The whole point of CFW save editing is theres no need to edit any files when hacking a game save you just replace the required files with the ones you want minus the ones that store any form of psn or console ID
you can hack locked or unlocked save files without the need of hacking on CFW using either comgenie or FTP programs (source I own a cfw ps3 and have done this myself many times, so allow n00b comments if you have no idea what you're talking about)
And on OFW on the majority of games you will receive a "save corrupt" message using this program hence rendering it useless. Only answer to a reply if you are clued up on the scene otherwise don't bother
