Neo Geo Pocket is a portable console from SNK. It was launched in Japan towards 1998, and discontinued in 1999, to give way to the Neo Geo Pocket Color, due to the low sales of the monochrome system. Although he had a short life, there are some games for the system that are worth mentioning as Samurai Shodown and King of Fighters R-1.
In the Neo Geo Pocket you can play several of the new games in color. There are notable exceptions such as Sonic the Hedgehog Pocket Adventure or SNK vs. Capcom: Match Of The Millennium. The Neo Geo Pocket Color is fully compatible with the old Neo Geo Pocket games.
