Place the Game Boy Player flat on a surface, with the top surface that would mate with the Gamecube facing up, Nintendo logo on the bottom.

Use a gamebit screwdriver to loosen and remove eight screws around the top of the surface.

After the screws are removed the top piece can be lifted off of the rest of the unit.

Try grabbing around the raised portion where the socket would mate with the bottom of the Gamecube, and and lift straight up and out.

Use a Phillips head screwdriver to remove 11 screws installed all around the metal heat sink.

The metal shielding around the socket port is a separate smaller piece and should be removed first by grabbing around it and pulling up and away.

Then, the rest of the outer shielding can be pulled up and away.

With the metal shielding removed, the motherboard can be lifted up and away from the bottom shell of the Game Boy Player.

The shell has another layer of shielding in the track of the motherboard, and this can be pulled up and away after removing the motherboard.

Additional removable pieces include:

two poles, one on the side and another near the corner,

a small flat piece near the front above the cartridge slot that would mask over the extension port,

and a long thin piece that goes across the shell, attached by a spring, which overall act as the cartridge's ejector.
