The Neo Geo Pocket was SNK's attempt to take on the Game Boy. While its sales were modest, it was a rather powerful hardware that got a good number of solid games. Like its far more popular rival, the Neo Geo Pocket first had a monochrome version, and then a Color version. But we won't bother with separate lists here, since the original was short-lived and only released in Japan, so it only got ten games. All the monochrome games are compatible with the Color system (and most got Color-upgraded re-releases), but only about half of the Color games are compatible with the monochrome system.[1]
