Opening Gamecube Controllers

[Porksta]

I wanted to open my Gamecube controller, because a button was sticky, but when I went to unscrew it I saw that it used three pointed screws. Do stores sell this type of screwdriver, or will I need to order it? Or is there something else I can use?

What you want is a tri-wing screwdriver, import and modchip outlets sell them online for taking apart Nintendo stuff (GBA, Wii, etc.)

In a pinch, you can try using a jewelers or otherwise small and fine flathead screwdriver. Try to find one with a blade that fits and bridges between two of the three slots, and avoid stripping the screw heads.
