Does anyone know if a standard first player Famicom controller is the same size as a NES standard controller? I want to order a Famicom controller and either a) insert the circuit board guts of a NES controller into a Famicom controller's plastic case or b) solder a NES controller's cable onto the Famicom controller's circuit board. I've done the latter operation successfully with a Japanese Hudson joycard with an similar North American controller's cable. Hopefully the NES and Famicom controllers are the same size with the same circuit boards (excluding the microphoned controller 2), making the operation easy.

Your thoughts?
