; "MAIN LEVEL LOAD BLOCK" (after Nemesis)
;
; This struct array tells the engine where to find all the art associated with
; a particular zone. Each zone gets three longwords, in which it stores three
; pointers (in the lower 24 bits) and three jump table indeces (in the upper eight
; bits). The assembled data looks something like this:
;
; aaBBBBBB
; ccDDDDDD
; eeFFFFFF
;
; aa = index for primary pattern load request list
; BBBBBB = pointer to level art
; cc = index for secondary pattern load request list
; DDDDDD = pointer to 16x16 block mappings
; ee = index for palette
; FFFFFF = pointer to 128x128 block mappings
;
; Nemesis refers to this as the "main level load block". However, that name implies
; that this is code (obviously, it isn't), or at least that it points to the level's
; collision, object and ring placement arrays (it only points to art...
; although the 128x128 mappings do affect the actual level layout and collision)
