It took me forever to find one of these things, but man are they worth it. I finally found one for $25 with a few games. A portable Genesis is a pretty novel idea, it's just a shame that portable in the Nomad's case means "without a TV" and not "without an AC adapter plugged in". It goes through 6 AAs in 2 hours.
Still, it's better than those clone systems with messed up sounds. I just played Ecco the Dolphin on it and it was perfect. Only thing wrong with is the screen is that since it's an early active matrix screen, really really fast sequences in games blur. Most games are fine though. Anyone else play this awesome thing?
I have one of those. They're kickass, man.
