PCs shouldn't recognize Gamecube controllers as Xbox controllers... because they're not.
Most PC games don't need built-in controller support. I can take a list of keyboard defaults, plug them into JoyToKey within 1 minute, and make a game work with hundreds of controllers, using a layout that I explicitly consented to.
you said Gamecube controller with a "USB end".... so I assumed a third party gamecube controller, aka not an original GC... but a usb controller meant for pc use (those exists), because original gamecube controllers... dont have a USB end.
And reguardless most games dont have GC support bc its not common to use them outside fighting games, if you want to, just find a software that translates to xbox imput, theres plenty out there and my point was that you should already expect 99% of games to not have support for it anyway.
If I find a program that makes a controller appear as an Xbox device, will I be able to choose where buttons go?
I think it's way easier to just plug keyboard keys into JoyToKey.
It's true that I don't expect PC games to have built-in generic Gamecube controller recognition. Why include that when there might be over 600 PC compatible controllers?
pretty much yea! I do that myself actually, with both a original GC controller and a third party USB one, its a bit of a headache at the start, but works wonders once you have it figured it since most games are made with xbox controller in mind, you can just google "gamecube controller to xbox mapping"
