My friend has a working US CD-ROM2 unit and connector to the TG16 unit but no US system card or converter. I have a few spare white PCE Engines and IFUs, so I was going to give him one of each so he could use his CD ROM2 without spending any more money. I've heard this would work fine without any mods, but is this correct? He can just use a JP Super System 3.0 card to play Super CDs, right?
