I hate it when a PC game includes a disc that you need to have in to Play it. It's just kind of annoying and you need to make sure the disc doesn't get scratched. Plus, if you pirate a game, sometimes you can't play it because the rip doesn't allow you to use the unmounted ISO to play. Apparently
Game Copy World has the solution in the form of No CD cracks and EXE fixes for games you "legally" own. Neat concept, anyway. I assume all the files work, i've already tried several of them. If yours don't work, you're using the wrong version of the patch/file.
