Every game for the arcade that I have work on or taken apart was 60
FPS. This made the graphics smooth.
Now, most of my CoCo game never ran at 60 FPS because of the speed of
the coco and the work that was needed per game frame. But the CoCo was
design to be a cheap home computer that could do many things. An arcade
game (like Zaxxon) was design to play just one game with hardware tuned
for just that task and at cost 25 times higher.
