XInput is somehow causing a ghost 2nd controller that just doesn't exist.
I can't find a way to disable the 2nd pad neither in DsHidMini Control, nor the Device Manager.
Any other HID Device Mode causes a duplicated input of different buttons from the same controller, the most accurate I was able to find was the XInput, but it's mapping a 2 pad that it's just not there, and causing a mess in most games.
