You will only need two tools to take apart the Wii. The first is a small Phillips screw driver, which should be easy to locate. The second tool you will need is a Triwing driver. This type of driver is not very common and might take some phone calls or internet searches to locate. Ours was purchased off of Ebay several months ago to repair a broken Gameboy.
Flip the device upside down and remove the small silver Phillips screw. Once out, remove the battery tray from the console.
Next remove the rubber foot directly above this battery tray. Also remove the three square white stickers from the bottom of the Wii. The rubber foot and the sticker are covering hidden screws. Figure 3 provides a shot of where these screws are located.
Hiding screws under stickers and rubber pads is a common method used by electronics manufactures to help increase the aesthetics of their devices, as well as prevent people from easily locating screws and taking apart their products.
Unscrew the two Triwing screws and three Phillips screws from the bottom of the Wii.
Flip the Wii over onto its right side. Locate and remove the two rear rubber feet and the two rectangle stickers near the faceplate.
Remove the two silver Triwing screws in the holes and remove the two black Triwing screws on the faceplate (Figure 4).
Flip the Wii upright and carefully remove the two socket covers. They come right out with a little wiggling.
Remove the three black Phillips screws from the black plate (Figure 5). Note the one closest to the faceplate is the longest and will need to go back into that hole when putting the Wii back together.
With the screws removed, carefully pull off the faceplate of the front of the Wii. You will need to disconnect the red/black wire plug from the Wii to remove the faceplate completely. Figure 6 shows what is hiding under the faceplate.
Remove black plate from memory/controller socket area. Remove two silver Phillips and two silver Triwing screws from memory/controller socket area (Figure 7). Lay the Wii on left side (with the ATI and Nintendo logo facing you) and slowly work the right side cover of the console off the device. This will take a little bit of force. If something appears to be stuck, double check to ensure you removed all the screws. Locate and remove four screws holding DVD reader in place. Two are located in plain site in the middle of the unit. Two are located near the front of the Wii inside the DVD unit (Figure 8).
Slowly tilt the DVD player upward toward top of Wii. There are two wires that need to be disconnected before you can safely remove the DVD unit. One is a plug type of connector that only requires a little tug. The other is a circuit strip connector that requires you to lift the brown catch, which will release the pressure holding the strip in place (Figure 9). Do not break this!
You can then access the Installation Canvas and proceed with your Wii Modification
