The sprite graphics are located at [[$84:8000]] and each 16x16 tile is 0x80 bytes long, so the address of the graphics for a given tile number can be calculated as "0x20000 + TileNumber * 0x80".

=== Solid sprites ===
 
Certain sprite types are considered solid. That is, players andor monsters will not be able to move through them. Sprite types that are solid are highlightedshown in the [[#Sprite types|sprite type]] table above. In addition, types 0x39 through 0x5B are solid to both players and monsters, but these types are not used in the original game.
 
Solid sprites are implemented in a different way from normal sprite collision. An entity must manually call [[$80:BFC8]] to check if a given position is overlappingsolid to players, or [[$80:BF67]] to check if a position is solid spriteto monsters.
 
The area for solid sprites is slightly smaller than for regular collision. A position is considered touching a solid sprite if it is within 6 pixels of the right or bottom, or within 5 pixels of the left or top. The area is smaller so that sprites will trigger regular collision before stopping due to running into a solid sprite.
