- New Cheat.dat: http://www.mamecheat.co.uk/
- Hitachi H8 CPUs: Added H8/3003 support
- Hudson Soft HuC6280 CPU: Internalized peripherals and sound
- Intel I386 CPU
  . Fixed a bug that could cause a relatively common CPU detection check to see a 386 as a 486. Fixed a dead code bug.
  . Added enumeration for feature information bits
  . The CPUID opcode logs an error message if called with a not yet supported value in the EAX register 
  . Added Athlon XP processor
- Intel I486 CPU: XADD instructions must set flags based on sum result (i386\i486ops.hxx). This is required by Windows XP setup.
- Intel i860XR: Hotfix for coverity issue (cpu\i860\i860dec.hxx)
- MC6809 CPU: Disassembly tweaks: Use FCB directive to represent illegal opcodes. Removed unnecessary spaces for instructions without operands (m6809\6x09dasm.cpp).
- MOS Technology M6502 CPU: Added MCU capabilities
- NEC V33/V53 CPUs
  . Emulated V33/V53 expanded addressing mode, including BRKXA and RETXA instructions.
  . Start pushing down V33/V53-specific memory stuff into a new base class
  . Added 8-bit mappings to V53 for internal peripherals and save associated registers
- PSX CPU: Hookup debugger_exception_hook and debugger_interrupt_hook
- Texas Instruments TMS57002 CPU
  . Added instructions 3c/3d, make them behave as NOP as they're undocumented and not understood. Added undocumented instruction saom / raom, they set saturation mode for the ALU. Added a few unimplemented instructions.
  . Fixes to make Taito Zoom DSP working. Implemented MACC pipeline. Added callbacks for dready, EMPTY and PC0 pins.
  . Proper behavior of CMEM UPLOAD mode. Fixed an issue where program is not properly loaded if PLOAD is set after a program has already been written.
  . Fixed a TMS57002/KonamiGX regression. Changed flag instructions back to type "2b" (cpu\tms57002\tmsinstr.lst).
  . Added trick to reduce the compiler memory usage
- Toshiba TMP87PH40AN CPU
  . Flesh out TLCS870 core. This added opcode execution for all TLCS870 opcodes that I previously wrote a skeleton of for the Hyper Neogeo 64 IO MCU, refactoring and cleaning code along the way. Flags still need verifying (and in some cases adding), CPU cycles for timing still need adding. TMP87PH40 specific peripherals (including interrupt handling) etc. still need adding. Overall this should move things forward and make it easier to work with tho, obviously with the goal of finishing it off and seeing if the dumped HNG64 IO MCU is suitable for all board types or not. ALU flags, passes internal RAM check. Interrupt wait loop depends on JF always getting set.
  . Takes first interrupt. Bit of port interface guessing to pass port based shared RAM check. Added analog ports, fixed some TLCS870 exec issues. Start adding stubs for various tlcs870 features. Fake timer to push it along.
- Zilog Z180 CPU: Added workaround for missing serial and counter emulation (CSIO flags and FRC). This is necessary for Lucky Ball 96.
- Discrete sound
  . Fixed DISC_555_TRIGGER_DISCHARGES_CAP option in DISCRETE_555_MSTABLE. This fixes the sound in Amazing Maze so that it plays for more then 30s (sound\disc_dev.hxx).
  . Fixed filenames in DISCRETE_CSVLOGx and DISCRETE_WAVLOGx making them function again and use device->basetag() (sound\disc_sys.hxx).
- Hudson Soft HuC6280 sound: Added notes
- NEC uPD7759 sound
  . Converted to use device_rom_interface and added md input for selecting between master and slave
  . Finished hooking the UPD7759 up to the following drivers VGM player, Bay Route (encrypted, protected bootleg), E-Swat - Cyber Police (bootleg, set 1), Golden Axe (encrypted bootleg) and Passing Shot (2 Players) (bootleg)
- QSound (HLE)
  . Fixed a couple of typos pointed out by Coverity (dsp16\dsp16fe.cpp)
  . Saturate ROM offsets (sound\qsoundhle.cpp). Apply ADPCM sample bank (sound\qsound.cpp).
