- CPU
  . ADChips SE3208: Clean up disassembler and remove unwanted newline
  . Fujitsu MB9061x: Implemented timers 0 and 1, including external event counter mode
  . Fujitsu Micro F2MC-16
    . More opcodes and more robust IRQ handling. Fixed BBC branch offset, add savestates, cleanup variable usage in utility functions.
    . Added more opcodes to diassembler (f2mc16\f2mc16dasm.cpp) and normalized bit syntax. This allows disassembling most of the Namco System 23 "Extra I/O" programs, which use an MB90611A.
  . Hitachi H8: Disassembly improvements: Correct sign extension for 16-bit absolute addresses. Use H' prefix for hexadecimal numbers. Restrict address length depending on model. Format arguments in separate column.
  . Hudson Soft HuC6280 PSG: Added workaround to HuC6280 core to fixed music speed in Crude Buster, Dark Seal and Vapor Trail. Use official names for banking registers. Reduced logical width of address space. Fixes the tempo of Crude Buster music played by one of the OKI6295's speeds up when the flamethrower is used (ID 00389). Fixes Dark Seal when using your weapon the music playback would ever so slightly increase (ID 00130). Fixes Vapor Trail sound driver messed up during game play, tempo all wrong when firing (ID 02108).
  . MIPS-I: Added undocumented behaviour of REGIMM opcode
  . Mitsubishi M37710S4: Internalized timing for A-D converter
  . MOS Technology M6502
    . Fixed reset procedure. Fixes incorrect default stack pointer position for the M6507 CPU in (MESS) Atari 2600 (ID 06486). The console hardware uses $FD. MAME reveals the default stack to be set to $BD.
    . Added dummy reads before reset (cpu\m6502\om6502.lst)
  . MOS Technology M65C02: Added stack access to 65c02 reset too (cpu\m6502\om65c02.lst)
  . Motorola MC68HC05L9: Added (somewhat provisional) model-specific register names
  . Philips SCC68070: Split up internal register block handlers. Added some RESET behavior.
  . Texas Instruments TMS34020: Fixed BLMOVE aligment handling. BLMOVE has actually 4 different cases of execution based on two lowest bits in opcode, which were not properly handled. Fixes endless loop in atronic / atricmon.
- SOUND
  . AY-3-8910A PSG
    . Added feature value for chip specific features. Added runtime pin26 handler. Use struct for tone and envelope. Reduced performance issue. Reduced defines and unnecessary lines. Fixed naming and spacings. Added notes.
    . Don't play fast and loose with register initialization; some builds warn about that.
  . AY8930 EPSG: Implemented expanded mode
  . K051649 SCC1: Fixed mirroring in address map. Added save states. Fixed spacing. Reduced unnecessary lines. Use shorter/correct type values.
  . Namco C140: Added timing output to trigger periodic FIRQ

- DEVICE
  . Discrete Netlist
    . Added simple oscillator with 74LS14 and voltage and current source test
    . Removed a lot of C library use and instead use C++. Improved pstring compatibility to std::string. Prepare removal of pstream.
    . Prepare move to C++ streams and later std::string. Fixed more lint and clang pedantic warnings/errors. Fixed some bugs.
  . DP8350 CRTC: Apply some subtle timing fixes and save one more variable
  . DS1994: Added FIXME comments. Removed redundant tag from logging helper. Corrected device name. Removed copy/pasted application note (copyright infringement).
  . Hitachi HD44780 A00 LCD Controller: Added alternate interface using direct writes to bus control lines. This is necessitated by an odd edge case where the LCD controller is addressed in 4-bit mode and the busy flag is polled continuously by setting R/W = 1, RS = 0 and E = 0 and then just waiting for DB7 to be cleared. In this case, the ordinary read operation will select an alternate nibble each time, resulting in spurious values. Hitachi's HD44780 datasheet does not actually recommend this polling method, so it might actually be for one of the many compatible LCD controllers from other manufacturers.
  . Hitachi HD6845S CRTC: Specialized the cursor emulation. For the HD6845 the cursor does not wrap around as it does for the MC6845.
  . Hitachi SH-2: Added SH2 clock multiplier logs
  . Imagetek I4100 052 VDP: Reduced duplicates. Use struct for sprite drawing routines. Fixed spacings. Use shorter/correct type values. Added notes.

