notes: |
MAME 2003-Plus is a libretro port of MAME 0.78 with backported drivers, bug fixes,
and new game support contributed after the original 0.78 snapshot. It targets
low-end hardware (Raspberry Pi, handhelds) while expanding game compatibility
beyond stock 0.78.
BIOS handling follows standard MAME conventions. Each arcade board with a shared
BIOS defines a parent ROM set. Game drivers reference this parent, and the emulator
merges the parent ZIP contents at load time.
BIOS ZIPs are searched in:
1. {content_dir}/ (same folder as the game ROM)
2. {system_dir}/mame2003-plus/ (libretro system subfolder)
3. {system_dir}/ (libretro system root)
ROM naming follows MAME 0.78 conventions with some updates from the Plus patches.
ROMs from modern MAME may not match expected CRC32/SHA1 values. Use a
mame2003-plus-specific romset for full compatibility.
Key differences from FBNeo and modern MAME:
- Neo Geo: uses mame.sm1 / mamelo.lo / sfix.sfx naming (not sm1.sm1 / 000-lo.lo)
- Neo Geo: Universe BIOS up to 4.0 (FBNeo has newer)
- PGM: uses pgm_p01s.rom naming (not pgm_p01s.u20)
- No NAOMI, no Atomiswave, no CPS-3 (too late for 0.78 era)
- ZN-1/ZN-2 boards present but marked NOT_WORKING
The Neo Geo set is the most critical BIOS for this core since nearly all Neo Geo
games work well. PGM and ST-V have partial support. Most ZN-based games are
flagged NOT_WORKING due to incomplete PlayStation emulation in 0.78.
