/* Controller support header
* Part of PSn00bSDK
* 2019 Lameguy64 / Meido-Tek Productions
*
* Currently only provides a bunch of definitions and a few structs but no
* handling functions yet. See the io/pads example for a simple manual pollling
* implementation (with support for DualShock 2 controllers).
*
* Work in progress, subject to change significantly in future releases.