  . Intel 8253 PIT: Minor refactor
  . K051960 Sprite Generator: Use device_video_interface to hook screen
  . K052109 Tilemap Generator: Use callback to generate IRQ for most drivers. Fixed IRQ enable logic (otherwise simpsons is very broken). Use device_video_interface to hook screen.
  . MagicEyes VRender0 Video Engine: Various improvements over Vrender0 based systems: Made some experimental work with menghong based HW, allowing 'Crazy Dou Di Zhu II' to boot and improving menghong colors. Internalized video and audio components inside the SoC. Wrote a preliminary UART subdevice. Made external video clock to be settable by the host driver.
  . Motorola MC6845 CRTC
    . Improved the cursor emulation. Implemented partial cursors.
    . The MC6845 shows a full cursor if the cursor end raster address is greater than the maximum raster address, restore that case in general. The issue on the BBC, that uses the HD6845S, might be the use of the maximum raster address here, it appears to be programmed differently on the HD6845S and also to depend on the interlaced mode. This patch fixes the BBC while preserving the cursor emulation for the MC6845.
    . Added address cursor display edge case in interlaced mode. It appears that the cursor is not displayed when the start raster address is equal to the maximum raster address in the 'interlace and video' mode. At least this addresses a claimed regression in the (MESS) apricot machine. To be explore further on hardware. The maximum raster address was also off by one in these calculations.
  . Sega 315-5124 SMS1 VDP: Fixed naming
  . Sega 315-5313 Megadrive VDP: Fixed 3bit color mode masking. Added gfx/palette viewer for debug (off for default). Simpler VRAM write/replace function. Converted drawing routine using device_gfx_interface. Added device_gfx_interface for gfxdecode. Added gfx for shadow/hilight case. Fixed naming.
- CHDMAN: Clean up some archaic string code

  . Added preliminary RTFM joystick and serial joystick support (machine\archimds.cpp). Added compatibility tests.
  . Rewrote Acorn VIDC10 into own device file. Improved raster effects on games that dynamically change palette on active frame. Added stereo sound support. Internalized palette and externalized screen. Fixed off by 16 sound DMA transfers, improving sound quality.
  . Generate u255 law sound table on device start (machine\acorn_vidc.cpp)
- champbas.cpp and lwings.cpp: VBLANK IRQ modernization
- cps3.cpp
  . Hook coin locks and counters
  . Return 5 and 6 buttons to JoJo's Venture and clones (they used in dev.mode). Fixed intro missing star sprite and game title bg color.
  . Changed 'SS' RAM and registers to 8bit. Renames of function's/variable's names to their actual functions. Misc cleanups. Documentation update and fixes.
  . Delay Palette/Character DMAs interrupt, get rid of periodic irq and more register docs.
  . More docs and cleanup

- nmk16.cpp: Added on-board chip & XTAL verifications
- nss.cpp, sfcbox.cpp and snesb.cpp
  . Do not update HDMA if enabled channels are the same (machine\snes.cpp). Fixing (MESS) Pilotwings (ID 06205).
  . Fixed 5a22 and spc700 clock cycles (cpu\g65816\g65816.cpp and cpu\spc700\spc700.cpp). Fixes (MESS) snes jdredd stops working after title screen (ID 06901) and snes firemenu has black screen (ID 07419).

