The Retro Duo Portable NES/SNES Game System is a hardcore gamers dream come true. Take a trip down memory lane and play some classics like Super Mario World, Chrono Trigger and StarFox! Not only is this unit portable, you can also hook it up to a large screen tv if you want. The system also comes with two extension controllers so you can play 2 player games. An adapter can be purchased which will allow you to play sega genesis games as well.
