Games can use the OUYA controller buttons however they wish, but we recommend the mappings below for the O, U, Y, and A buttons. If you are running a stock Android application that is not OUYA-aware, this is also how the buttons will be mapped to the standard Android navigation buttons on the navigation bar for a typical device.
OUYA Color Default Function
O green select
U blue options (Android's menu function)
Y yellow -
A red back/cancel
Please use the naming conventions below when referring to the controller buttons in help screens for your game:
O, U, Y, A
System (the home button)
D-Pad
LS (the left joystick movement)
L1 (the left bumper)
L2 (the left trigger)
L3 (the button function of pressing the left joystick straight down)
