Sega Genesis Nomad (1995)
Sega released the bulky, battery-hungry Nomad at a bad time in the company's history. It had already oversaturated the market with eight incompatible platforms: Genesis, Sega CD, 32X, 32X CD, Game Gear, Pico, Saturn, and (in some markets) Master System. As a result, few consumers paid attention to the Nomad launch, and the system sold poorly. Still, the Nomad was novel in that it could play regular Sega Genesis cartridges.
