; Bonk Prize Data ($AABB00 - $AABBFB)
;--------------------------------------------------------------------------------
; This table stores data relating to bonk locations for Bonk Drop Shuffle
; 
; Example: We can use OWBonkPrizeTable[$09].loot to read what item is in the
; east tree on the Sanctuary screen
;--------------------------------------------------------------------------------
; Search Criteria - The following two fields are used as a unique index
; .owid         = OW screen ID 
; .yx           = Y & X coordinate data *see below*
; 
; .flag         = OW event flag bitmask
; .loot         = Loot ID
; .mw_player    = Multiworld player ID
; .vert_offset  = Vertical offset, # of pixels the sprite moves up when activated
;
; .yx field is a combination of both the least significant digits of the Y and X
; coordinates of the static location of the sprite located in a bonk location.
; All sprites, when initialized, are aligned by a 16 pixel increment.
; The coordinate system in LTTP is handled by two bytes:
;        (high)             (low)
;   - - - w  w w w s   s s s s  s s s s
;   w = world absolute coords, every screen is $200 pixels in each dimension
;   s = local screen coords, coords relative to the bounds of the current screen
; Because of the 16 pixel alignment of sprites, the last four bits of the coords
; are unset. This leaves 5 bits remaining, we simply disregard the highest bit
; and then combine the Y and X coords together to be used as search criteria.
; This does open the possibility of a false positive match from 3 other coords
; on the same screen (15 on megatile screens) but there are no bonk sprites that
; have collision in this regard.
