Received my new Picade hat today and followed the setup instructions on a retropie image that was already being used. Wired up the controls and when I push the soft power button, the system boots to retropie. I go to the controls setup and the buttons and joystick are not seen and cannot be configured. The soft power button also will not shut down the system and this has to be done the usual way with a keyboard command.
Also purchased a Picade pcb (not hat) and connected this and this works straight away with the same retropie image.
Any suggestions would be very welcome as this is going into a bartop arcade machine made from lego that I hope to show off at an event on Wednesday.
