MAME 2003-Plus

MAME 2003-Plus emulates SNK Neo Geo MVS, SNK Neo Geo AES, IGS PolyGame Master and 22 more systems. It reads 37 files, 23 of them required: without a required file it does not start games. A required file is needed only by the machines that use it. Each file below cites the line of source code that reads it.

Its BIOS and game sets must come from the MAME 0.78 (plus backports) romset. Which version each core reads.

Install this emulator's files

The installer finds your setup and its BIOS folder, then downloads only the files this emulator reads there and checks each one.

Open the Start menu. Type PowerShell and open it. Paste the line. Press Enter.

Technical 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 must be in {content_dir}/ (same folder as the game ROMs). The core resolves parent ROMs by walking the clone_of chain within the content directory only (osd_get_path returns content_path for FILETYPE_ROM).

ROM naming follows MAME 0.78 conventions with some updates from the Plus patches. Requires a mame2003-plus-specific romset for full CRC32/SHA1 compatibility.

Neo Geo uses mame.sm1, mamelo.lo, sfix.sfx naming. PGM uses pgm_p01s.rom naming. ZN-1/ZN-2 sets are named after the board BIOS (coh1000c, coh3002c, ...) and each BIOS set carries the CAT702 key of the main board. Namco System 11 games run the C76 BIOS from namcoc76.zip. PGM and ST-V have partial support.

Data files go in {system_dir}/mame2003-plus/. Samples in samples/ subfolder, artwork in artwork/ subfolder (both per-game ZIPs). hiscore.dat is compiled into the binary and auto-generated on first run if absent.
