Try using WaitTOF() or WaitBOF(). These will offer you a delay of a maximum
of 1/60th of a second, but with an added advantage. No matter how long your
processing is before the WaitTOF(), you usually will still be synchronized
with the vertical blank (depending on whether your processing takes *more*
than a vertical blank cycle.) Thus whether your code runs on 68000's or
68030's, and whether you have many objects on the scree or just a few, your
game will still run at the same pace. Neat, eh?
