This is intended to be used on ps5 where dlc fpkgs dont work. It automatically patches the eboot (or other executables) to use custom prx which replaces calls to the libSceAppContent library to load dlcs from the base pkg.
Developer say :
"
I updated the dlc patcher, its now standalone, fast, and automatically extracts and uses the real entitlement keys from the pkgs, let me know if you encounter any issues."
