Features

BUTRLoader consists of two parts- BUTRLoader itself and LauncherEx.

BUTRLoader expands the game launch with the following features:

  • []Interceptor - BUTRLoader checks if the is a class with a custom attribute named BUTRLoaderInterceptorAttribute. If it's found it checks if there are the following signatures:

    [] void OnInitializeSubModulesPrefix() - will execute just before the game starts to initialize the SubModules. This gives us the ability to add SubModules declared in other programming languages like Python and Lua

    []void OnLoadSubModulesPostfix() - will execute just after all SubModules were initialized

    LauncherEx is the UI module. It expands the native launcher with the following features:

    • []Option Tab - provides Game and Engine options, plus the following Launcher options:

    • []Extended Sorting - the launcher now respects the community metadata when sorting. Enabled by default.

      []Compact Module List - allows a more compact display of the Module List. Disabled by default.

      []Fix Common Issues - the launcher checks if 0Harmony.dll is present in the main /bin folder. If there is one, will prompt the user whether to delete it.

      []File Unblocking - the launcher will unblock the .dll's if they are locked itself. Enabled by default.

      []Beta Sorting - uses the new algoritm for sorting modules. Tries to respect existing load order when applying a new load order.

      []Big Mode - extends the height of the Native Launcher window.

      []Save Sub Tab - shows all available saves, some metadata, plus their load order. Allows to continue a specific save and to import/export a save's load order.

      []Scrollbar - the launcher before e1. 7. 2 didn't had a way to scroll without the mouse wheel. We added a scrollbar to fix this.

      []Enable/Disable All Mods Checkbox - added the ability to enable and disable all mods with one click.

      []Resort Modules Button - will forcefully reset the module list and force the raw loaded list to be sorted.

      []Expanded Dependencies Hint - added our community metadata to be displayed in the Hints added in e1. 7. 0.

      []Issue Hint System - the launcher displays an arrow that when expanded, will display why a mod can't be enabled. The issue can be a wrong dependency module version, binary incompatibility with the current game version

      [*]Binary Compatibility Check - the launcher will check whether the are ABI issues in the mod

🤖 AI-enhanced — based on mod data

BUTRLoader is a launcher extension for Mount & Blade II: Bannerlord that fixes mod load order sorting issues, particularly for Harmony, UIExtender, ButterLib, and MCM. The author recommends switching to BLSE instead. It has 6,799 endorsements and 376,613 downloads, last updated in April 2023.

✨ Key Features

Heavily extends the native launcher.
Adds support for community used metadata to fix sorting issues with mod load order.
Correctly sorts Harmony, UIExtender, ButterLib, and MCM.
Author recommends switching to BLSE (Bannerlord Software Extender) if possible.

📊 Pros & Cons

✅ Pros

  • Huge community trust with 6,799 endorsements and 376k downloads.
  • Solves a real pain point: mod load order sorting for popular framework mods.
  • Actively maintained until April 2023, with a clear successor recommended.

⚠️ Cons

  • Author explicitly says to switch to BLSE, so this is effectively deprecated.
  • May not be compatible with the latest game versions since it's not updated after April 2023.
🎯 Is This For You?
For Bannerlord modders who need a reliable launcher to fix load order issues with Harmony and other core mods. If you're already using BLSE, skip this. If you're on an older game version and want a proven launcher, this works, but consider migrating to BLSE for future support.
📦 Install:Easy· Under 1 minute

💡 Beginner Tips

  • Since the author recommends BLSE, check if BLSE is compatible with your game version before installing this.
  • If you're using Vortex or MO2, you can install this as a mod and let the manager handle it.
  • Make sure to place BUTRLoader in your Modules folder and enable it in the launcher, but be aware it may conflict with other launcher extensions.
