Savedata Encryption/Decryption
So I modified SAVADATA.java to ignore fuse stuff. Now encryption should be completely alright.
I need testers.

Thanks. It does seem to be a KIRK (in Java) related issue, since I've also reached the same conclusions (about the hashes).

I got a successful report via DM. So I think this patch can be merged into jpcsp svn tree.
Unfortunately he disables receiving DM.

Sorry. I just sent you a PM regarding this.
Great job! Smile

I reviewed r3473 and the patch was wrong...
Please check https://code.google.com/p/jpcsp/source/detail?r=3473

I noticed that, but I found it odd to be required. Does this make SAVEDATA not compatible with the PSP? If so, then it would explain a few things about the algorithm.
I will change this again to match your patch, but could you please check first if the current SAVEDATA produced by JPCSP is loadable on a PSP? I'm interested on detecting exactly what causes the difference. Thanks!

EDIT: Nevermind. I found out why the order was so important in this case.
I've properly implemented SAVEDATA hashing in r3488. The generated SAVEDATA was tested on a real PSP and confirmed to be working. Thanks! Smile

Thank you so much.

Hello Hykem.
Just wanted to let you know that Key1 is actually the ThreadManForKernel NIDs, that's why you can't find any references to it in the code. Smile

Sorry about the double post, figured out the name for the last function, sceSdCleanList. Big Grin
