- Floppy
  . Minimal improvements on the disk handling. Keeping the 35 tracks drive as an option. Reducing the crashes a bit more. This helps matching the form_factor and the parameters found in the TeleDisk images, thus exiting before a serious crash. It is NOT enough to improve the 8" disk image handling, nor it solves all the stability problems, but it is a tiny step forwards (formats\td0_dsk.cpp).

- expro02.cpp and galpanic.cpp: Added missing 2nd button to includes\galpnipt.h (ID 06937). Note: Turn on 'Service Mode' dipswitch, reset and press P1 START. Pressing the second button is not reflected on screen (appears as "Shot 2"). The main game doesn't use it, but it's needed for the "Animation Test" that can also be turned on in the dipswitches.
- gaelco2.cpp: Added pinout information for World Rally 2 and REF.950906 PCB layout for Touch & Go
- galivan.cpp and terracre.cpp
  . Rewrote NB1412M2 protection into a device
  . Fixed protection in clone Ufo Robo Dangar (9/26/1986, Japan) (Game now playable). Note: Game has unemulated protection at I/Os 0x80-1 for missing sprites. This is a Nichibutsu 1412M2, which is the same chip used in TerraCresta and Cop01 driver. The protection here is used for a code snippet at 0xf9c0, that of course is the sprite handling. The code snippet is sum8 with 0x27 at 0x9d74 so no, the later Dangar US version snippet doesn't work.
- guab.cpp: Added RS-232 port and updated notes
- gundealr.cpp: Cleanups

  . Start splitting up the state classes for the different variants properly
  . Split into real models: Moved common stuff (mostly video) into a base memory map. Split common edge connector inputs into JAMMA and MVS. Added clones with different numbers of game slots, edge connector, controller ports, memory card and speakers. Based fixed-software drivers on MV-1 JAMMA board configuration. Removed memory card and controller ports from single-PCB games and converted to mono output. Coin lockouts/counters still not connected, and LED/EL output isn't suppressed for variants that lack it. Suppress leading space in RAM option names.
  . Further improvements: Removed LEDs/lamps from configurations that lack them. Hooked up coin counters and lockouts. Improved I/O register mapping. Added controller detection connections for AES. Hooked up SPI-like outputs on SIT board used by irrmaze.

- ssv.cpp: Simplify ST010 ROM loading
- stv.cpp
  . Fixed regression with Cotton 2 backgrounds in stage 2 onward (video\stvvdp2.cpp; enables ROZ mode 3 without neither rotation parameter windows nor actual rotation parameters). This fixed also the corrupt background in Virtua Fighter Kids (ID 06886).
  . Preliminary implementation of PMOD 7 (gouraud + half transparent) (video\stvvdp1.cpp), fixes (MESS) Sega Saturn 'Lupin the 3rd Pyramid no Kenja' enemy shadows.
  . ROZ windows applies per screen output not per bitmap (video\stvvdp2.cpp), fixes at least Batman Forever character select & the Riddler final stage graphics.
  . Fixed RBG0 cache map range (video\stvvdp2.cpp), fixes (MESS) Head On graphics update in Sega Memorial Collection 1.
  . Fixed t1_mode_w in address map of achine\sega_scu.cpp

- Blades of Steel: Soundlatch modernization
- Contra: Acknowledge sound IRQ
- DJ Boy: Added generic_latch_8_device for comms. Added stereo sound output, because PCB has stereo sound output connector and OKI is connected per each output. Cleanup OKI ROM loading and gfxdecode. Fixed sound output level. Fixed tags. Fixed MCU acknowledge writes.
- Dora-chan: Better protection and cleanup
- F-1 Dream: Decapped and dumped F-1 Dream I8751 MCU (Game now playable)
- Fever Soccer: Eliminated set_lamp_value and MCFG_CPU_VBLANK_INT
- Fire Fox: Cleanups. Added output finder/object finder. Reduced runtime tag lookups.

