Hi, a dude has done some investigation and found something interesting that i think the devs here should look into:Sponsored Links
He has uploaded the save files: [Register or Login to view links]Originally Posted by stadiconI am a PES and NBA 2K modder for PC. Last few weeks i did a research conserning the possibilities of Game Saves editing on PS3 and i tried to find a way to read the Option File of PES 2009 comparing the PC save and the PS3 one. So, i came accross some interested clues:
1) The size of PC and PS3 save file is identical (kind of).
2) Through the simple process of editing (in-game), saving and comparing i found out that OF of PS3 is almost identical to the one on PC but encrypted. For instance, every time i change a player's data, an 128-bit section changes in the PS3 save file. This section, is in the same position of the file, as the position of this player data on the PC save!
So here is my though:
If we have a default Option File for PES 2009 (didn't test for 2010, yet) we can be almost sure it will be identical to the default on PC (which is unencrypted). So, knowing the original data and the final encrypted data, and having the ability to change a byte of the original data and compare the change on the encrypted, is it possible to find the encryption method and the key?
I know, it's not easy. But there is a possibility here: the enryption block is just 128-bit size. So, that means we can compare many 16-byte blocks to each other and we can focus on decrypting just 16-bytes, instead of the whole file! We know 16 original bytes and the 16 encrypted bytes. If we find the method for those 16 bytes, we can do it for all the file and maybe we find the method for many other game saves of PS3!
So, anyone who knows about encryption and stuff, could help about this subject?
