@metaltao I made a snazzy little generic singly-linked list module for C and then used it to create a snazzy dirty rectangle system for SDL apps. I tried it out on a game's source code to make it run faster on my little laptop, but I did not get around to making the staggered screen-sliding system that is necessare to make the dirty rects useful.

@loveydoe What's a dirty rectangle? And, that sounds liek a lot of work! I am proud of you! ^3^

@metaltao It is a rectanglular area of the screen marked as needing to be redrawn. Updating a few small dirty rectangles is faster than updating the whole screen, which is what makes dirty rectangles useful for games with few moving on-screen objects.

@loveydoe OH! So it is like, rationing the use of power? Aye, I like that, using all your power on one area and Blitzing through the rest. That's incredible!

It is a very clever indeed. It lets me play games, at least!

@metaltao I suspect that games like Sierra's Pharaoh used staggered screen sliding because not only is the game tiled, but it also would have made small screen updates possible due to the small amount of things on-screen that move, and this would make the game easier to play without powerful graphics cards. This is just a suspicion, though.
