Supports ~2000 arcade games from the 0.37b5 ROM set.\n\nBIOS handling follows MAME 0.37b5 conventions. Shared BIOS files are packaged\nas parent ROM ZIPs (e.g. neogeo.zip) and placed in the ROM directory alongside\ngame ROMs. The core searches only the ROM directory for ROMs and BIOS sets.\n\nSamples (per-game WAV files) are loaded from system_dir/mame2000/samples/.\nThey provide sound effects for certain games and are optional.\n\nhiscore.dat, history.dat and mameinfo.dat are loaded from the ROM directory.\ncheat.dat is loaded from system_dir/mame2000/cheat/.\nhiscore.dat and cheat.dat are bundled in the core repo (metadata/).\n",
