So far from what I have read, the two are one in the same. TG16 - US Name, PC Engine - Japan.

I have a TG-16, want the CD Add-On (So i can play my copy of Dracula X for PC Engine). Also was looking at getting the Super System Card to addon to make it more like a real Turbo Duo.

That being said, can I use the Super System Card imported from Japan? They seem to be a lot cheaper.

Also, if anyone has any better info on the TG16/PC Engine lay it on me. I never really took too much time to learn anything about the thing and its one of the next setups Id like to have more of
