-- Inside Mod Engine folder, edit the "config_eldenring.toml" file
Replace the external_dlls = [] line with the following
VERY IMPORTANT, you must have 2 of the \\ slashes between each folder in the paths.
external_dlls = ["C:\\Program Files (x86)\\Steam\\steamapps\\common\\ELDEN RING\\Game\\SeamlessCoop\\ersc.dll"]
Save file and then run the elden ring batch file like you used to.
If you want to do Seamless Co Op & Mod Loader, use this line instead which has paths to Seamless & Mod loader's .dlls . Each external .dll mod, must be in cased within "" with a comma between each .dll location
external_dlls = ["C:\\Program Files (x86)\\Steam\\steamapps\\common\\ELDEN RING\\Game\\SeamlessCoop\\ersc.dll", "C:\\Program Files (x86)\\Steam\\steamapps\\common\\ELDEN RING\\Game\\dinput8.dll"]
