Sorry SLZ!
You need:
- MelonLoader
- IL2CPP dumper + IL2CPP assembly unhollower or a copy of of the unhollowed DLLs
- Copy the unhollowed DLLs to a folder called Managed next to the project.
- Copy
MelonLoader.ModHandler.dll
into the same folder. - Open the solution.
- Press build, and the mod will be placed in a new directory titled Output.
