Il2CppDumper for Windows

Overview of Il2CppDumper

Il2CppDumper is a free, specialized utility for working with Unity applications built using the il2cpp scripting backend. It helps extract internal metadata, produce placeholder DLLs, and inspect binary layouts so developers and modders can examine how a Unity game or app is structured under the hood.

Core capabilities

• Generate stub or placeholder DLL assemblies from il2cpp binaries to aid in debugging and tooling.
• Parse and export metadata and type information from Unity projects compiled with il2cpp.
• Provide tools for in-depth inspection of code organization and binary symbols.
• Offer an approachable graphical interface alongside command-line options for automation.

Common use cases

• Troubleshooting crashes or unexpected behavior by examining application internals.
• Creating mods or custom patches by understanding class and method layouts.
• Integrating third-party analysis tools using the exported metadata and generated DLLs.
• Learning how a Unity build maps managed types to compiled artifacts for educational or research purposes.

Benefits for developers and modders

Il2CppDumper focuses specifically on il2cpp output, making it a targeted option when working with Unity binaries produced by that pipeline. Its combination of extraction, analysis, and DLL generation streamlines tasks that would otherwise require piecing together multiple tools, helping accelerate debugging, reverse engineering, and customization workflows.

Quick start

• Obtain the matching il2cpp binary and global-metadata file from the Unity build you want to analyze.
• Launch Il2CppDumper via its GUI or the command line and point it at those files.
• Use the exported metadata and generated DLLs with your development environment or modding tools to continue analysis or implement changes.
