  • Wii disassembled

    After a week of trying, I finally got my hands on a Nintendo Wii. After taking it for a test drive, I began the painstaking and somewhat frustrating disassembly process. Come along as we go inside the Wii and see the hardware that makes Nintendo's console tick.

  • Wii system battery cover

    I started by removing the Wii's system battery. This would be the first on many,. many screws.

    Next I moved to the black cover that surrounds the GameCube controller and memory card ports.

  • Removing the GameCube connector cover

    Three small Phillips screws hold the Wii's black GameCube controller and memory card port cover.

  • Triwing screws

    After removing the black GameCube port cover, I hit my first roadblock--triwing screws. Some argue that triwing screws make the manufacturing process easier, but these annoying fasteners are also designed to discourage people from doing exactly what I'm about to do--take this thing apart. Nintendo also uses triwing screws on the GameBoy Advance, GameBoy Advance SP, GameBoy Color, Nintendo DS, and GameCube controllers.

  • Triwing screwdriver

    You'll need a

  • Mix of Phillips and triwing screws

    Once you remove the black GameCube port cover, you'll find a mix of triwing and Phillips screws that should be removed.

  • Wii motherboard - GameCube controller and memory card ports

  • Wii motherboard - Underside

  • Samsung NAND flash memory
