Taito FX-1B (zn.c): the 12 sets of current MAME (raystorm, raystormo, raystormu, raystormj, ftimpcta, ftimpact, ftimpactu, ftimpactj, gdarius2, gdarius, gdariusu, gdariusj) on the FX-1 board of #2095, with 2 MB VRAM on G-Darius, 512 bytes of FRAM kept with the EEPROM, and the Taito Zoom sound board. The old FX-1B sets and machine are replaced; taitofx1 stays as the parent of beastrzb. Taito Zoom (sndhrdw/taitozoom.c): MN10200 sound CPU, ZSG-2 and TMS57002 DSP, as MAME taito_zm. The DSP runs one sample at a time from the stream, kept going while its FIFO drains so the FIFO-empty line (MN10200 IRQ 1) falls as on the board. Save states keep the time left on that kick. New chips, ported from current MAME to C89: - cpu/mn10200: Panasonic MN10200. A timer nobody sees (irq disabled with the request up, nothing cascaded on it) sleeps instead of firing: the Zoom program runs one as a 240 kHz baud clock, which cut the timeslices of every CPU. It keeps its phase and wakes when its irq control or the timer above it change. - sound/zsg2: ZOOM ZSG-2. - cpu/tms57002: TI TMS57002 DASP (API prefixed tms57002dsp_, Konami GX has its own tms57002_ stubs). Output identical to the MAME C++ core on the same recorded input. PSX GPU (psx_vidhrdw.c): the GP0 commands missing from the parser, as MAME (0x42/43, 0x4a/4e, 0x51/53, 0x5a/5e, 0x69-6b, 0x6c-6f textured dot, 0x70-73 and 0x78-7b flat 8x8 / 16x16 rectangles, 0x75/76, 0x7d/7e). Their words were taken as commands: Ray Storm turned them into huge fills (15 fps), other ZN games lost bits of their HUD. Lines and dots also do semi-transparency now.

What is MAME 2003-Plus?
MAME 2003-Plus (also referred to as MAME 2003+ and mame2003-plus) is a libretro arcade system emulator core with an emphasis on high performance and broad compatibility with mobile devices, single board computers, embedded systems, and similar platforms.
In order to take advantage of the performance and lower hardware requirements of an earlier MAME architecture, MAME 2003-Plus began with the MAME 2003 codebase which is itself derived from xmame 0.78. Upon that base, MAME 2003-Plus contributors have backported support for an additional 350 games, as well as other functionality not originally present in the underlying codebase.

Romsets and how to build them for this core
mame2003-plus was originally built from the MAME 0.78 codebase, meaning that 95% or more of MAME 0.78 romsets will work as-is in mame2003-plus, where they immediately benefit from its bugfixes and other improvements. In order to play the new games and games which received ROM updates in mame2003-plus, you will need to find or build the correct romsets.
