Not sure how to access this retroarch menu?
Hotkey+x will open the retroarch menu while youre in game. Then go to controls and remap as you like and then you can save it as a core remap. Remapping here won't influence your mappings in the standalone emulator because it doesn't use the retroarch controls.
