There are a total of 8 screws that will need to be removed for this project. 6 external and 2 internal.

Use your #1 screwdriver to remove the 6 external screws and remove the back plate of the controller.

Remove the 2 internal screws and remove the controller board.

Remove the 3 rubber pads and all the buttons from the front controller cover and controller board and set them off to the side for now.

I put the 8 screws in a container with enough rubbing alcohol to submerge them. This removes years of dirt and they come out looking like new. This is completely optional.