  . Added improved qsound_hle core. Use ROM lookups instead of copying tables at init and use enums for most DSP ROM addresses. Replacing memset at the cost of legibility (sound\qsoundhle.cpp).
- Seta X1-010: Simpler handlers
- Sound stream: Fixed sound_stream::sample_rate(). Was broken since adding support for setting a zero rate, nothing appears to rely on it (emu\sound.h).
- Yamaha AICA sound
  . Added input clock related to sample rate
  . Implemented MONO/MVOL and EXTS mixing
- Yamaha YMF278B sound: Added device_post_load for FM part and device_clock_changed
- YMF292-F SCSP: Added device_clock_changed, support device_rom_interface, use correct clock frequency, "space" removal and fixed some endian issues.
- Cassette tape image: Allow cassette sound to be directly routed to a sound output (imagedev\cassette.cpp)
- Discrete Netlist: Added netlist for a large portion of Atari Gran Trak 10 schematics (1974) - still not working
- Floppy
  . Added debug asserts to help catch geometry errors (formats\flopimg.h)
  . Fixed FIFO mess-up on unexpected FIFO pushes on HX5102 floppy drive (machine\upd765.cpp)
  . Simplified API of machine\wd_fdc.cpp
- Imgtool
  . Fixed parsing options with enum values. When parsing an enumerated option, we should use the parameter of the enumerated value, as an integer, instead of the raw identifier as a string. The behaviour probably changed around commit b60879e595 (2016-08-27), but modules still expect the old behaviour.
  . Fixed off by one error with leap years (util\timeconv.h)
- Intel 8155 RIOT: Eliminated unnecessary memory interface for internal RAM
- Intel 8255 PPI
  . Added handlers for strobed Port A/B reads in Modes 1 & 2, this allow some side effects to be disabled in Sindbad Mystery and Super Locomotive.
  . Refactor to make clear the exact sequences of actions acka_r and ackb_r correspond to
- MB8421 SRAM: Converted callbacks to DEVCB3 and update to recent coding standards
- MC146818 RTC: Fixed problems with direct-access mode
- MC68681 DUART: Added Exar XR68C681 support to MC68681 with MISR register and extended baud rate
- Polygon rendering: Bumped up the default number of scanlines per bucket (video\poly.h)
- PowerVR 2: Turn some per-pixel branches into per-polygon branches. Note: In MAME 0.200 I did something stupid from a performance standpoint, which was to select the shading function on a per-pixel basis even though it can only change on a per-polygon basis. This commit uses c++ templates and inline functions to so that the compiler's constant folding can eliminate the switch statement that selects shading functions (thus making the choice a per-polygon one). I also did the same thing for the texture and bilinear filtering checks. This brings back a little less than half of the performance hit on my PC, so things still aren't as fast as they used to be. Benchmark (running a full cycle of Crazy Taxi NAOMI's attract) on my PC: Before MAME 0.200: 30%, after MAME 0.200: 23% and with this commit: 26%. Regarding the other 4% of the drop, that is coming from the pixel shading. When I hardcode powervr2 to always use shading instruction 0, performance jumps up to 29.5%, but when I hardcode it to use shading instruction 3 performance falls a bit down to 25%. Shading instruction 3 is the most complicated of the four and shading instruction 0 is the simplest, so I think that proves that the shading instructions themselves are a major bottleneck. I don't have any ideas about how to make them faster yet.
- PSX GPU: Use device_palette_interface. Real hardware is connected with triple 8-bit video DAC; so allow RGB24 display. Some old GPU has only 16bit video output. Fixed debug mesh display.
