@XyzzySqrl i'm reminded of my experience trying to play The Journeyman Project: Pegasus Prime via Mac emulation back in the day
the keybinds made no fucking sense (for a game that was originally intended as a console port of a point-and-click adventure!) and i can only assume what happened was they decided the best way to map a PS controller to a keyboard was to treat the controller itself as a map of what the keyboard arrangement should look like
