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.
