Thanks for the quik reply.
Did some searching and find Jap>US converter.
Since all varitions PC engine, Supergrafx,... are hucard i think it will work.
Except that the supergrafx is more powerfull (for the few games that came out for it) but i don't think that will get in the way to make it work as it is backwards compatible.
Hope to get my supergrafx.
Have a turboexpress but looking forward playing it on the big screen.
