So I went shopping at a garage sale a few weeks ago, and Harry Potter and the Order of Phoenix hit game. It was not in its original box, only one case of friction, however, seemed so scratched that I bought. When I have to play home happy, too, asked me the serial number. Of course, without the principal or manual that I can not find the serial number. Is it possible to find the disk?
