In my game I just needed to enable/disable a missile, and position an object with a cycle 73 or cycle 74 hmove all in 1 scanline. Playing around with how to do this I came up with some fairly economical code. I then made the demo posted below showing the yellow object positioned by a cycle 74 hmove, and the green object positioned by a traditional hmove.   If you are wondering cycle 73 or 74 hmoves hide the black "comb" lines on in an Atari game. The consequence of using cycle 73 or 74 hmoves
