So, after obtaining the titular game, I found its data is contained in one file called "ps4data_body.bin", which is a little over 600MB in size. I'd like to know if there's a script or tool that could crack this baby open? Sadly, the few resources I tried failed to get the job done. Anyway, got the archive in question right here:

ps4data_body.bin

Are there any other files with similar name? This file seem to contain only raw data and you'll need a directory file containing offsets and size fields to unpack it.

Sorry for the late response! Anyway, I checked, and.... perhaps this is the necessary file?

No idea. But it's using the same structure as the previous one:
Code:
char   Signature[4] // "mdf\x00"
long   UnzipSize // Probably?
byte   Data[?] // No fields about the actual size

Even if you manually cut off a piece of data based on the signature and scan the compression with comtype scaner, you can't actually find a match.
So chances are that the data are encrypted after the compression is performed, which can explain why there's only one mdf signature in this file, if it indeed is the only file recording all the necessary info.
