I use a Nintendo Switch Pro Controller via Bluetooth on Windows 10, and it doesn't seem to respond to button inputs at all.
Unfortunelately, I can't afford to buy a PS4 controller to have a compatible controller. If I could, that money would go to fixing my SSBU Switch bundle Collector Edition JoyCons, or my own game project, depending on the source of the income.
I do have a Logitech Gamepad, however, the XBox button layout it uses is different from the Switch button layout, so if it does work, I will repeatedly get A\B and X\Y mixed up, which can cause numerous problems…
However, all this aside, I am happy to know that there are controllers that do work, but am annoyed the only one I have with the correct layout does not.
