The MVS (Multi Video System), as the Neo Geo was known to the coin-op industry, offered arcade operators the ability to put up to 6 different arcade titles into a single cabinet, a key economic consideration for operators with limited floorspace. With its games stored on self-contained cartridges, a game-cabinet could be exchanged for a different game-title by swapping the game's ROM-cartridge and cabinet artwork. Several popular franchise-series, including Fatal Fury, The King of Fighters, Metal Slug and Samurai Shodown, were released for the platform.[1]
Hardware
Available in 1 Slot, 2 Slot, 4 Slot and 6-slot variants. Some later games also came on dedicated boards.
