====== SM64 List of Segments ======
SM64 often uses segmented addresses for certain regions of memory. There is a mapping table stored in RAM that is used to keep track of the base virtual address of each segment. This is used for both graphics data that is passed to the RSP and overlay data that changes depending on what the [[super_mario_64:level_commands]] load.
The SM64 (U) ROM stores the segment table at RAM address 0x8033B400.
