I've read that once everything goes down Sept 27, only the PS2 will have the single-player mode available. I already have AotI covered, but I'm looking for a way to play my PC version of PSU Ep.1 entirely offline once this happens.
All the links I've found for an .exe that bypasses Game Guard are broken or archived. =/
Nevermind: Found something in the archives from these very forums. ^^; Now I feel silly. archives/forums/comments.php@DiscussionID=508&page=1.html for anyone else that wants to know.
