Well, for every problem there's a "best compromise". If you're doing a
full height single scannline screen and sooooo desperately need the
cycles, you can do a "2 giant tables" solution instead of the "1 giant
table solution", having one table with the missle located after 160
lines of zeros and a second table with the missile located before 160
lines of zeros.
