I forgot what I had to do to get it to work, but practically every Neo Geo MVS game has the ROMS and Neogeo BIOS and can be made to run in MAME.

So you don't necessarily have to use the jarate emulator that is included if you don't want to do so...

NOTE that doesn'tt work with non MVS Neo Geo games like KOF 98, the modern 2002, etc...
