Nintendo Screw Driver

I made another bit to open Nintendo carts with. All you need is an old thin straight slot screw driver bit and the use of a Dremel or other rotary tool with a cutting blade. Cut a gouge into center of the bit about 1/8th an inch. Then working from the center out slowly cut away the center. Eventually the bit will open enough to wrap around the screw. Sometimes though the bit is too thick to fit into the tiny grooves of the screw. If this is the case sharpen the points until they do fit.

What will I do with the extra bit? Probably throw it away. Oh well.
