I get to practice on mine, so I don't screw yours up?
Yeah, you'll need the bit. There's a way to melt a pen to get the screws out, but it's always better to have the actual tool to take it apart.
I had to buy a Tri-Wing driver for my Wii chip. I'd rather have it though, than to try to gets the screws out some other way, and end up stripping them out.
