Judging from the wikipedia article i read about it, the commercial could go like this:
Sega Genesis has Blast processing. It is the ability for the CPU to work on one visible section of map while the graphics processor displays another. Since only the visible part of the map is uploaded at any one time, this feature increases the distance that the map can scroll from one frame to the next, resulting in a slightly higher refresh speed and unnoticably higher effeiency than Nintendo's processing units. Isn't that awesome to the MAX, kids?
