There are some patches still around (would have to look them up) and
they work. The xinput API is very trivial. Essentially there is only
one real call there and that's to poll the device. The API is not so
nice though, because xinput was written in such a way that you can add
a controller whenever you want throughout the lifetime of the game.
The also 'nice' thing is that when you plug in a second controller, it
may actually become the 'first' controller (there is no guarantee) and
the first would become the second. A correct implementation would
're-probe' for joysticks every 'poll' command :(
