More Buttons in GPIO RPi2

[tiago-viana-de-oliveira]

Hello everybody, first apologize for my English, I am Brazilian. I would like to use the GPIO of RPi2, but at the standard manual and default configuration is: Directional, Start, Select, A, B, X, Y, L and R, I would like to have the L2 and R2 to Playstation games, anyone can help me. May not be necessary for most games, what do you think?
