Part 3: Where Does the Resource.cfg Go? (Crucial!)

This is the single most common mistake. The Sims Medieval does not use the same folder structure as The Sims 3. You cannot just drop a resource.cfg into your The Sims 3 folder and expect it to work. sims medieval resource.cfg

: To enable certain "Core" mods (like the popular Grim's Medieval Core), you often need an accompanying file called d3dx9_31.dll placed in the folder of your installation directory. Verification The Resource

...and place Resource.cfg directly inside your Mods folder (still pointing to Packages subfolder). Priority 500 : This sets the loading priority

To use mods, you need a correctly configured Resource.cfg file placed in your game's installation directory (not the Documents folder).

• Priority 500 : This sets the loading priority. A higher number means the game loads these files later, allowing them to override lower-priority core game files. Standard mods use 500. Never set it to 1000 unless you know exactly what you are doing (e.g., overriding core UI files).
• DirectoryFiles Mods/Files/... : This is legacy code from The Sims 3. In TSM, it’s largely vestigial but harmless. It points to an older modding structure that few modern mods use.
• PackedFile Mods/Packages/*.package : This tells the game: "Look inside the Mods/Packages folder and load any file ending in .package directly inside it.
• PackedFile Mods/Packages/*/*.package : This adds one level of subfolder support. For example, Mods/Packages/Clothes/*.package.
• PackedFile Mods/Packages/*/*/*.package : Three levels deep (e.g., Mods/Packages/Clothes/Female/Dress.package).
• PackedFile Mods/Packages/*/*/*/*.package : Four levels deep.
• PackedFile Mods/Packages/*/*/*/*/*.package : Five levels deep.
