SNK's first two products using the Neo Geo name are an arcade system called the Neo Geo
Multi Video System (MVS) and a companion console called the
Advanced Entertainment System (AES), both released in 1990. The MVS offers arcade operators the ability to put up to six different arcade games into a single cabinet, a key economic consideration for operators with limited floorspace. It comes in many different cabinets but basically consists of an add on board that can be linked to a standard
JAMMA system.
The Advanced Entertainment System (AES), originally known just as the
Neo Geo, is the first
video game console in the family. The hardware features comparatively colorful
2D graphics. The hardware was in part designed by
Alpha Denshi (later ADK).
Initially, the home system was only available for
rent to commercial establishments, such as
hotel chains, bars and restaurants, and other venues. When customer response indicated that some gamers were willing to buy a US$650 console, SNK expanded sales and marketing into the home console market. The Neo Geo console was officially launched on 31 January 1990 in
Osaka,
Japan. The AES is identical to its arcade counterpart, the MVS, so arcade games released for the home market are nearly identical conversions.
