Neo Geo bios Info

WHAT IS NEO GEO BIOS AND WHY IS IT NEEDED?

Neo Geo bios is a small program element common to all Neo Geo MVS hardware games that is nevertheless essential in order for the games to boot up. No bios = no games!!!

The bios file, neogeo.zip, needs to be in the roms folder with the rest of the game files. You only need one copy of the file (leave it zipped!) and it will work for all Neo Geo arcade games. Doing that will go a long way towards solving problems with getting Neo Geo games to work in MAME.

However, it's important to realize that the MAME project is a continual WIP and not every version of game files are gonna be compatible with every version of MAME. Matching MAME32 Plus Plus 0.119 with sites like romnation is a good first step towards better compatibility.
