Term describing cartridges for the Neo Geo home system (also known as home carts). Stands for Advanced Entertainment System. The term originally described the system itself: the English language logo for the Neo Geo had “Advanced Entertainment System” stamped between the Neo and Geo -fulfilling the Japanese love for adding superlatives to their product descriptions. The term has now become a popular short hand for describing a Home Cartridge (i.e. “I traded my Robo Army CD for his Metal Slug 3 AES.”). AES carts are not compatible with the arcade (MVS) system (except by conversion).
MVS/MVS Cartridge
Term describing cartridges for the Neo Geo arcade system. Stands for Multi Video System. The term is actually part of the name of the arcade system: the Neo Geo Multi Video System (See Neo Geo MVS). Although they contain the same “guts” (ROM chips and such), they are not compatible with the home system (different size outputs). They manufacturer did this to prevent arcade operators from buying the then cheaper home carts (MVS carts debut in the $500-$1200+ range, home carts in the $180-$300 range).