- Sega 315-5124: Fixed off-by-one bug in 315-5124/315-5313 sprite zoom limit. Fixed 315-5214 tile/line numbers in leftmost column. Avoid flagging sprite collisions twice on the same line for 315-5313. Make code more consistent.
- Timekeeper
  . Default input clock for all devices
  . Converted M48T37 callbacks to DEVCB3 (atlantis.cpp and vegas.cpp)
- TMS9928A VDP: Configuration modernization: Replaced callback configuration macros with DEVCB3 (slightly shortening function names in the process). Changed configured clock to be twice the dot clock (as on hardware), rather than equal to it. Allow the VDP to configure the screen in device_config_complete (taking into account 60 Hz/50 Hz variations), making MCFG_TMS9928A_SCREEN_ADD_NTSC/_PAL macros obsolete. Added notes on clock outputs. Fixed number of vertical lines for NTSC devices. Eliminated the clock validity check, which has fulfilled its purpose.
- Z80 SCC Channel
  . Serial control signal fixes: /CTS, /DCD and /SYNC are active low lines represented as 1's in rr0 when asserted. Immediately deassert /RTS in some circumstances. Fixed rr1 "all sent" status handling. There is no ring indicator input line. Generated interrupts for /SYNC input. Fixed Z-BUS access.
  . Updated /WREQ when transmitter is enabled/disabled, use 0 for assert state of active low output.
- Z80 SIO: Ignore "Send Abort" command when not in SDLC mode - allows (MESS) jade.cpp to start.
- actfancr.cpp and dec0.cpp: Reduced code duplication
- cntsteer.cpp: Eliminated MCFG_DEVICE_VBLANK_INT
- cvs.cpp: Replaced ROM patches with protection simulation for Hero, Hunchback Olympic and Superbike
- dcheese.cpp: Corrected palette size. Reduced some runtime tag lookups. Cleanup naming etc.
- deco32.cpp: Fixed background color for Dragon Gun. Added notes to video\deco_zoomspr.cpp.
- hikaru.cpp
  . Fixed AICA sound output and added XTAL connected with AICA. Correct number of AICAs (1x at motherboard and 1x at AICA PCB).
  . Dumped Development / prototype BIOS v.074
- hng64.cpp
  . Flesh out TLCS870 core. Added notes about MIPS side IRQ, sams64 IRQ and some IRQ addresses.
  . Added DPRAM device. Added dualport ram device (really just gets treated as RAM, but on a technical level, it should be a device). Converted fake IO handlers to 8-bit, and ports to 8-bit since the real IOMCU reads 8-bit ports, the DPRAM is also 8-bit, and this should make transition to proper emulation easier later. Hook TLCS870 up to the dualport RAM device. Allow emulated TLCS870 to do the initial handshake with the MIPS instead of the simulation (takes a few seconds before ffwa allows coins now, but thats probably due to IRQ timing and timers being completely fake). Read a bunch of ports through the IO MCU instead of simulation. Start actually reading some inputs through IO MCU.
  . Allow IOMCU to trigger MIPS IRQs. Removed coinage hack in Buriki One. 
  . Added save states to sound\l7a1045_l6028_dsp_a.cpp
  . Misc cleanups. Added kludge so that Roads Edge and Xtreme Rally can be coined up and played without them crashing. Properly mapped inputs.
  . Documented outputs (lamps, coin counters) and use device finder for analog ports
  . Improved sprite filtering in Roads Edge
- konamigx.cpp
  . Fixed a TMS57002/KonamiGX regression. Changed flag instructions back to type "2b" (cpu\tms57002\tmsinstr.lst).
  . Hook up channels 3 and 4 of TMS57002. The Lethal Enforcers II schematics are not complete so I couldn't figure out exactly how they are connected to the sound chips and the DAC, but this sounds OK for now. Documented TMS57002 outputs.
