I have just had the RetroPie GPIO Adapter turn up today and soldered on the few bits that needed it. I pluged into the RaspberryPi and ran the retropie_setup.sh to install the drivers (which seemed to go okay) and then enable it with SNES bindings.
As far as I can see there were no errors at either stage but i have no js0/1 in /dev/input/. The second stage said that it had detected V1 of the board.
Am I missing something out? How can I check that the files and interface are all working correctly?
