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
