There were games on the Apple (6502-based) which had seven versions of 
any given sprite graphic so that they wouldn't have to be shifted in 
order to display them on the screen.  8-bit game programmers learned 
much about squeezing every last drop of performance out of limited speed 
and memory.

One of the best C64 games was called Pinball Construction Set, which had 
the pinball moving with apparently natural motion and reflecting off of 
barriers of any angle.  I should have looked at the code to see how they 
pulled it off.