- konamim2.cpp and vegas.cpp: Tidy-up terminal
- laserbat.cpp: Added PLS100 (82S100) PLA device
- m72.cpp: Overhaul V30/8751 comms using DPRAM and GENERIC_LATCH_8
- mainevt.cpp: Added proper screen parameters and some extra notes
- mastboyo.cpp: Cleaned-up the driver. Added remaining dipswitches allowing the initial test mode.
- naomi.cpp
  . Added NAOMI Development / tester BIOS (Nov 1998), Ferrari F355 DLX prototype Japan and Export BIOSes, NAOMI Rev F Export BIOS and Ferrari F355 DLX prototype motor board firmware.
  . Dumped  Cycraft Motion PC software for Club-Kart and Initial D Arcade Stage Ver. 3 Cycraft Edition
- neogeo.cpp: Added start buttons to dial controller (bus\neogeo_ctrl\dial.cpp). This fixed start buttons don't work in Pop 'n Bounce (ID 07073)
- policetr.cpp
  . Cleanup. Converted bitmap_ind8 for dstbitma. Cleanup pointer/runtime tag lookups/ACCESSING_BITs/naming. Added save states.
  . Removed a no-longer-needed video check. Identified some unknowns ports.
- seta.cpp
  . Converted X1-010 address XOR into LRW8. Simpler handlers for X1-010 sound.
  . Added NVRAM and PCM mute control to Caliber 50
  . Fixed Twin Eagle music (timing is related to screen framerate) (ID 00867)
- seta.cpp and seta2.cpp: Added memory_banks for X1-010 bankswitching.
- taitogn.cpp and zn.cpp
  . ZOOM ZSG-2 (sound\zsg2.cpp)
    . Improved Taito Zoom ZSG-2 sound emulation. Implemented emphasis filter, this is a noise reduction scheme that amplifies higher frequncies to reduce quantization noise.
    . Added sample interpolation and another adjustable lowpass filter. This seems to be roughly what real hardware does.
    . Improved panning registers and identify DSP output gain registers. Register 0b appears to be status flags. Proper ramping implemenation and added register map.
    . Attempt to reduced clicks
    . Made the emphasis filter much more simple. I think this matches hardware, as a filter like this could be implemented with very few gates in hardware. Also reset the filter state when the sample position reaches the start address, this fixes Ray Crisis song #9.
    . Clamp audio output to 16-bits. Optimized the filters. Saturated the emphasis filter output. Right shifting will cause unwanted noise.
    . Discharge the output filter slowly when the cutoff is set to 0. Fixes popping noises in Ray Crisis song #12.
  . Taito Zoom ZSG-2 sound board (audio\taito_zm.cpp): 
    . Added working DSP emulation. Reduced MCFGs. Added device_mixer_interface for sound gain. Added imperfect_features related to DSP and notes. Fixed TMS57002 clock.
    . Adjust volume balance, hopefully fixing Psyvariar -Revision-. I would need hardware recording for proper verification though.
  . Texas Instruments TMS57002 CPU
    . Added instructions 3c/3d, make them behave as NOP as they're undocumented and not understood. Added undocumented instruction saom / raom, they set saturation mode for the ALU. Added a few unimplemented instructions.
    . Fixes to make Taito Zoom DSP working. Implemented MACC pipeline. Added callbacks for dready, EMPTY and PC0 pins.
    . Proper behavior of CMEM UPLOAD mode. Fixed an issue where program is not properly loaded if PLOAD is set after a program has already been written.
- tx1.cpp
  . Fixed non-functioning shifter in Buggy Boy and Buggy Boy Junior (layout\buggyboy.lay and buggybjr.lay) (ID 07058)
  . Fixed missing engine sounds in Buggy Boy and TX-1 (ID 07059)
- yunsung8.cpp: Minor doc update
- Astro Wars: Mark rom astro.13i as bad dump, because game resets at start of stage 5. Suspected bad byte at 0x2a00.
- Battle Rangers: Removed unnecessary handlers, bank read/writes and added notes.
