@Fruitybit Nevermind, it works. The Button was just simply broken. Got another one, works like a charm

Hi @shukuyen ,

Sorry, I didn't make a tutorial but it was all pretty straightforward in the end.
I gutted an old Nes and dumped everything in :)

Parts used:

Rpi3 + microsd Raphnet dual nes to usb Petrockblock's controlblock and nylon posts Wiring

The hardware part was the easiest part tbh.
If you get it all wiredup i can make an image of my sd. That way you shouldnt have to configure anything :)

Thanks @petrockblog!
I just tried it out using some stipped wire.
Connecting Plyr 1 GND or Plyr 2 GND with Player 1 B for a short moment will indeed "reset" out of the current running game!
