    After some researching I came accross hex editting and con resigning save games. So,...in good faith I transfered my savegame to my desktop through the X360 Neighbourhood.

    Now that the game save is sitting on my desktop I decided to have a look at it in Hex Workshop. And to my surprise not much is shown. It looks likes it is scrambled. On the internet I saw a COD5 gamesave with editable strings...??? E.g.: run_faster=0

    Do I need to decrypt the save game somehow in order for me to see the ingame settings/values I can change?

    I need some help how to do this. I discovered that the game save has a small bin file in it (also scrambled) using wxpirs, which is a 1/10 of the size of the total save game.

    well please tell me your looking through the same games saves? the 360dev and 360retail sign saves the same way just with different keypairs so a save on a retail machine will look the same as a dev.

    I dont understand what your meaning tho about scrambled? its not like hex is supposed to tell you in english what its doing lol.

    Thanks 7force, I'll look into it.

    Dark, how do you decrypt these files? Is there any tool for it? The link 7force send did not work :-(.

    a good place to start would be making sure both saves are from the same game. Extracting the save file from container using wxpirs, as it will simplify it for you. Gamesaves have are different from game to game, taking a bit of work to figure what exactly you are looking at.

    EazyB is correct. Most games use a different way of storing their information depending on how secure the information needs to be. Some games may even have an additional layer of encryption beyond the key pair method mentioned earlier.

    For the most part, the game knows that 'x' value is stored at 'x' location in the save, so it doesn't need "thisvalue=" to get the value, it just goes to its address. This way of storing data was especially prominent in earlier systems that had limited space to save to. From my experience, games that store data in a "variablename=data" format (key/value pair) are PC ports that are using an INI as save file.

    The best way to figure out what the save does is trial and error.

    Call of Duty 5 saves are not encrypted. What you are probably stating at would be the container that encloses the actual save. The real save begins at 0xD000 in the container, so start from there.

    You can extract the actual save using wxPirs if I am correct.

    Hi, I did, but then I see a scrambled .bin file. At this stage I can't discover anything that is readable :-(
