Track Rendering
Tracks are rendered by calling F3DEX display lists at each frame.
Each track has a table of RSP addresses pointing to the master display list for each section of the track. Each frame, the game calls the appropriate list based on the player's position and camera angle, and those lists call other lists to render everything that should be visible.
The location of this table is hardcoded for each track:
| Track | Table Loc. | Code Loc. |

| 0x01 Choco Mountain | 09:000150 | 80292C5C |

Table Loc is the location of the table. Code Loc is the approximate location in RAM where the program sets the table location.
The table contains four pointers for each section: one for North, East, South and West respectively. The section index is specified by the Surface Map polygon that the player was most recently sitting on.
In theory, the table can be in any RSP segment, but all tracks place it in either segment 6 or 9. (XXX why two different segments?)
Several - probably all - tracks have a number of hardcoded display list addresses, which are called every frame regardless of the player's position. Mostly these draw objects that are visible from many places (such as Mario Raceway's giant mushroom).

XXX determine order, find where these are called from, and find them for the other tracks.
