I have an arcade run on raspberry pi 3 flashed with RetroPie 4.4. I have 2 Xin Mo Dual joysticks connected. I would like to connected 1 more USB input controller and use it as a default controller when I play NES or SNES.
Right now my Arcade only recognize Xin Mo Dual joysticks as default.
How do I configure my Pi to use a certain controller as default base on emulator ?
