PS3 Save Data Checksum?

Post by Kobkob »

Hi, I've HEX editted a Save Data and loaded it up on the game but I've gotten an error saying 'Bad checksum, this file is corrupted'.

That's because I didn't update the checksum value, I know. But I'm still confused, I have a few questions ...

1) Is the checksum algorithm of a PS3's Save Data similar to that of a PS2's Save Data?
2) Still CRC-32? Or different now?
3) Where exactly is this PS3 checksum value? At the very beginning of a file, I'm assuming?

Thanks a lot!

i can't really say much about ps3, but psp saves are encrypted.

i suspect it's the same with ps3.
