Open Source C# Reverse Engineering Tools

Il2CppDumper is a Unity IL2CPP reverse engineering tool for analyzing supported Unity applications and game binaries. It can restore DLL metadata structures without restoring original code, which helps researchers inspect classes, methods, fields, MonoBehaviour data, and MonoScript information. The tool supports executable formats such as ELF, ELF64, Mach-O, PE, NSO, and WASM. It supports Unity versions from 5.3 through 2022.2, according to the repository documentation. Il2CppDumper can generate helper scripts for IDA, Ghidra, and Binary Ninja, along with structure headers and JSON outputs. It is best suited for authorized reverse engineering, interoperability research, security analysis, modding research, and educational binary analysis.

AssetRipper is an open-source application for analyzing and extracting assets from games developed with the Unity engine. It helps developers inspect compiled game files and recover resources into formats compatible with Unity development workflows. The software can process assets such as textures, models, audio files, and other game resources. It assists in identifying unused dependencies, broken asset references, and code that remains in compiled builds. AssetRipper supports a broad range of Unity versions, although compatibility and extraction accuracy can vary. Its graphical interface makes complex asset structures easier to explore and understand. The application is particularly useful for debugging, recovering project resources, studying game architecture, and investigating Unity build contents.
