@bucanero

Hi, is there any plans for developing save game tools for MGSV TPP PS3/PS4 as in the case of PS3 when i decrypt the save, apply cheats and then encrypt it back using Bruteforce returns error when loading the save in game. i don't know much about this but i came across a thread on reddit saying that it has something to do with like Blowfish software and/or that the save has additional encryption layer.

Lastly the Save Wizard team and someone from X360 scene cracked the save file on PS4 and x360 respectively.

Thanks.

Metal Gear Solid 5 save-games have a custom encryption layer. It has been reversed for some platforms (like PC or Xbox I think) but not for the PS3 or PS4 (as far as I know).

Yes, the SaveWizard tool might have cracked it but that information is not public or shared, so it remains private. If someone wants to reverse and crack the ps3/ps4 encryption and share the info, then great, I can add it later to Apollo. If not, I won't be able to support that game.

Ok i understand, but there's a Japanese site which hosted Bruteforce savepatch like code and I'm leaving here with a link to it

Think you can do something of it? I'm going to close the issue and thanks again. Staysafe.

Hi again, I'm leaving the Japanese save editor online link to you and a save game to you. Hope you can manage to figure something out.
