====== Levels ======
Levels are contained in two gzip blocks. e.g.:
chimp.raw: level data for Simian Acres
chimp_dl.raw: display lists for Simian Acres
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 [[blast_corps: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.
===== List of Levels =====
The function at 0x8025615C is used to lookup and copy the level data files from level ID and is implemented as a switch statement with the following lookup:

==== 0x24: Y Collision ====
These are additional collision triangles set up to prevent J-Bomb from clipping through structures from above. In levels that contain the J-Bomb, triangles are drawn around the semi, tunnels, and other things it probably shouldn't mess with from above. Also, the large gray area surrounding the crane in Ironstone Mine is defined with these.
