I have an arcade run on raspberry pi 3 flashed with RetroPie 4.4. I have 2 Xin Mo Dual joysticks connected.

  • JoyStick : Xinmo
  • Controller : Xinmo USB Encoder

enter image description here

Note: Both controllers wired perfectly. I've tested all the buttons on my Windows PC > Control Panel (before plug in the usb into the Pi).

I tried to retroArch and bind user 2

I kept getting.

Error saving autoconf file

Do I need to install any extra driver for it to recognize?

Do I need to run any commands or enabled anything feature on my Pi?


How would one go about and debug this further ?

I'm open to any suggestions at this moment.

Any hints/suggestions / helps on this be will be much appreciated!

  • That interface used to connect it to RasPi?
