Neo-Geo is the name of a cartridge-based arcade and home video game system released in 1990 by Japanese game company SNK. The system offered comparatively colorful 2D graphics and high-quality sound. A major platform for arcade games at the time, the system was also available as a costly home console. The two versions of the system were known as the AES (Advanced Entertainment System, the Home Version) and the MVS (Multi Video System, the Arcade Version).
