I recently picked up a PC Engine Duo at a steal of a price, but it didn't come with a controller. Does anyone have a spare they'd like to sell me? I do have controllers for my TG-16, but it's the wrong plug so if there's such a thing as a converter that would also work, I'd be interested in hearing about that, too.
Talk to Keith Courage. He hooked me up with a PC Engine to TurboGrafx Turbo Tap! Now I can use all five of my TurboGRAFX controllers on my Japanese Duo.
He did help me fine-tune my TurboGrafx-CD into working again. I'll ask.
