I love software rendering
Sharp pixels, gritty colour banding, and DOS games running at resolutions their own era couldn’t manage. Why I still prefer the software renderer, and why it needs a fast PC.

Porting my 1993 Amiga game to Godot, with an LLM reading the 68000 assembly
Babylonian Twins is an Amiga platformer I built in Baghdad in 1993, in 68000 assembly. This summer an LLM ported it to Godot, and this is what I found when I read back through what it did. The original disks are now free on itch.io.

The "$60 Gaming PC" – AMD BC-250 (2025)
Ok it’s not exactly $60 but you can get the board itself for that amount of money on eBay if you’re lucky, but on average the price is around $70-$100 (as of November 2025) which is still very cheap considering you can play Cyberpunk 2077 on this.

How kernel anti-cheats work
Modern kernel anti-cheat systems are, without exaggeration, among the most sophisticated pieces of software running on consumer Windows machines. They operate at the highest privilege level available to software, they intercept kernel callbacks that were designed for legitimate security products, they scan memory…

The curious case of retro demo scene graphics
The demo scene has a peculiar view on copyright . It roughly boils down to a system of effort - effort in ideas, effort in craft - where the scene polices itself and punishes sceners that steal outright from other sceners. Theft from the outside world, however, is often taken lightly - especially when it comes to…

Improving Heuristics for A* Pathfinding
On my Introduction to A* page I cover the basics of the A* graph search algorithm for finding shortest paths. Here’s an example from the town of Denerim in Dragon Age Origins. Try moving the start and goal to see A* in action:

Should you normalize RGB values by 255 or 256?
Let’s say you’re writing an image processing program. The program takes in an image, converts it to floating point, does some processing and finally saves the modified pixels to disk as 8-bit colors. The question today concerns how exactly the integer-to-float conversion should be done. There are two approaches which…

Correlated randomness in Slay the Spire 2
Here are three true statements about the game of Slay the Spire 2 (in single player): If you pick Neow's Bones in the Underdocks, the random curse is ~54% likely to be Debt.* It is impossible to receive Rebound from the Trash Heap event. Your first fight is 76% likely to drop a potion in Underdocks, and 4% likely to…

OpenClaw isn't fooling me. I remember MS-DOS
The sad days of DOS. Any program could peek and poke the kernel, hook interrupts, write anywhere on disk. There was no safety.

Software rendering in 500 lines of bare C++
In this series of articles, I aim to demonstrate how OpenGL, Vulkan, Metal, and DirectX work by writing a simplified clone from scratch. Surprisingly, many people struggle with the initial hurdle of learning a 3D graphics API. To help with this, I have prepared a short series of lectures, after which my students are…

RTX 5090 and Raspberry Pi: Can it game?
It turns out, you can attach an external GPU to a Raspberry Pi 5. So my natural first question is, can I game on it? Let’s try it out and compare it with some similar computers. Just a quick FTC required note: When you buy through my links, I may earn a commission. For the showdown of crappy gaming computers, we’ll…
