Merge base PS4 fpkg with update fpkg (to cut down on space requirement)
This is for when you already have the base fpkg and the update fpkg for the game and the update is taking up a lot of space and you want to merge it with the base fpkg.
You will need Fake PKG Generator (the version doesn't matter, we only need to use 3 components) https://github.com/CyB1K/PS4-Fake-PKG-Tools-3.87/releases/latest
1. Extract both base and update fpkgs into their own folder using orbis-pub-chk.exe, call the folders whatever as long as you know which one is which.
2. Cut/copy all the contents of the update folder into the base folder and overwrite whatever you get prompted to overwrite.
3. This is where you need to get the naming convention for the merged game folder correct, name the folder according to what the Fake PKG Generator documentation says (not going to repeat it here unnecessarily).
4. Now you open gengp4_app.exe and locate the param.sfo which should be in the /sce_sys/ folder and hit "Generate GP4" and then do "Save GP4" so the gp4 file actually gets created.
5. Final step, you open orbis-pub-gen.exe and locate the gp4 file and then it should build the pkg from the merged folder, and then you just install the created pkg file as usual.