- Canvas Croquis: Fixed flip screen
- Centipede / Millipede / Missile Command / Let's Go Bowling: Misc improvements: Better flash mapping means the IRQ handler can run now without crashing. Hooked up up/down and service2 (0) keys to navigate service mode. Bankdev added to handle 2000-AFFF region. NVRAM access to the 29c020 flash ROM now works properly.
- City Connection: Added PROMs and PLDs to clone City Connection (set 2)
- Come On Baby: Fixed CPU model so that it doesn't jump to 0 when it writes to a p6+ msr
- Decathlete: Implemented 315-5838 compression / encryption chip
- Dynamite Dux: Added PROMs and PLDs to clone Dynamite Dux (Datsu bootleg)
- El Fin Del Tiempo: Various things: Use line callback instead of VBLANK_INT and acknowledge interrupt. Use (likely) addressable latches instead of pointers to (fake?) RAM. Added watchdog timer. Clean up audio CPU ROM region length.

- F1 Exhaust Note: Mapped second start button
- Funky Ball: Use UART and RS232 port for diagnostic serial output
- Gondomania: Decapped MCU for clone Makyou Senshi (Japan)
- Mega Phoenix: Verified PALs as BAD_DUMP/protected
- Operation Wolf
  . Added C-Chip ROM, credit to Caps0ff for dumping it. Old C-Chip simulation is retained for documentation purposes. Added accurate hardware information for documentation.
  . Actually properly disable Operation Wolf protection simulation, fixed coin counters.
- PinMAME
  . Various mrgame.cpp updates and modernizations. Screen raw parameters (circuitry is surprisingly similar to Galaxian). Addressable latch for video CPU. VBLANK callback instead of MCFG_DEVICE_VBLANK_INT (interrupt also acknowledged now). Separated machine configuration for World Cup 90, which now displays something.
  . Use 'Generic ripple counter' device in play_2.cpp
- Psychic Force: Added a new e22-11.2 rom to clone Psychic Force EX (Ver 2.0J) (Game now playable)
- Spectar: Fixed explosion samples playing (audio\targ.cpp) (ID 07067) (ID 07068)

- MAME
  . VIDEO RENDERING SYSTEM
    . Better support for screen orientation/geometry
      . Eliminates the need for the horizontal/vertical/LCD/SVG layout files
      . Screens can now have orientation and physical aspect ratio specified
      . RASTER/VECTOR defaults to 4:3, LCD/SVG defaults to square pixels at config time
      . System orientation is applied on top of screen orientation
      . Added save state support for std::array/C array nested to any depth
      . Automatically generated single-screen views and orientation flags in XML output now work correctly for systems with multiple screens in different geometries/orientations, e.g. housemnq, rocnms, stepstag or netmerc.
      . The "core rotation options" only interact with system orientation. Allowing multi-screen systems to work well with one monitor per emulated screen is a complex topic. System orientation also affects the GFX viewer while screen orientation doesn't. The orientation displayed in the system selection menu is from the system orientation.
      . Make rectangle work better with constexpr, changed many things to use designated getters/setters.
      . Ignore SVG dimensions (emu\screen.cpp)
      . Clean up some corner cases in layouts with repeating blocks. Make complay.py validate many more elements and attributes. Make complay.py easier to use for just validating a layout. Removed redundant view from Sega VMU layout. Make buttons visually respond to input in (MESS) whousetc.lay. Added view with LED displays as well as terminal for (MESS) aim65_40 and use repeats. Start documenting layout format. Make highlights visible on white squares in (MESS) mephisto_modena.lay.
      . Allow  and  to work on group references. Fix some corner cases where group bounds could be miscalculated and MAME could incorrectly refuse to instantiate groups.
    . Calculated physical aspect ratio whenever required, not in device_config_complete, since the renderer caches the result anyway (emu\screen.cpp).
