Perhaps. However, am I the only one having problems running programs after
one that uses mem_copy()?  I noticed after running my newest project after
Jiri's sample program that some of my colors were changed(?). When I ran
Windows everything got cleared up, though. Then, I ran Jiri's Aliens! game,
and not only were some of my colors changed, but my game was only running at
about 1/4 speed that it used to. Strange. But then, I made my own little
program using mem_copy(), but that messed some colors up and slowed down my
game as well. What's the deal? I love this new technique, since it made my
hopeless scrolling demo run over 3x as fast with a lot of potential.
However, I do not like the side effects one bit.
