Cathode Ray Dude - CRD | NES to PC Engine Gamepad Mod (Cross-Pollination) @CathodeRayDude | Uploaded February 2020 | Updated October 2024, 1 week ago.
This video is about a project I undertook to make an easy way for anyone to convert an NES gamepad to work on the PC Engine, since the PCE has a really detestable controller if you ask me. The parts are available inexpensively on Oshpark and Digikey and you can perform this mod yourself for less than $10.

I believe this mod will work on the Turbografx-16 if you just use a full-size DIN-8 instead of a mini-DIN-8 cable; the pinouts appear to be identical, but attempt this at your own risk. Let me know if you try it and it works!

If anyone is interested in a video about how to design the circuit and board, let me know and I'll put one together. If anyone's interested in a variant with turbo, I'd be willing to look into it but would appreciate a few bucks to cover R&D.

My head showed up in a few shots unfortunately, and there are a couple steps I had to cut because the footage was entirely head-focused. I hope it doesn't disrupt things too much!
