You can adjust this if you want to.
Gamepad Buttons
---------------
The `buttons` struct member is a bitmap,
each bit mapping to one of the 12 buttons reported through HID.
Here's what each bit means:
* 0: Blue
* 1: Green
* 2: Red
* 3: Yellow
* 4: Orange
* 5: Tilt Switch / 2x kick
* 6: Solo modifier (second row of buttons on guitar)
* 7: ?
* 8: Minus
* 9: Plus
* 10: Drum pad modifier?
* 11: Cymbal modifier?
* 12: ?
hatAndConstant
--------------
I don't get this, but here's what the values mean:
* 2: right
* 6: left
* 0: up
* 4: down
* 8: nothing
