    • 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.

    • 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.
