The Neo Geo Pocket is a series of handheld game consoles developed and manufactured by Japanese video game company SNK between 1998 and 2001. The first model, the monochrome Neo Geo Pocket, was released in Japan in October 1998, marking SNK's entry into the handheld gaming market and competing with Nintendo's long-running Game Boy line. It was quickly superseded by the more mass-produced Neo Geo Pocket Color in 1999, a more widely produced model featuring a color display and full backward compatibility with the games for the original model.