- vastar.cpp and zodiack.cpp: Implemented device_video_interface (video\orca40c.cpp)
- Air Buster, DJ Boy and Heavy Unit: Generate sound IRQ from YM2203 rather than VBLANK

- Chelnov
  . Hook up MCU to clone Chelnov - Atomic Runner (Japan, bootleg with I8031, set 1)
  . Redumped and corrected clone Chelnov - Atomic Runner (Japan) color BPROMs
- China Gate: Added PCB layout for the main, second board and information on TRJ-100. This patch update China Gate to have more concrete information on TRJ-100. Now pin assignments are almost investigated as we cantry dumping it. Also, this comment clarify which SRAM chip constructs bgvideoram.
- Commando: Accuracy improvement. Note: The main CPU frequency is 3 MHz, after a two-stage FF clock divider. The CPU clock is gated by bus arbitrion logic. The CPU clock is halted until video hardware has an opening in memory access, then the CPU is allowed to access common memory. This slows down the CPU but doesn't alter its basic 3MHz frequency. There is also a DMA circuit that copies object data from the CPU RAM to a buffer this also slows down the CPU as it is halted during that time.
- Cross Puzzle: Improved flash loading. RTC interface improved but still nonfunctional.
- Cruis'n USA: Redumped PAL a-19993.u38
- Ghosts'n Goblins: Removed watchdog. Note: There is no watchdog in GnG, as previously stated in the MAME driver. Instead, there is a DMA circuit that copies object data from the CPU RAM to a buffer this also slows down the CPU as it is halted during that time. The DMA is triggered when a certain memory location is addressed. That location was thought to be a watchdog before.
- Heavy Unit: Use correct graphics rom for clone Heavy Unit (Japan, Newer). 
- Hyper Duel: Added MACHINE_NO_COCKTAIL flag related to wrong flipped screen displaying
- Major Havoc: Fix for Alpha One clones which doesn't have coin and service ports
- Rock 'n' Roll: Added EEPROM dump
- Sprint 4: Added fix for Player 4 default controls
- Street Fighter II': Champion Edition: Added a PAL dump and some repair info to clones (Mstreet-6, bootleg, set 1), (Mstreet-6, bootleg, set 2) and (Mstreet-6, bootleg, set 3)
- Tournament Table: Use device_palette_interface, save bitmaps and converted update method to RGB32.

