Lynx:Lynx Mods Wiki
The Atari Lynx is a handheld console from the fourth generation of video game consoles. The console was released on September 1st, 1989 in North America followed by Europe and Japan in 1990. The Lynx was the first handheld console with a color LCD screen, the first console with hardware support for sprite zooming and distortion, and also featured a button combo to flip the screen, allowing play using the directional pad with the right hand. A model revision — the Lynx II — was later released which came in a smaller form factor with better battery life, stereo audio, and a clearer backlit screen. Up to 15 Lynx consoles could be networked together using cables with its Comlynx system for multiplayer games.
