This guide will walk through how to decompile/reverse engineer IL2CPP games for modding usage.
Note
This is a fork of a gist by BadMagic100. I modified it to use Il2CppInspectorRedux instead of Il2CppDumper since newer Unity versions use newer IL2CPP metadata versions that are not supported by Il2CppDumper.
Note: expect this entire process to take upwards of an hour. Have something ready to do on the side while waiting for processing to finish.
