If u do go the route of making a backup, u in luck. Jedi Outcast has no protection whatsoever. I did a straight copy of it with nero. Before u use a patch it usually has to be unaced with winace (
www.winace.com). Once the patch has been extracted from the .ace file just copy it into your game directory. It should come up with a prompt telling u that a file with the same filename exsists, do u want to replace it. Just click Yes.
