Check resetDefaults for bugs and clean/comment (I think there's a small issue in there somewhere that makes the analog stick behave strangely after the board is reset for the first time)

I suspect this should reduce inconsistency issues on at least those buttons on the d-pad.

This is because the way the d-pad itself presses down on the rubber domes likely causes initial contact to be near the outside edge of the pad. In the current orientation, this means you have to press a good deal before the rubber smushes enough to make contact with both pads on the pcb.
