Improvement: Swap A<->B (and X<->Y) #6
Description
Would be great if you could add a setting or script to swap A and B (also X and Y) buttons.
I'm aware that Gmenu2x and all the emulators allow to remap buttons (while some other apps don't), however what I'd actually like to achieve - is that on software level all the mappings stay as they are, but that I could swap the buttons on the device level.
