If you want to verify that NeosModLoader is working you can check the Neos logs.
Add the following to Neos's launch options: -LoadAssembly "C:\full\path\to\NeosModLoader.dll", substituting the path for wherever you put NeosModLoader.dll. You can create the folder if it's missing, or simply launch Neos once with NeosModLoader installed and it will be created automatically. Add mod DLL files to a nml_mods folder under your Neos install directory ( C:\Program Files (x86)\Steam\steamapps\common\NeosVR\nml_mods). Place 0Harmony.dll in your Neos install directory ( C:\Program Files (x86)\Steam\steamapps\common\NeosVR). Download NeosModLoader.dll to a location of your choosing.
