Savedata Encryption/Decryption

[Hykem]

no i deleted all my saves, then enabled the option, if i download a P3P save from the internet i can load it fine but when i try to save i get the mentioned errors and a dialog box :
Game data has not been saved
Abort save? Yes / No

I also get a 0 KB savefile on the slot i try to save to.

Hmm...
That's really odd, since, as you can see, in this line:

Code:

at jpcsp.crypto.CryptoEngine.DecryptSavedata(CryptoEngine.java:1806)

DecryptSavedata is being called, so I'm guessing the game you're trying to save with, is attempting to load the data first, and only then is going to save.
This is common in recent games (6.00 firmware and up) that use multi call save modes.

Again, this can be seen in the following line:

Code:

at jpcsp.HLE.kernel.types.SceUtilitySavedataParam.singleRead(SceUtilitySavedataParam.java:373)

Looks like this game is using SceUtilitySavedataParam.singleRead which belongs to SAVEDATA MODE 15.

Could you please list some of the games you've tried testing this feature with? There's a good chance that it may be an additional protection mechanism or an additional checking layer.
Thanks!
