Hmm. Would it have been possible for OOTW to get more fluent animation,
despite the 1Mhz bottleneck? I always thought OOTW was slow because it had
to calculate things, not because of the BitBlit.

This is sort of annoying. If I want nice graphics, I lose speed. If I want
speed, I lose resolution. And this with a fast ZIP ... *sigh* I guess it's
time to upgrade to a computer with more horsepower soon :)
