I just can't unscrew the damn screw! I have a N3DS and the left screw is okay, however, I have used all my screwdrivers and knifes and I can't unscrew the right one. I want to take out my SD card, but the cover is stuck because of the screw. Any suggestion? I'm so upset with nintendo because it made the N3DS SD Card location in a stupid place, and also, with myself because I was so stupid to mess up with the screw. If you guys know a way to unscrew a ruined screw I'd appreciate. Thanks.
