A long time ago, when I was a college undergrad, I spent some time working on computer video games. This was in the 8-bit PC era, when the gaming hardware was almost impossibly slow by today’s standards.
It might not surprise you, then, to learn that game programmers of yore did all sorts of crazy things to make their games run at playable speeds. Crazy, crazy things.
While I’ve done my best to recall the important details, I may have gotten some things wrong. If I have, please forgive me. It was a long time ago.
