afaik, there's nothing you can do if the legit keystone isn't included. a lot of content sites will mention if it is included.
It's a DUPLEX release and I dont find any information about it using a proper keystone, so I dont think thats it.
So I did some more testing with interesting results:
- I uninstalled the FPKG version from my PS4 #1 (where the save is coming from), then I reinstalled the game from a legit disc (same CUSA though). Then launched the game - and the save works! So it does not matter if I use FPKG or legit disc - both loads the save fine.
- So I made another manual save, ran PS4 Save Mounter, mounted the save, saved it to PC. Then plugged in PS4 #2 again, ran PS4 Save mounter, mounted save and copied from PC to PS4. Restarted PS4, started the game, loaded save. Corrupted.
I wonder what this means? One thing I could say is that my PS4 #1 is not activated with PSN or with the activator, so it uses a different PSN ID compared to PS4 #2, but I dont think that should matter?
Maybe there's a problem with my FTP software, WinSCP...
