768 game data bytes reserved here in routine at 49053. This was originally code that drew the decorative border graphics at the start of the game. This routine will not run again so can be overwritten.

These dynamic sets work as follows:

• Each room item - including scenery graphics, doors, objects, creatures and missiles - is copied to and from here as they are set up and handled from the item graphic data buffer at 60227
• The exception is the foreground scenery objects at the bottom of the room, which are handled in a separate table at 32513
• The main routine that copies the data here is at 57520
• Not all 48 banks are used, as there aren't this many different graphic elements in any screen, so later banks still contain code from drawing the aforementioned screen border etc.
• 255 in the first byte of a data bank marks the end of the item sets needed for the current room.

Byte	Value
1	Graphic type (see 60227)
2 & 3	For doors, address in connecting door table at 26512 For interactable objects, address pointer to object table at 29551 For missiles, address pointer to missile table at 27868 For creatures, address pointer to creature type in table at 27772
4	For missiles, missile number (1-9, table at 27868) For creatures, creature type (see 60230) For interactable objects, graphic number in item table at 29551
5	Prevision/overflow byte for screen horizontal position (see next byte)
6	Horizontal position of graphic in room, in 4-pixel (half-character) steps
7	Prevision/overflow byte for screen vertical position (see next byte)
8	Graphic vertical position within current room, in pixels, from top of room playing area
9	64 for various room items 255 for (general) tunnel 254 for tunnel item (boundary, spider, bat)
10	Missiles - difference between horizontal (X) position of missile and target (e.g. Maroc), in 2-pixel increments (negative if target to the left, positive if target to the right)
11	Missiles - difference between vertical (Y) position of missile and target (e.g. Maroc), in 2-pixel increments (negative if target is below, negative if target is above)
12	Item properties: Bit 0 (1) set = item is visible in the current screen (0 = item is off-screen) Bit 1 (2) set = item is hidden (e.g. in a chest) Bit 2 (4) set = item needs erasing (e.g. it's moved position) Bit 3 (8) set (doors) = door is open (0 = door is closed) Bit 3 (8) set (items) = item is moving, e.g. has been dropped/thrown by the servant Bit 4 (16) set (items) = currently carried by servant Bit 5 (32) set (doors) = door opening/closing has been triggered Bit 6 (64) set (items) = item is portable Bit 6 (64) set (doors) = this door is opening or closing Bit 7 (128) set (doors) = Maroc has just gone through a doorway Bits 5-8 (Missiles) = existence time for missile (from second data byte from missiles table at 27868)
13	Pre-graphics data byte Bits 0-3 = number of graphic frames for object Bit 5 = graphic is 'flippable' if set Bit 6 = graphic has left/right facing frames Bit 7 = graphic is animated if set
14	Graphic address frame offset (>1 for mirrored graphics frames)
15 & 16	Pointer to the address for this graphic in table at 38851
