Was going to take my wii somewhere to be modded today but I couldn't get the wii case open. I have a triwing screwdriver, and it worked fine for the first 7 or 8 screws, but there are a couple that will not budge. The triwing screwdriver just spins around, not twisting the screw at all. Tried using a 1/16 drillbit to get it out but it didn't work either. I have about 20 small screw drivers and none of them will work. How can I get those screws out of there? I've tried about everything.
