The Nintendo controller has the same button names as the Xbox (defacto standard PC controller) but different placement. If buttons are mapped based on physical position but using Xbox glyphs, Nintendo buttons are called out incorrectly. If buttons are mapped based on name, Nintendo buttons are called out correctly but the controls are positioned weird and displayed wrong if displayed on screen in button layout. PS controllers have no chance of making sense when dealing with lazy devs.
It's super easy to implement multiple sets of glyphs and mappings for the three main controller types. Pretty much anything else is a clone of those three. I have no clue why so many don't bother.
