Assassin's Creed 4 Game Save editor

[Berion]

I even found a starter save that says it has the following stuff, but looking at the main save file I don't see where it has the 500 even. I must be doing something wrong.
Reales at 99,999,999
Max Resources: Sugar, Rum, Cloth, Wood, and Metal each at 500

500 is 01F4, after reverting and putting FF between values, should be 00F4FF01 which You looking for (I'm based on what this tutorial said; in assumption that PS3 save is the same).

Until save isn't decrypted or is encrypted twice (first layer by CellOS, second by game itself).

thanks for the tip @Berion I'm hoping to spend some more time trying to figure this out. I think before i was just looking for F401 probably in the file after I decrypt it with bruteforce

In the assassin's creed games, when you enter in the main menu and select "offline" the game allows to store only 3 gamesaves, are like 3 "slots"
When you create a new game in one of that slots you need to enter a name, lets say you entered "wiziohaj"

Well, that name is the only thing "human readable" inside the savegame, but the savegame is encrypted by default so you cant read it unless you decrypt it

Im mentioning this because is an easy way to see if your tool was able to decrypt it... just open the file in a hexeditor and search for your name (or whatever name you entered when you created the "slot"). If you can find it means you are in the good road
Otherway, if you cant find it, it means the file is still encrypted and is imposible to modify it (dont waste time trying to search for specific values because you are not going to find them)

Until game developer not obfuscate it (XORing, endiannes byte swap (BTW: Sony loves this shit), interleaved by some value, additionally encrypting). But I understand Your point, it is of course good assumption to start from somewhere. Better eye can quickly tell which part is encrypted/compressed/etc. just by looking at hex values. ^^

I mentioned it because yesterday i was decrypting the savegame from assassin's creed revelations and i was taking a look at the decrypted savegame in a hexeditor. That name you enter when you create the save is literally the only thing that can be identifyed easilly, but all the other data is completly unrecognizable, is imposible to deduce how all that data works just by looking at it in a hexeditor

All the assassin's creed games seems to have a menu where you can only create 3 saves (thats retarded btw, it makes me remember to the gameboy cartridges that was storing the savegame in the cartridge eeprom), my bet is all the assasin's creed games published for PS3 uses the same savegame format and procedures
