DLL Muster

DLL Muster – Unity DLL Inspector for REPO Modders

DLL Muster is a powerful Windows tool designed for REPO modders and Unity developers. It lets you inspect, extract, and decompile Unity-based .dll files (like Assembly-CSharp.dll) used in the game REPO.

This tool is built specifically to help reverse-engineer internal game logic, view class structures, and export readable .cs files for custom mods and patches.

• []Drag-and-drop interface for quick DLL inspection

  []Export all class info, methods, and fields to .json

  []Extract full decompiled .cs source files per class

  []Bulk export support (multiple DLLs at once)

  []Supports dnlib and ILSpy (ICSharpCode. Decompiler 9.x)

  []Built for Unity/REPO modding workflows

  Use Case for REPO

  Whether you’re modding REPO’s loot logic, level generators, player stats, or UI systems, DLL Muster helps you:

  • []Understand REPO’s core architecture (Assembly-CSharp.dll)

    []View and log method and field names for patching

    []Export scriptable object classes for plugin targeting

    []Decompile actual logic (e.g. ValuableDirector, LevelGenerator, etc.)

    No need to load up dnSpy or ILSpy manually — DLL Muster is purpose-built for modders.

  • []Launch DLLMusterGui.exe

    []Drag REPO’s Assembly-CSharp.dll into the interface

    []Click:

    • []Extract to .json to get method/field data

      []Extract to .cs to get full decompiled source files

      • []All outputs are saved to your selected folder

        []Use the exported code to guide Harmony patches or plugin injection

            Q: Can this edit or patch the DLL?

            A: No — it’s read-only and focused on inspection and export. Use Harmony or BepInEx to inject behavior.

            Q: Is this better than dnSpy?

            A: It’s simpler and faster for exporting .cs or .json without needing to explore everything manually.

            Q: Will it work with non-REPO Unity games?

            A: Yes — any Unity Assembly-CSharp.dll or plugin DLL can be inspected.
