Things You'll Need
Instructions
Remove the six screws on the bottom of your Super Nintendo system with a 4.5mm Gamebit screwdriver. There will be one near each corner, and two near the bottom corners of the bar code.
Set your SNES on a hard, flat surface, right side up, then pull the case apart by hand.
Pull up on the right side of the rail that holds the "Reset" and "Power" buttons, then pull out the metal bar on the end of it. Once the metal bar is removed, pull the rail out of the casing entirely. Make sure not to lose the spring on the left-hand side; it may shoot out of the case when your remove the rail.
Unplug the white ribbon cable connecting the controller ports to the main board.
Press down on the gray tabs on top of the controller ports to disengage them, then pull them out of the case.
Follow these directions in reverse for installation.
