Sega Nomad

The Genesis in your pocket — for about two hours, then please find a power outlet.

A North-America-only handheld that played any Genesis cartridge on a 3.25-inch backlit colour screen, with a TV-out for when the battery gave up. Launched in 1995 just as Sega's focus pivoted to the Saturn, it got almost no marketing and disappeared quickly. Today it's one of Sega's most distinctive — and increasingly collectible — pieces of hardware.
