Arduino Uno Game Controller Converters

[xxninjabunnyxx]

I would like to know where to start in programming video game converters. My idea is to take the data sent from the serial data controller, decode it, rearrange it, and the output it to the system. I would like to start with a gamecube to wii classic controller converter, the gamecube controller is a lot easier to hold in my hands than the classic controller and you can only play some games with the wii classic controller. I would like to know where to start with the code. Thanks in advance!
