I took the board of a wired Gamecube controller, wired it directly to an 8bitdo Gbros adapter, and crammed it all into the shell of a Wavebird. I present the Davebird. It was a pretty easy mod, lots of room inside the wavebird. Had to make my own button or two though. Dual rumble motors. Had these two in a parts drawer. Fit pretty nicely in the handles. After a fair bit of sanding all the way up to 3,000 grit... looks like it belongs, eh?
