  • 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.

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

  • 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.
