User guide

Extracted game (for repacks, skip this if its a dump):

Extract all files from base or update using orbis-pub.chk.exe.
After extracting rename the folder from Image0 to CUSAXXXXX-app or CUSAXXXXX-patch, accordingly.
Move the files from the folder "Sc0" to "CUSAXXXXX-app\sce_sys" or "CUSAXXXXX-patch\sce_sys" and delete the "Sc0" folder after.
Continue the instructions the same as a dump.

Dumped base game:

Generate gp4 project file with geng4_app.exe from CUSAXXXXX-app of your dump and save it.
Open in orbis-pub-gen.exe that saved *.gp4 file and build pkg.

Dumped update game:

Generate gp4 project file with geng4_patch.exe from CUSAXXXXX-patch of your dump and save it.
Open in orbis-pub-gen.exe that saved *.gp4 file.
Make sure that you have selected base game pkg in Command > Project Settings > Patch Tab > "Application Package" field.
Build pkg.

Always backup param.sfo from "sce_sys" before generating a gp4 in case of corruption.

XXXXX - Stands for the CUSA of the game you are packing.

v7.0

Patched the minimum firmware check so pkgs will not longer show as requiring 7.50 anymore. It should show as 5.05!

v6.0

Keystone will no longer be removed from the project when trying to rebuild a base pkg after a finished pkg or after an error on the same project, let me know if you find any issue with it.

v5.0

Thanks Illusion0002 for this patch on cmd, ported it to pub-gen too. Illusion tested it with red dead redemption 2 and it was working normally with a 120gb PKG. I dont know if this might cause any mounting issues so build PKGs bigger than 100gb at your own risk!
