For maximum compatibility with other mods using content0/main.ovl I highly reccomend using cobra tools to inject the provided lua files into your modded main.ovl

The tools are available here:
https://github.com/OpenNaja/cobra-tools



Content0/main.ovl may take a long time to open and save on some people's computers



Alternatively I have provided a main.ovl to use as a standalone mod if you prefer not to inject the lua files.
