PS4 can be tricky at times, depending on which CUSA and even version of the game there can be some serious differences in code. Basically if youo don't have the exact same version that the dev had when developing the codes you are sunk.
I'm fully aware of that, these games tested on a matched CUSA and version and they didn't work.
For example Resident Evil 7 tested last (same game version and patch ) didn't work
