 The level data begins with a header that contains the offsets in the file for all of the level information (RDUs, buildings, vehicles, etc.). The level data file also contains vertices and other data used by the display list that are loaded into segment 08.
-The display list contains mostly raw F3D commands. The exception is 0xFD G_SETTIMG command which contain indexes to a [[bc:textures#texture_table|texture table]]. At run-time, after the display list is copied to RAM, the texture indexes in the G_SETTIMG are replaced with texture offsets in segment 0x00.

Also, the large gray area surrounding the crane in Ironstone Mine is defined with these.
