Yeah, oddly enough only early versions of Photoshop can fix screenshots taken with PrintScreen, such as Version 4 or 5. There isn't a good way to do so with Versions 5+. You'll have to find some sort of older program (I use Lview Pro 2.0) that can directly import a new 256 color image by pasting it, as the newer versions of everything consider it a high-color image which results in losing the majority of the color information because 90% of the color indexes are black.

You're probably better off finding a Game Screenshot-type program.
