I hereby proudly present you with great news for you and your PS3 console.
I've cracked the extra security layer for Dead Island: Riptide saves! This means good-bye to Game Genie, and you will be able to mod PS3 saves as much as you want to, for free!
Feel free to read my research [broken link to ps3hax.net removed]!
This is a major accomplishment for me, since I've for the first time done any PS3 reverse engineering. I've learned quite a bit in just one week! :)
When will the next release be?
Hopefully soon (within days). I've already implemented this, but I'm facing another critical problem. You can read more [broken link removed] technical details about this issue on CyaSSL's community forum.
Rough explanation of the security layer
The game uses a custom tamper protection in addition to encryption. While we could decrypt, mod and encrypt saves, the game just wouldn't load them. The reason is that the game keeps a hash of the saved file, and it's apparently a custom or an uncommon algorithm. This hash is verified by the game, so until now it could always know if the hash of the saved file wasn't exactly what it was supposed to be (then reject the save).
This screenshot doesn't show everything, but what you see here is is a hint of victory. On the left, the PARAM.SFO file is for one saved profile is loaded in a hex editor, and shows the hash that was generated by the game. On the right is my code, and a console program showing my own generated hash, and they are identical!
Now that we can generate this hash, we can trick the game into believing that modded files are clean! :)
