MDL Files

These seem to be simple model files containing the required information to render 3D objects. They're also used in some 2D backgrounds (like 2879436369) for bones.

NOTE: This documentation page is not completed yet as there's still work left to do on the reverse engineering of this file format. For now just a structure, describing the file format is here
