I assume your talking about the screen cover? The classic game store near me sells replacement screen covers for really cheap. If you have one near you it's worth a look. Otherwise eBay has them. It's as simple as peeling off the old screen cover(with a dull pocket knife or something similar), peeling the paper off the adhesive back of the new cover and pressing it in place. Just make sure you don't get dust, fingerprints, etc... on the actual screen while the cover is off. Couldn't be simpler.
