Hey Snaake! The button mapping is actually in small print on the back of the board. K11 and K12 are the buttons when you push in the analog stick. For reference though, the buttons from left to right are: Triangle, Circle, X, Square, L2, R2, L1, R1, Select, Start, Left Analog button, Right Analog button. The joystick inputs on the top are in order of Up, Down, Right, Left.
