You can download the HWID swapper, and my 100% save file here: I've decided to call it a Hardware ID (HWID for short).
I reversed how the game was determining this, and found out it's using a signature on the save file to tie savedata.bin to a specific computer/user/whatever the hell it is. I was proud of it up until I tried to give it to someone, and they said that RE6 displayed a 'corrupted save file'. This is my 100% save file I've been working on.
