Neo Geo:Neo Geo Mods Wiki



The Neo Geo is a cartridge-based arcade system from the fourth generation of video game consoles. The console was launched to arcades as the Multi Video System (MVS) in Japan on April 26th, 1990 followed by releases in North America (August 22nd, 1990), and Europe (1991). Variants of the arcade console may have 1, 2, 4, or 6 cartridge slots for games that can be chosen by the player. Many people "consolize" MVS boards to be playable on a home television by either using a JAMMA-based "supergun" or manually wiring the needed parts.

On July 1st, 1991, the console was launched in a different form factor to the home market as the Advanced Entertainment System (AES), becoming the most powerful machine of the fourth generation of consoles. A version of the AES that uses CDs instead of cartridges — the Neo Geo CD — was released in 1994 worldwide along with a front-loading variant in Japan. A slightly improved "Neo Geo CDZ" was then released in Japan in 1996, offering a faster-loading CD drive but including a overheating flaw. A handful of exclusive titles were released straight to Neo Geo CD.
