Savedata Encryption/Decryption

[popsdeco]

Thank you so much... But as I said before I don't have test environment of jpcsp.
Do savedatas from r3436 are working on real PSP?

Unfortunately I couldn't test the changes with a real PSP (I currently don't have mine available). But I did compare the hashing algorithm with PPSSPP and the results appear identical (using the same SHA-1 seed, otherwise the results would always be random).

Oh oh oh... Should I switch sce functions to this?

Though it seems I still use savedata side functions from jpcsp :p
