I recently finished my cocktail arcade cabinet powered by RPI 2b. I installed Retropie 3 and I configured the controls with Retroarch. It seems that only MAME works OK with the controller. On the SNES emulator for example, only the buttons work but the joystick is irresponsive. I think I need to edit the Retroarch config file but I don’t know what to do.
Any advice would be helpful.
