Thanks for reply! The GPIO adapter works great on my older Raspberry from 2012, but not on my latest RaspberryPI v2, I have a 1.2 GPIO adapter and set so in Retropie-Setup… Emulationstation is detecting the “gamepad” but there is no response when I press the buttons, same goes for testButton app, it wont register any push

I also tried the update https://github.com/petrockblog/SNESDev-RPi#installation.

Any ideas? :-)
