To quote: Hello everyone, i created this little app it took me about 15 minutes.
This app can unlock another persons save by opening your param.sfo from your save and then opening their param.sfo from their save, it will then create a new param.sfo that you can use to overwrite the other param.sfo in the other users save that you'd like to use.
this app may not work for some or most games, but i know it works on raging blast 2 =D
p.s. i used satanicat's save guide as a basis for creating the app
UPDATE: i've added a few error checks to the app
UPDATE 2/8/11: i've added a few tweaks to the UI, also i've made the app copy your gameID from yourSFO to the otherSFO if the id in otherSFO is not the same, hopefully this might help games from other regions work.
UPDATE 2/9/11: i've added a save file dialog, in other words, you shouldnt get any file errors now, you can choose the name and where to save the modded param.sfo also theres a new feature enabling you to copy your console id to the modded param.sfo users can try this if the default settings wont work.
I've just been poking around some of my save dumps. I think this might only work with games that store all of the user data in the SFO file. Most games also have a PARAM.PFD file as well as a separate file for the main save data(which could also store user info).
So, it looks like we're out of luck for more complex saves. Anyone working on a simple decrypter / encrypter so we can hack the save files and get some extra health?
