your PS4 needs to be hacked in order to get a decrypted and readable save file; copying save data to an USB drive using the PS4 menu isn't enough, and will yield you a save file data that's encrypted for your PSN account.So, I tried to use this on a PS4 save file however the .exe states that the file size is incorrect. My file is 6.12mb whereas your application wants a file exactly 3.2mb. Now I do have 3 slots saved to which may be an issue? I have uploaded my save for you to use to add compatibility potentially?
I am afraid I can't help you much more with that issue as I have zero experience with PS4 scene
