TG-16 was one of my favs.. I got a buttload of games and a whole lotta imports with a converter and other doodads. What's kind of sad though is I was in College (i.e. young and dumb) when the tg16 was hot.. so I shoplifted a good percentage of my games

Yeah yeah.. it was dumb. But hey, I was drunk
Don't forget that Nectaris: Military Madness (one of my all time favorites of all time

) was released for the psx as well. You should be able to find a copy pretty easily. Also, I'll take this opportunity to once again extoll the virtues of Xbox emulation. Hugo-X is up to v.9 I think and does a pretty good job of playing the majority of TG16/PCE/Turbo CD games on a convenient all in one console. Otherwise, if you're using a pc for your emu, then Magic Engine is the way to go. Yeah it's great playing it on the real thing, but like I always say, the real thing is the best, emu's are convenient.
My favs (yeah they're typical):
Military Madness
Blazing Lazers
Bonk series
Legendary Axe
Ninja Spirit
Street Fighter 2.. I went out of my way to travel to Japan to snag this.. so it's by default my preffered console version:D
