I have used this toolkit for Wii, Nintendo 64, Gamecube and DS Lite. Others have reported that they had no trouble disassembling the Wii. This set does not cover all the screws needed for the N64: you will need a large hex screwdriver to take the console and controllers apart. N64 Game Cartridge, Gameboy Gamepak and memory card can be fully disassembled with this tool kit alone. Nintendo DS Lite It has everything you need for DS lite. However, I found the instruments far from optimal as the DS is notoriously difficult to use. The screwdrivers were fine, I would only recommend using other alternatives to the pry tools and tweezers provided. The Gamecube kit includes everything you need to disassemble your Gamecube controller. Complete disassembly of the console requires a larger hex screwdriver (be careful with some of the hex screws in the game cube, I nearly snapped some of mine). In general, the screwdrivers work well, except for the Y-shaped bits, which weren't ideal for my set. Additional tools can be used, but I would use something more robust when working on complex tasks. For the price I expected that. Disclaimer - I have not tested T head screwdrivers.
