I´ve just started my first arcade project but got some problem with the controllers that I hope you guys could have a solution to. 😉
Built an prototype and attached all the Sanwa buttons och the joystick to the USB-controller board. After that I installed RetroPie on my Raspberry Pi 2 Model B and everything works fine. The joystick and all the controller buttons works fine in the RetroPie OS. But when I start the NES or SNES emulator the Start/Select buttons doesn´t work and the A/B buttons are no longer on the right place as I set in the configuration. What´s up with that? 🙂 Do I have to change something in the configuration file to set up the controllers for each emulator?
