I have a Switch Pro Controller paired to a Raspberry Pi 3 Model B+ to play games in RetroPie.
I would like the option to use the leftthumb stick on my controller as a d-pad when playing systems that didn’t support analog control. (NES, SNES, Genesis).
I considered rebinding my thumbstick to the d-pad, but that would mean I can’t use the thumbstick on systems with analogue controls such as N64 or PS1. (Preferably, I would also like my d-pad to continue working as a d-pad.)
How can I configure RetroPie to use my left thumbstick as a d-pad for games that don’t support analog sticks?
