Neo Geo Pocket
The Neo Geo Pocket was SNK's original handheld system. It was released in Japan in late 1998 and featured a monochrome (one-color) display. Because its sales were fewer than the expected number, it was discontinued in 1999 in favor of the Neo Geo Pocket Color, which was later released in North America and Europe. In 2001, the Neo Geo family ended. It was briefly revived 11 years later with the Neo Geo X.
