In Step 16, only 3 screws are holding down the Gamecard Slot. Two of the screws that are circled are for the D-Pad daughter board and ARE NOT 5MM LONG!!! Sinking a screw that long into the D-Pad daughterboard may irreparably damage the housing.

Step #15 is incorrect. There are only two motherboard screws. The third screw circled, the right side of the console, is a passthrough for the rear housing screws.
