    • Remove the six 13.25mm Phillips screws on the bottom of the game console with a #2.5 flathead screwdriver.

    • The screws are recessed about 40 mm.

    • Flip the game console right side up and take off the top by pulling it up and away from the rest of the device with your hands.

    • Note: Underneath the cartridge tray is a black trapezoid-shaped tab/lip (see marker). When properly assembled this tab/lip goes below the motherboard and shielding as seen here.

    • During reassembly, make sure you orient this tab underneath the motherboard in addition to orienting the tray on top. Failure to do so will bow the cartridge tray and place stress on the component, causing the cartridge spring mechanism to bind.

    • Remove the three 13.25mm Phillips screws that secure the motherboard to the lower case with a Phillips head #2 screwdriver.

    • Pull the motherboard assembly straight up and out of the plastic case with your hands.

    • Turn the motherboard assembly over so the metal cover is facing you.

    • Disconnect the wire harnesses from the motherboard assembly:

    • Player 1

    • Player 2

    • Power

    • Make sure you remember where player 1 and player 2 cables are plugged in; do not mix them up. A good technique would be to write each title on a piece of tape and wrap them around the appropriate wire.

    • Lift off the EMI shield (metal cover) from the motherboard assembly.
