The first slot, which holds the sheriff in the town, the outlaw in the duel and the first of the money bags in the stage of the bags. There are fifteen slots of sixteen bytes. The first byte of a slot is the type of the object, which is zero for a slot which is not used. The layout of a slot is: byte 0 the type; bytes 1 and 2 the horizontal position; bytes 3 and 4 the vertical position; byte 5 the speed; byte 6 the heading, in bits 6 and 7, with zero for up the screen, one for the right, two for down and three for the left, and the time to turn in bits 0 to 2; byte 7 the flags, in which bit 0 says that the object has bumped into something, bit 1 says that it has been drawn and bit 6 says that it is flipped; bytes 8 and 9 the half width and the half height; bytes 10 and 11 counters; byte 12 the walking frame, in which bit 2 chooses the second set of frames; byte 13 the vertical offset; and bytes 14 and 15 the address of the sprite list.
