Exact Execution Commands for Reproducibility

1. Extracting Serialized Assets & Scripts (AssetRipper)

AssetRipper.Console.exe "C:\Games\TargetGame" --out "C:\DecompiledExport"

2. Extracting ISIL Assembly Disassembly (Cpp2IL)

Cpp2IL.exe --game-path "C:\Games\TargetGame" --output-as isil --out "C:\ISIL_Export"

3. Mono Control Group Decompilation (ilspycmd)

ilspycmd -p -o "C:\MonoExport\Scripts" "C:\Games\MonoGame\Managed\Assembly-CSharp.dll"

4. Method Body Census Execution

python tools/measure-bodies.py "C:\DecompiledExport\ExportedProject\Assets\Scripts"
python tools/measure-owned.py "C:\DecompiledExport\ExportedProject\Assets\Scripts"

Environment Notes

• OS Environment: Tested on Windows 10/11 x64 and macOS (ARM64 Apple Silicon).
• No Third-Party Python Dependencies: All scripts inside tools/ use standard library Python (os, sys, re, http.server, socketserver, shutil). No pip install required.
• PowerShell Execution Policy: If running .ps1 scripts returns a policy restriction error, launch PowerShell with:

  powershell -ExecutionPolicy Bypass -File tools/fix-plugin-pe.ps1 -ProjectPath "C:\UnityProject"
