How to use if you want to add your keystone file to the fake package:

1-First you must have 'Fake PKG Generator v3.38' in order to use these tools.
2-Extract 'Fake PKG Generator v3.38' to a new folder and copy these tools to the same folder.
3-Run 'gengp4-patched.exe' tool first to generate GP4 file which include keystone in it. ( this is a patched version of Vortex's tool )
4-Run 'orbis-loader.exe' tool to load and patches 'orbis-pub-gen.exe' to add your keystone file when creating fake package.

Finally, I hope that you use these tools in your dumps instead of generating keystone when
creating fake package, so you can have a real working backup with official saves support.