    . Fixed have_screen_update(), which was broken and returned false under any valid configuration, and rename the function has_screen_update(). This fixes regressions in 'Granny and the Gators' and other drivers using custom update functions with CDP1861, CDP1864 and TMS992x VDPs (emu\screen.h).
    . BGFX: Improved rendering with artwork by 5-10x or more
  . DEVICE
    . Removed timer_set() in orbit.cpp, seta.cpp, machine\namco50.cpp and namco53.cpp
    . Use already present device_finder (machine\pcecommn.cpp)
    . Removed some device tag look-ups from model3.cpp and machine\inder_vid.cpp
    . Added device_clock_changed to sound\k053260.cpp, k054539.cpp, qsound.cpp, sn76496.cpp, ymf262.cpp and ymf278b.cpp
    . HuC6272 device_add_mconfig modernization
    . Added DEVCB3 support to MC6854, ataintf, MB89352 and WD33c93
    . Set default clocks to 0 in machine\8042kbdc.h, i8255.h, idectrl.cpp, intelfsh.h, mb89352.h, ram.h, wd33c93.h and sound\volt_reg.h
    . Removed legacy DEVCB accessors in 8042kbdc, MB89352 and MC6854
    . Allow set_tag() with a reference or a pointer to a device (emu\devfind.h). Fixed the build by removing calls that don't exist when DeviceClass happens to be an interface (emu\devfind.h).
    . Removed MCFG usage in machine\6522via.h, 6532riot.h, 6821pia.h, 68230pit.h, 68307.h, 6840ptm.h, 6850acia.h, 7200fifo.h, 7400.cpp, 7404.cpp, 74123.h, 74145.cpp, 74148.cpp, 74148.h, 74153.h, 74157.h, 74161.h, 74165.h, 74166.h, 74175.h, 74259.h, 74259.h, 8364_paula.h, aakart.h, adc0808.h, adc083x.h, adc0844.h, adc1038.cpp, adc1213x.h, akiko.h, am2847.h, am53cf96.h, am9519.h, amigafdc.h, ataintf.cpp, bankdev.h, cxd1095.h, eeprom.cpp, idectrl.cpp, i8155.h, mos6551.h, nvram.h, pci-ide.cpp, ram.h, z80sio.cpp and cpu\cosmac\cosmac.h	
    . Machine config modernization for cops, gameplan, gts3, gts3a, itech32, itech8 and jvh
    . Converted 'Generic ripple counter', MB8421, MC68901 and M48T37 to DEVCB3. Added DEVCB3 accessors to I8279, YM2608, ES5503, TMS34061 and Z80 SCC
    . Modern configuration accessors for COP400, NVRAM, TLC34076 and Watchdog
    . Fetch screen to be potentially configured during device_config_complete. Allow device finder to be used as an argument for set_screen (emu\divideo.cpp).
  . MEMORY SYSTEM
    . Allow simplified versions of handlers
      . A standard memory handler has as a prototype (where uX = u8, u16, u32 or u64): uX device::read(address_space &space, offs_t offset, uX mem_mask) and void device::write(address_space &space, offs_t offset, uX data, uX mem_mask). We now allow simplified versions which are: uX device::read(offs_t offset, uX mem_mask), void device::write(offs_t offset, uX data, uX mem_mask), uX device::read(offs_t offset), void device::write(offs_t offset, uX data), uX device::read() and void device::write(uX data). Use them at will. Also consider (DECLARE_)(READ|WRITE)(8|16|32|64)_MEMBER on the way out, use the explicit prototypes. Same for lambdas in the memory map, the parameters are now optional following the same combinations.
