I was just doing random searches regarding PS3 save game editing and came across an interesting discussion that got me thinking.

Hi, I've HEX editted a Save Data (SAVEGAME.SVG) 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!
That was away back in
20 Nov 2009 @ 10:44 on the AfterDawn forums and it got me wondering. We now have the Xploder game save resigner.. soooo.. anyone guess my idea/question? Would it be possible to HexEdit a game save and then use the Xploder to resign it?
The thread I was reading (Serane's thread) states that once the save game is edited there was an error saying 'Bad checksum, this file is corrupted' well back then there wasn't the Xploder.. would it be possible to HexEdit a game save and THEN use the Xploder to repair its checksum?
Has this been thought of? Anyone tried it?
