View source for Sega Mega Drive/Priority

The [[Sega Mega Drive]] VDP draws [[Sega Mega Drive/Planes|planes]] and [[Sega Mega Drive/Sprites|sprites]] on the screen in a specific order. In addition, each tile within a plane and each sprite has a '''priority''' bit which can be set to draw it in front of those without. The drawing order is as follows:

# Background colour (set by [[Sega Mega Drive/VDP registers#07|VDP register 07]])
# Background (Plane B) with priority bit clear
# Foreground (Plane A) with priority bit clear (also shadowed in [[Sega Mega Drive/Shadow and highlight|shadow/highlight mode]])
# Sprites with priority bit clear
# Window Plane with priority bit clear
# Background (Plane B) with priority bit set
# Foreground (Plane A) with priority bit set (also normal in [[Sega Mega Drive/Shadow and highlight|shadow/highlight mode]])
# Sprites with priority bit set
# Window Plane with priority bit set
