The Forgotten

The Neo Geo Pocket was SNK's original hand held system. It was released in Japan in late 1998, and discontinued in 1999, with the advent of the Neo Geo Pocket Color, due to lower than expected sales with the Monochrome Neo Geo Pocket.

In 1987, Epyx created the Handy; a device that would turn into the Atari Lynx in 1989. It was the first color portable ever made, as well as the first with a backlit screen. It featured a color LCD screen with backlight, networking support with up to 17 other players, and advanced hardware that allowed the zooming and scaling of sprites. The Lynx could also be turned upside down to accommodate left-handed players. However, all these features came at a very high price point, which drove consumers to seek cheaper alternatives. The Lynx was also very unwieldy (due to focus groups requesting the machine be bigger so it felt like they "got their money's worth"), consumed batteries very quickly and lacked the third-party support of the alternatives. Due to a high price, short battery life, production shortages, a dearth of compelling games, and Nintendo's aggressive marketing campaign, and despite a redesign in 1991, the Lynx became a commercial failure.

The Sega Game Gear is a handheld game console and was Sega's response to Nintendo's Game Boy. It is the third commercially available color handheld console, after the Atari Lynx and the Turbo Express. Work began on the console in 1989 under the codename "Project Mercury", and the system was released in Japan on October 6, 1990. It was released in North America and Europe in 1991 and in Australia in 1992. Support for the Game Gear was dropped in early 1997.
