Technical notes

Frozen snapshot of MAME 0.78 (xmame, January 2003). Stock version without the Plus patches. Targets low-end hardware (Raspberry Pi, SBCs).

BIOS ZIPs are loaded from {content_dir}/ (same folder as the game ROM).

Data files (hiscore.dat, cheat.dat, history.dat, mameinfo.dat) are loaded from system_dir/mame2003/. Samples from system_dir/mame2003/samples/.

Neo Geo uses 7 official BIOS variants. Universe BIOS is commented out in the stock source (available in mame2003_plus).

ROM naming follows MAME 0.78 conventions.