- MAME
  . VIDEO RENDERING SYSTEM
    . Cleaner handling of layout parsing errors (emu\rendlay.cpp and layout\noscreens.lay)
    . Bulk conversion
      . Converted MCFG_DEVICE_VBLANK_INT to MCFG_SCREEN_VBLANK_CALLBACK
      . Use MCFG_SCREEN_VBLANK_CALLBACK instead of MCFG_CPU_VBLANK_INT
      . Replaced MCFG_CPU_VBLANK_INT with line callbacks
      . Use MC6845 sync callback instead of MCFG_CPU_VBLANK_INT in funworld.cpp, goldnpkr.cpp and madalien.cpp
      . Use MC6845 for vertical interrupt generation in gluck2.cpp, mpu12wbk.cpp and ssingles.cpp
      . Added some plausible raw params and eliminated MCFG_CPU_VBLANK_INT in twins.cpp
    . Removed underscores from template parameter names (emu\emupal.h)
  . DEVICES
    . Allow machine configuration to specify BIOS easily, move default BIOS selection into device configuration complete.
    . Removed unnecessary device_t::memory() (drivers\bublbobl.cpp, missb2.cpp and superqix.cpp)
    . Removed safe_pc() and safe_pcbase() (emu\distate.h)
  . Show RAM options in XML output that can actually be controlled from the command line - the others are practically useless (machine\ram.cpp and mame\info.cpp). Expose RAM size in "minimaws".
  . Get rid of more uses of inefficient output methods (drivers\de_2.cpp, de_3.cpp, flicker.cpp, jankenmn.cpp and machine\decopincpu.h)
  . Removed emucore from external tools (scripts\src\tools.lua)
  . Save a ref to waiting co-routine to prevent it from being gc'd (mame\luaengine.cpp)
  . PLUGINS: Require returns true if package returns nil (plugins\data\database.lua)
  . Moved some not-directly-emulation-related helpers to lib\util\coretmpl.h and disasmintf.h, further extricate emu.h from tools.
  . MEMORY SYSTEM
    . Allow for an address shift (machine\bankdev.cpp)
    . Fixed changing_bits < default_lowbits_mask (emu\emumem.cpp). Fixed fencepost in memory_manager::region_containing, which caused regions to be registered for state saving (emu\emumem.cpp).
    . Relaxed constraints on address mirroring/global mask combinations. Mirror bits are now allowed to fall outside the driver-specified global mask, though memory map validation requires that they cover the entire masked-out portions of the address space if any do. This change is intended to expedite debugging of software written for the TMPZ84C015 or similar Z80-based controllers which use 8-bit I/O addressing for the on-chip peripherals but may use either 8-bit or 16-bit addressing externally (emu\addrmap.cpp).
    . Completely eliminated address map macros
  . PLUGINS
    . Work around small issue in conversion (plugins\cheat\cheat_xml.lua)
    . Changed indentation in save file by request and sort the output file (plugins\portname\init.lua)
    . Fixed cpu tags and print detailed errors (hiscore\hiscore.dat and init.lua)
- SDLMAME: Set SO_REUSEADDR in posixsocket. Without it you have to wait until the socket is moved out of the TIME_WAIT state, which can take quite a while. This is pretty anoying when using mame with serial ports forwarded via TCP (modules\file\posixsocket.cpp).
- Compiling
  . Added possibility of building using system pugixml
  . Fixed issues with CHD loading under Emscripten (scripts\src\main.lua)
- Debugger
  . Documented debugger expression number syntax (debugger\expressions.rst)
  . Moved around the debugger hooks to get a small but measurable performance increase
  . Fixed scheduling session events from debugger (debug\debugcpu.cpp)
  . Added suspend and resume debugger commands for suspending and resuming scheduled devices (debug\debugcmd.cpp)
  . Documented dumpo command (debug\debughlp.cpp)
