Button Assignment

Using: https://hardwaretester.com/gamepad

You can use Raphnet Adapter Management Tool to set whether the D-pad is mapped to joystick axes or buttons, axes is the default.

The button mapping is a bit weird, so you can't just swap a controller for a 360 one or something without remapping.
