    Re: Max Payne 3 Modding

    Well, i'm trying to get the Algo and Key, i have disassembled it but its hard to go trough a 30MB File to locate the right Spot, there is so many Crap... ;)

    What i know so far is that the Secureblock consist of 3-4 Parts saved together, Progression, MPStats, Avatar?, PlayerCustom, they are saved separately each after the other, so i'm at the Spot where they are saved, but still not at the Spot where they are actually encrypted.... So i try to locate the first CRc found now and will then go further from that Spot, perhaps its better... lol

    Also there is a possiblity that they saved it as XML but i'm not 100% sure its more an Intuition from Stuff i have seen... Well, if nobody else get it first, i don't think an SE is goind to be made so fast... Anyway what sucks the most is the NYM Hardcore which must be completed in ONE SITTING WITHOUT die once, almost impossible with all the Bugs that causes Death for no reason, and even if a SE is made it probably not help here... :(

    These aren't my saves but you guys wanted saves. There's also a lvl 50 gpd in there, but I think you have to be the lowest rank for it to work like GTA4. But yeah there they are.
    I couldn't be assed to look through this thread to see if they've been posted either.

    Re: Max Payne 3 Modding

    The prob is, its still not possible to decrypt the Saves. I invested some Time to figure it out but unfortunately without success.
    So if not someone stumbles over the right Spot and is able to figure it out, there is no way for a Editor anyway.

    Update:

    The Encryption and all Checks are defeated, it took us (me and Philymaster) about 2 Weeks to figure out everything, i'm currently working on some smaller Things and will then release a Tool...

    Only one word about the Security, its one of the worst i ever seen till now, even breaking into Fortknox is easier, really!

    Re: Max Payne 3 Modding

    Update2: ;)

    I added support for PC Saves, but it probably only works for Saves made with the cracked Reloaded Version, because the Saves are tied to the Profile and or PC (i currently investigate this...) and the Reloaded version cracked exactly that part, so a specific 256 Bit Key which is initially used is always the same and not tied.

    All the other parts of the paranoid Encryption (Encrypted 5 x 16 x with 5 different dynamically created 256 Bit Keys) are the exactly same as on the Xbox, so the Tool currently decrypts Xbox and PC(probably Reloaded Version only).

    Also because the final HMAC is valid i at least know the decryption is 100% valid.

    Only Problem, the Savedata is compressed (ughh!) but its the same on XBox and PC, so its probably not a XCompress and i checked its not Zlib, i currently suppose its an proprietary RLE, which i have to investigate and hopefully can rebuild.

    But because the underlying Savedata is 100% the same on PC and XBOX, its possible to import/export the compressed Data and exchange PC<>XBOX even if its still compressed... lol

    The Tool is released as soon the Compression is broken, if not possible (i don't hope!) its released as is and updated later if Compression is broken.

    And well its not 100% sure if it is used, but there is a DevmenuSwitch with a Value for it in the Save .. LOL! .. if this is really used, its gonna be fun once the Compression is done...
