Also means "Multi-Video System," the "more-than-one-game-in-a-cabinet" setup used by SNK for Neo-Geo games in the arcade. MVS boards come in 1-, 2-, 4- or 6-slot models. Each slot fits a different game cartridge and can be selected at will from the cabinet's control panel. It's neat!

Not to be confused with AES, which is the home version of the Neo-Geo console.
