Is it possible to convert a Mad Catz wireless Game Cube controller to a wired one so I can use it on my Wii ?

I'm having a tough time finding replacement Game Cube controllers that don't break inside of a week and I wanted to convert my Mad Catz wireless GC controller to a wired one so I can use it on the Wii.  The RF portion of the controller some broken micro resistors in it, but the rest of the unit is fine.  I need to know what points of the circuit board to solder to mainly.
