At its core, the resource.cfg file is a plain text configuration file used by the proprietary game engine behind The Sims Medieval (the same engine powering The Sims 3 ).

Priority 501 DirectoryFiles Files/... autoupdate PackedFile Mods/Packages/*.package PackedFile Mods/Packages/*/*.package PackedFile Mods/Packages/*/*/*.package PackedFile Mods/Packages/*/*/*/*.package PackedFile Mods/Packages/*/*/*/*/*.package Use code with caution. Click . Change the "Save as type" dropdown to All Files ( . ) . Name the file exactly: resource.cfg Save the file. Step 4: Place the File in the Correct Directory
