Hi there. So I just got myself a Raspberry Pi 3 and turned it into a RetroPie. I've got everything up and running. My 8Bitdo SNES controller and my Xbox 360 controller work. The problem is, I need certain buttons switched around for certain systems and certain games. I can click the hotkey in game to change the controls and then I save them. And it works perfectly until I exit the game. No matter what I do, I can't get it to save. Even though I click save and have specified for it to save on exit in Retroarch. Does anyone have any ideas? It's really annoying.
