I bought a PC Engine Duo-R off ebay that had working cd but non working for hu-cards which is why it was a pretty good deal. Once it arrived I opened it up to find somebody had tried to install a region mod and wasn't successful.
Anyway one of the pins from the card slot is completely missing and I think best option would be to replace the whole card slot. Can I use the card slot from a TurboGrafx 16? or is my only option from a non working PC Engine, PC Engine Duo/Duo-R?
