I just used a phillips screwdriver, with a point that got small enough to fit in the middle of the triwing screw. It had a reinforced tip. You can tell its reinforced because it has a small change in color at the tip. But heres how to do it:



Works great and doesnt mess up the screw, console, or screwdriver!

EDIT: picture of screwdriver

Has anyone tried this yet?

i've tried it with flat screw driver, works for me.. but the screws for gameboy sp "SCREEN" are smaller..but yeah works.although tri-wing screws are only a few bucks, worth if your always working around nintendo products..