      . Examples: bloodbro.cpp, cabal.cpp, dcon.cpp, legionna.cpp, pntnpuzl.cpp, r2dx_v33.cpp, raiden2.cpp, machine\6522via.cpp and audio\seibu.cpp
    . Put capabilities at parity (emu\addrmap.cpp, devcb.cpp and emumem.cpp)
    . Default input clock for 'Address Map Bank' (machine\bankdev.h)
  . UI
    . Make the software list "special" to prevent pausing while typing (ui\imgcntrl.cpp)
    . Clean up some outdated "game" terminology in clifront.cpp
    . Fixed incorrect "On/Off" color on "AutoFire Status" screen (ui\cheatopt.cpp) (ID 07069)
  . Fixed disk entry processing (emu\romload.cpp)
  . Optimised start up by delaying the state save sort and check for duplicates until all the devices have been started. This has the most visible effect on vgmplay because it registers over thirty thousand state save entries.
  . Adjusted indentation of DTD to better reflect structure (mame\info.cpp)
  . Multi-Language: Created a full Norwegian translation
- SDLMAME: Fixed debug assert failure when using SDL fullscreen toggle
- VGM player
  . Added support for C140, OKIM6258, SCSP, X1-010, Y8950, YMF262 and YMF278B. Preliminary hook up of YM2610. Added QUICKLOAD and software list support. Start all clocks at zero and reset all sound chips on a song change. Note: This is damn sensitive code (emu\schedule.cpp and sound.cpp), and generates differences all over the place we don't really explain. The changes should be justified by themselves and tested in collaboration with Tafoid to ensure the differences are not a problem. Don't try to update m_totalcycles on devices with a zero clock, as it will crash (emu\schedule.cpp).
  . All header sizes are valid for all versions from 1.50 on, as long as header has at least 64 bytes. If the VGM data starts at an offset that is lower than 0x100, all overlapping header bytes have to be handled as they were zero. Fixed OKI 6295 clock. Fixed VGM player don't crash on YM3438 songs. Updated warning checks.
  . Skip writes for data that hasn't been loaded, fixes crash in Wally wo Sagase. Trigger the clock hacks on specific values, to avoid causing problems with correct files.
  . Added all sound chips (including multiple instances supported by the vgm format) & all chips have been reordered into the vgm chip id order. ES5503/SAA1099/VSU now work but the other new additions are greyed out (these will require work to the sound cores themselves).
  . WonderSwan sound is working now. Sound is muted when songs end
  . Updated hash\vgmplay.xml to include all major packages makers (VGMRips, SMSPower and Project2612), now consisting of over 3100 game entries. Great effort has been made to keep package shortnames consistent to their source origin (arcade or machine softlist). All information in the individual package's readme files were carried over into the hash file. Further refinement will be done later to fill in missing dates, publishers, and other information. While there are still some sound chips not handled by vgmplay, the vast majority of these will have accurate playback.
- Compiling
  . Fixed Arcade build
  . Extended the existing TUN/TAP OSD module (modules\netdev\taptun.cpp) to support Windows through the TAP-Windows6 driver (https://github.com/OpenVPN/tap-windows6)
  . Fixed for undefined fmin & ceil on GNU Guix with GCC 5.5.0 (cpu\mips\mips3.cpp and ps2vif1.cpp)
  . Added DEVCB workround to allow Mitsumi keyboard to build with Visual Studio (src\emu\devcb.h)
- Debugger
  . Use std::deque for token stack (debug\express.cpp)
  . Moved scripting functions down into console (debug\debugcpu.cpp)
  . Mask address expressions in debug disasm view (debug\dvdisasm.cpp)
  . Mask address expressions correctly in debug memory view when using physical addresses beyond logical limits (debug\dvmemory.cpp)
  . Don't apply logical address masks to physical addresses in debug memory accesses (debug\debugcpu.cpp)
  . Fixed scrolling glitch in memory view when address expression is applied (debug\dvmemory.cpp)
  . Apply logical address mask properly in debug disassembly view. Associated core changes: Moved definition of address_space_config from dimemory.cpp to emumem.cpp (declaration was already in emumem.h). Added getters for more members of address_space_config with future privatization in mind.
