As for the hueys, no. Not unless it uses 1. an adaptor 2. got a region mod. If you attach a CD-ROM to it, you can play any CD games you like from any of the two countries (as long you have the appropriate system/arcade card inserted).
NEC PC engine / Core GRAFX (TurboGrafx-16) game console (Japan version) with 5 Games for Sale > Games Includes: Hit The Ice, NINJA GAIDEN (Ninja Ryukenden), Vigilante, PC GENJIN, Power League $40 should i jump on it ?
That's quite cheap, are the games boxed? I'd go for it if the console looks ok on pictures and it's been tested.
Are the games complete? If they are, I can pretty much say your getting a great deal. Even with out the games, your still doing fairly well (by non-japanese standards anyway)
