      I de-soldered the ports on the controller plate and made a layout, can anyone check if this is correct? Why does the comment above and wiki say to wire it to 3.3v while the controller needs 5v? I already have a RF module wired up to the red pin on the picture. I will get some rainbow jumper wires and solder them directly into the holes.

        @denisuu Because it runs fine with 3.3v. I also fixed my issue with the pad working in retropie setup. I had to set the controller to Player 1. If you have any issues, please read the guide: https://github.com/retropie/retropie-setup/wiki/GPIO-Modules#gamecon_gpio_rpi

            I took some parts out of a old computer (header pins & audio connection cable) and soldered them onto the SNES plate. I used the recommended GPIO setup from the gamecon installer.

            But only button A is working on player 2. I'm pretty sure my soldering is good, and I suppose the wire thickness is also ok since the original ribon cable is very small. I read something about the 3 different revisions of controllers.

            The question is what can I do about it?

              @denisuu You need to bridge both clocks for both pads to work. I was having issues when I was using thin wires. I'm using whatever thickness IDE cables are.

                Yea both clock's are bridged I checked all connections in the front ports with the RPI GPIO pins and the wiring is good. But when I push B it shows as if I push all buttons at once in jstest. IDE cables are very thin for sure these wire's are thicker. But maybe the cable is too long it's 67cm.

                I will reinstall retropie, find thicker wires and try again.

                Controller 2 doesn't want to do anything at all I tried (GPIO7=Pin26 or GPIO3=Pin05)
                With gamecon_gpio_rpi map=0,0,1,1,0,0 and 0,0,1,0,0,1...

                  I'm using the default config retropie has for the gamecon driver which is 2 snes controllers. My wires are around half as long as of yours.
                  Pin1=3.3v
                  Pin5=D2
                  Pin6=GND
                  Pin7=D1
                  Pin19=C1/C2
                  Pin23=L

                    That works thanks!! It's a completely different layout then the Wiki and driver installer suggest tough. Also it turned out one of my controllers just isn't working :P

                      The gamecon installer pinout is almost correct except for the player pins need to be switched around. No need for a tutorial but ok...

                        @Darksavior I realize that now by looking at the picture again that I was just stupid. I put clock and latch at the wrong place the whole time because I just counted one empty pin from the bottom. Anyway I'm happy It's finally working.
