Root Mods

The following mods are special because they need to be installed directly into the game's Root folder, not through Mod Organizer 2.
Use the Manual Download and follow the instructions provided for each mod.

Failing to install these mods correctly will result in issues.

Each version of the game requires a different patcher to work with xNVSE.
These patchers allow the game to use up to 4GB of RAM and automatically load xNVSE.

Select one of the following patchers based on your game version.

Testing Utilities

1. Restart your PC (otherwise some plugins might fail to load).
2. Install the ML Utilities Checker with Mod Organizer 2, just like the previous mods.
3. Launch the game using the Tale of Two Wastelands option in MO2 (not NVSE).

4. Once the game has reached the main menu, wait a few seconds and you will see a message box from the Utilities Checker.
   If any check fails and the comment doesn't help you find a solution, open a support thread in the ModdingLinked Discord server.
5. Close the game and disable the ML Utilities Checker.
