I have assembled and tested Simple Genesis 3-button to PC-Engine adapters which were kindly designed by rattboi
As per schematics, microcontroller was not used, that means no addition significant lag existed. I tested them with 8bitdo MD30 bluetooth and 2.4 GHz controllers and receivers. They work flawlessly. Also I include extention wire to the package. So it's plug and play and You can finally play Your favorite Splatterhouse or Bonk laying on Your sofa with wireless controller.
I left some of them for myself and friend of mine, and the rest 6 ea are up for sale. The price will be 29 USD + 6 USD shipping with tracking number. The deal will be insured through paypal or I can sell it through ebay but that will add ebay fee.
Let me know if You are interested in.
