The story of an old-timey programming hack

I thoroughly enjoyed reading Tom Moertel’s tale of a great old-timey game-programming hack, it reminded me of my computer science days and assembly programming.

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, so the gaming hardware was almost impossibly slow by today’s standards.

It might not surprise you, then, to learn that, back then, game programmers did all sorts of crazy things to make their games run at playable speeds. Crazy, crazy things.

This is a story about one of those things.
