AFAIK, if you have the original, legally you're entitled to install it on your hard drive, as long as you don't part with the original material or e-mail the whdload installed version out, rather just use whdload as intended, and install stubborn games to HD for convenience. I've registered WHDload for this puropse, and can't say enough about it. I've put games on HD that I never thought would be able to be compatable short of a UAE install and ADF rip, though with the age of some of the games, and the storage in question, I'd systematically install everything you can get your hands on before bitrot sets in.
