman.cpp, gts3a.cpp, mac.cpp, pacman.cpp and others (ID 07089).
  . Fixed lots of inadverently mutable static pointers
  . Fixed inadvertently non-const pointers - emu.h edition (lib\util\hash.cpp). This fixes all the non-const pointers with static lifetime I could find with a cheap grep (in combination with the last commit). There are likely more lurking that I didn't find, and things that aren't pointers that should be made const. There are still a few mutable static pointers that break the ability to host multiple drivers but these require refactoring to fix.
- Debugger: Fixed debugger memory view editing for address-shifted spaces

- MOS Technology M6502 CPU: Allow debugger to step over CALLF instruction (m6502\m6502make.py)
- Motorola MC68000 CPU
  . Fixed andi, ori and eori instruction. From https://github.com/kstenerud/Musashi/commit/df0fb402a8042c964a70cb987fe6f27ff96952ef and a16bd2bb289ea2cdbb1ca11a997490774eb32b5e.

    . Added Special Status Word (SSW) to exception frames
    . Throw MMU configuration exception if SRP/CRP is invalid
    . Deduplicated code to set buserror details. Factor out ATC lookup into pmmu_atc_lookup().
    . Cleanups. Factor out TT register matching into pmmu_match_tt(). Simplify tt/fc matching. Removed dead code. Factor out table walking code. Replaced printf by logerror. This should be switched over to use LOG(), but can't right now because the header file is included directly in C++ classes.
    . Support short indirect descriptors and set MMU status flags in pmmu_atc_lookup(). This makes the (MESS) HP-UX 9 installer boot. Also tested that the following systems still work: Macintosh IIx with Mac OS 7 and HP-UX 7.
    . Don't try to read address bits in indirect descriptors as status bits and initialize m_mmu_tmp_sr before doing a table search. With this commit, everything required to run HP-UX 9 in mame is upstream. Tested the following machines with this mmu change: maciix with Mac OS 7, hp9k360 with HP-UX 7, HP-UX 9 and the HP-UX 9 installer.

  . Remember m_allpot_r_cb() value
- Irem GA20 sound
  . Rewrote channel update to make data 0 act as sample terminator. Note: In all currently supported GA20 sample ROMs, samples are followed by 1 to 16 bytes with value 00 (depends on alignment). Thus I assume that this is a sample end marker. The "sample end" register might be used for something else (looping?).
  . Assumed keyon is at reg 6 bit 1 (not just any non-0 value), removed 2nd end of sample check, misc refactor and added notes.
