Def Jam: Ffny Savegame Hacking
« on: September 25, 2004, 11:27:00 AM »
Is this the tutorial people used to find out the SigKeys and AuthKeys to add to Xbox-Saves Manager's resign.ini?
CODE
Title:   Generic Reversing of Hacked Save Game checks.

Author:  [SHEEP]

Level:   Intermediate

Target:  VEXX

Tools:   IDA..      (http://www.google.com)
        cxbx       (http://www.caustik.com/)
        Xbox Flirt (http://www.geocities.com/smil0r26/misc/xflirt.zip)
                    place the xflirt sig file into the SIG folder in IDA.


If it is, is there an alternate way, because of the 3 tools (IDA.., cxbx, and Xbox Flirt) required, I only have cxbx?

I edited the amount of Dev Points my character has for Def Jam: Fight for NY, but ofcourse it doesn't load afterwards.

Thanks for any help.

I used xbedump on DJFFNY's default.xbe, and found that its SigKey is C9D8E3AF6D5647969197DACD669187DB.

I still need to know where to get the following values to make a complete entry in Xbox Saves Manager's resign.ini, though:
AuthKey
DataOffset
SigOffset
LenType

If you have any information that might help, please reply.

Thanks.

Really interesting! I wouldn't know how to help you though, sorry. But it's cool to see you found a way how to edit the dev. points!

The values for money and dev points are right near the beginning of your character's file. Their bytes are in reverse order so 0x4D2 (or 1234 in base 10) would show up as D2 04.

But like I said, there's no use changing it unless you can re-sign the save file. We still need the AuthKey and the other info, or at least the knowledge on how to find them for ourselves.

You lost me there wink.gif. But if you are able to find it and change it, I don't see why you should resign the save. It isn't locked to your Xbox right?

Why can't Savegame hacking be just as easy as opening the file with a Hex-editor and just change the numers sad.gif.

I used xbedump on the default.xbe from DOAXBV and searched the output for the SigKey given for it in resign.ini. I found a match where it says "Signature Key." I just looked at the same place in the dumped info for DJFFNY to get its SigKey.

You missed the point. There is no entry for Def Jam: FFNY in the resign.ini. The purpose of this thread was to get the information needed so that I can make an entry for this game in the resign.ini.

So where do you actually get all these tools now. A lot of sites containing em have faded away.

The tutorial and tools I mentioned in the first post refer to hacking a game's default.xbe to remove game save validation versus what I am trying to do (create a valid save). I didn't know this then.

But, who knows. Maybe that tutorial also has hints on where to find the AuthKey.

Yeah, those sites are gone, and it seems that the people who have the knowledge on how to validate hacked saves are keeping it to themselves...probably for fear of abuse with regards to Xbox Live.

Why don't you just use Briens tool to set the resign key to a set one?

See this thread for more info smile.gif

Close.  ;)

You will still have to resign a save, yet with that program the AuthKey will always be the same for any game you patch it with.  I suggest you download it and read the readme file for a full explanation.  ;)
