# Old Rod

> Old Rod disassembles a .NET executable protected by the KoiVM virtualizer in ConfuserEx and recompiles that VM code to CIL. OldRod.exe --help lists the options. --output-directory sets the output folder, and --koi-stream-name, --entry-type, and --run-sig-1 override detection. --config takes a constants map such as doc/example-config.json. Builds use MSBuild in Visual Studio or Rider. AppVeyor publishes binaries. AsmResolver, Rivers, and Newtonsoft.Json are dependencies.
