I've heard everyone go on about the save exploit but no one has told me what it is. Can you explain?

Save Exploit is an old glitch that allowed you to load in weapons and dresses from other save files. It was mainly separated because it was kinda cheesy and it would be patched from the game eventually the only way to run it now is if you had saved a back up of an older version before updating. I've considering removing it as not everyone has easy access to an old version of the game but I didn't want to invalidate the runs of the people who did run it. I'm not sure if I'm allowed to upload an older version to the boards as that would open the gate to piracy
