IL2Cpp Reverse-Utility Suite

A small collection of two command-line helpers for working with Unity IL2Cpp binaries:

Tool	Purpose
IL2CppExtract	Scans an IL2Cpp‐ generated executable or shared library and lists the RVA offsets of every field and method it finds.
UnityMapper	Uses the RVA list to translate obfuscated class back to their real names.

These tools aim to make reverse-engineering mobile and desktop IL2Cpp games a little less painful.

📦 Quick start

# Clone
git clone https://github.com/AlpaGit/IL2CppExtract.git
cd IL2CppExtract

# Change for your configuration
You probabily will need to change the directory of your game folder in the Program.cs

# Build everything (requires .NET 9 SDK)
dotnet build -c Release

• Start IL2CppExtract and it will create a Output folder with multiple directory of libaries containing every static fields
• Copy the Types.bin and the Classes.json from Output/Ankama.Dofus.Protocol.Game to the UnityMapper tool and it will create a json mapping of the classes
