I have a virtual boy and I tried to open the security screws with my bit, but four of the screws are so deep that it would not reach. when the bit i have didn't work, i tried using a rotary tool to cut out a notch on a standard screwdriver. that worked okay on the shallow screws, but unfortunately it is too hard to line up properly on the deep screws inside the virtual boy. then i tried melting a piece of plastic to mold the screws like i read online, but that just smelled badly and didn't get into the deep holes. i won't say where i ordered, but i ordered a different bit online and unfortunately what i received was too short to fit into the deepest holes. it wasn't until i ordered this tool that i found a way to get all the screws out the virtual boy. i would like to finally say thanks, it worked.
