The iBookGuy's video, below, on oldschool graphics is an easy-to-understand explanation for how developers of games on the likes of the Nintendo Entertainment System and the Commodore 64 created vibrant visuals despite having next to no computer memory to work with.
We see how developers used workarounds to get more out of the systems they were working with, some of which had just 16k of RAM. There's some pretty interesting stuff in there about pixels, colours, and sprites.
Did you know Mario was made up for multiple sprites? I didn't.
