 5+The working of auto port and sprites is working as follows: If the
 6+auto X bit is set then it draws several sprites vertically, and if the
 7+auto Y bit is set then it draws several sprites horizontally; either way,
 8+the X (if the auto X bit is set) or the Y (if the auto Y bit is set) is
 9+advanced by eight after all of the sprites are drawn (not after each one
10+individually). If the auto address bit is set, then the address is
11+advanced after each individual sprite (and remains advanced after it is
12+finished), by 8 for 1bpp sprites or 16 for 2bpp sprites.
