How DOOM fire was done
The Game Engine Black Book: DOOM features a whole chapter about DOOM console ports and the challenges they encountered.

Let's remove quaternions from every 3D engine (2018)
To represent 3D rotations graphics programmers use Quaternions . However, Quaternions are taught at face value . We just accept their odd multiplication tables and other arcane definitions and use them as black boxes that rotate vectors in the ways we want. Why does $\mathbf{i}^2=\mathbf{j}^2=\mathbf{k}^2=-1$ and…

Why did I spend 1.5 months creating a Gameboy emulator? (2017)
For me, the most favorite type of a computer program is an emulator. Being able to run code from a completely different hardware architecture always seemed like a magic. The old computers are great on their own, so this kind of connection between historic machines and the modern computing environment feels almost like…

FizzleFade
I enjoy reading a lot of source code and after 15 years in the field I feel like I have seen my fair share. Even with a full-time job, I still try to spare evenings here and there to read. I don't see myself ever stopping. It is always an opportunity to learn new things to follow somebody's mind process. Every once in…

The Most Mario Colors
The Mario franchise has two distinct logo styles. The first began with the Mario Bros. arcade game and is mostly used for side-scrolling Super Mario Bros. games, though not all of those games use that style. The second is a multicolor polygonal style, and though it’s primarily used for 3D Mario adventures now, it was…

I've been obsessed with procedural maps since I was a kid rolling dice on the random dungeon tables in the AD&D Dungeon Master's Guide. There was something magical about it — you didn't design the dungeon, you discovered it, one room at a time, and the dice decided whether you got a treasure chamber or a dead end full…

Original Pong did not have any code or even a microprocessor
Here is a link to full schematics. Thanks to whoever made this. I just found a few issues with it. The CLK input to the 7474 on page 2 should be HRESET, not CLK. Pin 5 of the 555's on pages 5 and 6 should be connected to the capacitor. Also some of the nodes are inconsistently labeled.
