; map group ids
; `newgroup` indexes are for:
; - MapGroupPointers (see data/maps/maps.asm)
; - MapGroupRoofs (see data/maps/roofs.asm)
; - OutdoorSprites (see data/maps/outdoor_sprites.asm)
; - RoofPals (see gfx/tilesets/roofs.pal)
; `map_const` indexes are for the sub-tables of MapGroupPointers (see data/maps/maps.asm)
; Each map also has associated data:
; - attributes (see data/maps/attributes.asm)
; - blocks (see data/maps/blocks.asm)
; - scripts and events (see data/maps/scripts.asm)
