The Sega Nomad was Sega's second Handheld console. It was only sold in North America and Japan which played Sega Genesis game cartridges. It was based on the Japanese Sega Mega Jet despite having a strong resemblance to the Sega Game Gear and featured a built-in color screen. The Nomad was never officially released in PAL territories such as Europe and Australia. Its codename during development was Project Venus, as per Sega's policy at the time of codenaming their systems after planets.
