Decompiling IL2CPP in Unity using C++

  1. Understand IL2CPP

IL2CPP is a Unity-developed scripting backend that converts IL code (C#) to C++ code. It is used to improve performance and provide platform compatibility.

  1. Obtain IL2CPP Output

After building a Unity project, locate the IL2CPP output files. These files contain the converted C++ code and can be found in the project's build directory.

  1. Decompile C++ Code

Use a decompiler, such as IDA Pro or Ghidra, to decompile the C++ code obtained from the IL2CPP output. The decompiler will translate the C++ code back into a more readable form, resembling the original C# source code.

  1. Review Decompiled Code

Once the decompilation is complete, review the decompiled C++ code to understand the logic and structure. This step involves analyzing the decompiled code to gain insights into the original C# source code.

  1. Modify as Needed

Make any necessary modifications to the decompiled code based on the insights gained. This could involve fixing bugs, optimizing performance, or making other adjustments as required.

  1. Recompile if Applicable

If changes were made to the decompiled code, recompile the modified code to generate the updated IL2CPP output. This step ensures that the changes are reflected in the final build of the Unity project.

  1. Test the Modified Code

Test the modified IL2CPP output to verify that the changes have been successfully incorporated and that the Unity project functions as intended.

  1. Integration and Deployment

Finally, integrate the modified IL2CPP output back into the Unity project and deploy the updated build as necessary. This step ensures that any modifications made through decompilation and recompilation are effectively integrated into the project.
