Is it easy to hack a gamecube PCB?

I spent a good long while trying to find some info on google, but it seems to evade me. Is it possible to hack a good ol’ regular Gamecube PCB to use for a joystick? If possible, a link would be sincerely appreciated, thank you!

Check out the tech talk forum sub forum. Particularly the pad-hacking thread. You’ll find a link in the sticky.
