I took a dummy save of GTA5, and i modded Franklin money with game genie.

I decrypted the two RAGE.SAV files (before and after modded) with bruteforce.

I made a hex compare on the two files to see what it changed.

And here is offset that changed between the two files:

- offset 0026DD0:
2E F3 D6 C0 AE F1 D8 D0 52 68 43 81 19 EF 6F C8 (before modded)
DB 46 CC 1C E7 10 A9 FB 99 C3 FD 13 90 26 85 55 (after modded)

- offset 0042140:
E7 3B 38 75 5D 41 CE FC 8F 31 84 9D 98 A9 BD 4D (before modded)
2E D8 8C 68 4D 49 05 3E 42 2C 12 0E 13 FA 63 B4 (after modded)

All other offset are same between the 2 files but not these two above.

I think the first offset is for Franklin money and the second offset is a checksum about an AES encryption.


When i modded Michael or Trevor money with game genie, that was the offset 0025D40 and 0028100 that was changed between the 2 files.


Someone have a clue or can have a solution to modded or decrypt GTA5 savedata?

You can make the same test as me, only these offset changed between the two files.

I think it can be easy to decrypt or mod when we know all that, but i'm a noob on decrypt savefile lol

But we have great modder here! they can i think, game genie already did it!

start off by comparing several saves of say frank from two or three ppl with your own and take the amount of money before hand then either earn or lose money and recompare , otherwise you will never know what you asked
