View Full Version : Trying to figure out how to mod Assassin's Creed 3's GPD without JTag!
Hey guys, I found out that it is 100% possible to modify Assassin's Creed 3's 555308AE.gpd File. In the GPD you are able to see your achievements which are unlocked and even the PREORDER UNLOCKABLES I just cant find them :P. So I'm trying to find them, and the best way IMO to narrow down the location of where the unlockables are in HEX has to be getting your GPD before redeeming a Pre-Order code, then after redeeming a code, get the GPD and find the changes. So if someone could help me out in figuring this out I would be glad. I found this GPD (http://www.mediafire.com/?w8h9pa5ozf6dlmr) on 360Iso which has EVERY Pre-Order bonus, so it would be good to use it as reference to your own GPD!

This sounds like a good idea. But couldn't we also get pre-order content by modifying the save?
At any rate, I totally second this. Unfortunately, I've already redeemed my codes.

Hey I could help you with this if you want. I was thinking on working on AC3. Since Halo 4 is already modded.

I am going to bed. But open 555308AE.gpd in exprofile editor or what ever and look at setting 2 they add a whole bunch of stuff in there. I tryed to add it to mine but it froze so maybe some checks or changes in the first settings file. I'll work more tomorrow!

It would help a lot if some one has their profile GPD before and after redeeming the codes. Any one of the codes. Just one with and one without to see a hex comparison.
Damn anyone figure anything out?
Does anybody mind spending a small amount of money for education lol. Ebay has codes so I guess that would be a start.
K guys! I got a Mayan Ruins code and I am currently analyzing both of them in Hex, its just that there is a lot :S

Hey, Zaid could you link me your GPD after and before you entered the code? You should also try comparing it to the one with everything unlocked

I got this for setting 2
10387
I got this for setting 1
10386
I am not sure what happens in setting 1 but in setting two it's pretty obvious. so the dlc codes get added in setting 2 if I am correct. They are flagged in the first one? But it's too vague to take all the codes away and compare them to a different persons GPD with all the codes. So thats a stretch!
Alright, If anyone needs both GPDs for comparison, just ask! Also, this would make it much easier, but if someone were buyingthis (http://www.ebay.com/itm/Assassins-Creed-3-Sharpshooter-Multiplayer-Character-DLC-Code-Card-Xbox-360-/251189063225?pt=LH_DefaultDomain_0&hash=item3a7c08ee39) It would also help as comparison. I think I may buy another DLC because If I already have 2 GPDs, then another one would be perfect for comparison!

These are the changes for 1 DLC i'ill update which in a sec
Setting 1
Offset:228 | 2B5A(this may be any number) - 3359
offset:523 | 01053039F9E6FE120005FCC50C6BC7160105BFD110D0C304(t his may be any number on the left.) - 01053039F9E6FE040105FCC50C6BC7120005BFD110D0C316
Setting 2
Nothing Changed!
New Data:
33 59
04 01 05 FC C5 0C 6B C7 12 00 05 BF D1 10 D0 C3 16
When I put the disc in it froze the first time but the second time it worked fine but no DLC. I am guessing they have a check...
Yes... They have a check but fortunately we know what it resets. :)
It took my modded 33 59 data and changed it to 02 06
It took my modded 01053039F9E6FE040105FCC50C6BC7120005BFD110D0C316 and changed it to 0005FCC50C6BC7120005BFD110D0C31200
I am not exactly sure what is going on here but I am guessing it is reseting the mod somehow.

What is this setting 1 and setting 2? Also, you are going to have to MOD your own GPD, that is my GPD so Im guessing thats why it wont work for you
