Things You'll Need
Instructions
Turn off the Super Nintendo, and unplug the controller from the console.
Place the controller face-down on a flat surface.
Insert the philips-head into the screw slots, and turn counterclockwise until they come out. Don't press too hard and turn, or you will strip the screws. There are five screws holding the two halves of the controller together. Place the screws in a safe location.
Lift the back of the controller away, and set it aside.
Unhook the rubber wire from around the support posts, and gently lift the main circuit board free. Avoid touching the contacts.