- Renamed (birdtry) to (birdtrya), (powerinsp) to (powerinspu) and (psyvaria) to (psyvarij)
- MAME
  . VIDEO RENDERING SYSTEM
    . Print a warning and continue on encountering malformed XML in a layout file (emu\render.cpp)
    . Added 2x2 grouped case of 16x16 gfx layouts. These are made of 4 8x8 tiles, currently 4bpp packed and 8bpp raw layout is exists. More usage of generic gfx layouts. Fix naming and spacing (video\generic.cpp).
    . Eliminated extract_scanline8/16/32, replacing the scant existing usage with std::copy_n (emu/drawgfx.cpp).
    . Make bitmap8_t, bitmap16_t, bitmap32_t and bitmap64_t specializations of one class template (util\bitmap.cpp).
    . Renamed emu\drawgfxm.h to drawgfxt.ipp and replaced the mega-macros with template functions
    . Mark drawgfx core templates inline to prevent linker trying to coalesce them across compilation units, and hopefully encourage the compiler to specialise them when drivers call them with fixed argument values. Make wraparound parameter for ROZ drawing functions bool - it's a simple true/false value. Clean up spacing in a few places.
    . Don't force throttling while paused (emu\video.cpp)
    . Added assert to catch wrong pixclock configuration (emu\screen.h)
    . Improved contains assert in emu\tilemap.cpp, fixing tilemap viewer in debug build.
  . LUA engine
    . Exposing running_machine::exit_pending() and running_machine::hard_reset_pending() to LUA.
    . Fixed issue that caused most LUA callbacks to be duplicated (mame\luaengine.cpp). Fixes "autofire" plugin is not working properly (ID 07408).
  . UI
    . Distinguish DIP switches that belong to different devices but have the same name in UI menu. This is most likely to occur when multiple instances of the same device type are configured on bus slots (ui\inputmap.cpp).
    . Fixed presentation of error message about invalid INI options (mame\mameopts.cpp)
  . PLUGINS: Added time functions to cheat sandbox (plugins\cheat\init.lua)
  . Changing some arrays to use std::array<> in natkeyboardemu/natkeyboard.cpp	
  . PORT_CUSTOM simplification:
    . Removed both arguments from CUSTOM_INPUT_MEMBER (adding template parameters as necessary)
    . Removed 'param' from PORT_CUSTOM_MEMBER and assume 'device' is DEVICE_SELF (use PORT_CUSTOM_DEVICE_MEMBER if it isn't)
    . Replaced PORT_CUSTOM_MEMBER with PORT_READ_LINE_MEMBER where applicable
    . Added implicit DEVICE_SELF variants of PORT_READ_LINE_DEVICE_MEMBER and PORT_WRITE_LINE_DEVICE_MEMBER
    . Removed ioport_field argument from PORT_CROSSHAIR_MAPPER
    . Separated captflag and gmgalax driver classes from base
- SDLMAME
  . The current Emscripten release is not happy with the use of '-s ERROR_ON_MISSING_LIBRARIES=0' as a link option, it gives an error stating that all libraries must now be present, so remove that use. This leaves a missing 'util' library. This did not appear to be needed on the few builds I have tried, and this patch avoids adding this library for asmjs (osd/sdl.lua; configuration=asmjs).
  . Avoid explicitly linking SDL2_ttf. It appears that it is sufficient to include '-s USE_SDL_TTF=2', and emcc links in the SDL2_tff library, and it does not like attempts to link this twice (osd/sdl.lua; configuration=asmjs).
- MAC OS X
  . Fixed exception on MacOSX (netlist\plib\pfmtlog.cpp). Some unknown system library seems to force the use of the global locale on OSX. This is not the case for other *nix or Windows builds. This commit fixes this by forcing the C locale in pfmt.
  . Fixed SUBTARGET nl and move netlist makefile to GCC-9
  . Preliminary Mac native OSD. Not working yet. This will compile, link and run a driver all the way to the first info screen, provided you use -video bgfx.
- VGM player: Fixed crash (ID 07412)
- Compiling
  . Migrate travis-ci to GCC-9
  . Fixed vrender0 link by moving mame\video\vrender0.cpp to devices\video\.
  . Fixed vsllvm build (sound\mas3507d.cpp). LLVM refuses to coerce the iterator to a pointer.
  . substr doesn't modify std::string, but erase does (tools\src2html.cpp).
  . Eliminated auto_alloc in model1.cpp, model2.cpp, video\midzeus.cpp, video\slapshot.cpp, video\taito_f3.cpp, video\zeus2.cpp and sound\multipcm.cpp
  . Bring static variables inside class in atlantis.cpp and midzeus.cpp
  . Changed osd_get_clipboard_text() to return std::string. This change has only been tested on Windows. The Un*x/Mac versions were made blindly; they might not even build. This needs to be checked prior to merging.
  . Added GCC build to AppVeyor. As tea-ci has been broken for quite a while now there has been no MINGW CI available. MINGW builds can be done in AppVeyor too. Tools build had to be disabled as it takes longer than the allowed 60 minutes. Wa,-mbig-obj was added to avoid "file too big" errors. Align AppVeyor GCC build configuration with travis. This will hopefully make the build fast enough not to miss the 60 minute maximum build time.
  . Get rid of assert_always - it's better to be explicit about what this thing is supposed to do. Get rid of a few MCFG_*_OVERRIDE.
- Debugger
  . Added -xchbytes option to UNIDASM swap bytes
  . Small cleanup and clarification to debugger\debuggdbstub.cpp. Old GDBs expected the regnum values for some registers to be hardcoded. This is no longer the case with GDB clients that support target.xml. We expect the GDB client to support target.xml (and won't support the 'g', 'G', 'p' and 'P' commands unless it is sent). Added mips (tested with indy_4610) and m68k (tested with macii). Added support for executing MAME debugger commands from the GDB client. It's now possible to send MAME debugger commands, such as "cheatinit", "snap", etc...
  . Use std::forward_list for breakpoint and registerpoint lists
  . Fixed QT debugger (debugger\qt\mainwindow.cpp)
  . Fixed debugger dump command for address-shifted spaces (debug\debugcmd.cpp)
