My latest batch:
Pitfall II (way better than 1)
Jungle Hunt (pretty solid game)
Galaxian (it's all right. I'm impressed with the lack of flickering)
Video Olympics (just waiting for a multi-player session for this one)
Defender (a whole lot of flickering. Kinda hard to tell what's going on)
Arcade Pinball (just okay)
Moon patrol (pretty legit. More fun than the screenshots make it look)
Spider-man (pretty challenging but I like it)
Omega Race (apparently requires a special controller?)
Dig Dug (pun intended but I really dig this version)
