I'm sure the calibration screen could be made a lot simpler by actually monitoring what's going on and asking the user to do stuff like move the left analogue stick to all extremes, then move the right to all extremes... I was just being lazy with that screen really so you have to watch and see what moves yourself.
I doubt it would be that hard to create a universal mapping thing! Just need to automate what I've got a bit more.
