Break down of a C64 demo effect
VGA has redefinable character sets. I tried doing some animation with them back in the day, but I ran into some kind of limitation that I don't recall. I was trying to accomplish an animation effect by altering the character definitions in realtime, which I recall being very slow. It never occurred to me to do something like this. Now it'll be everything I can do to stop myself from trying this on an old PC! Goodbye weekend productivity!
