City building games have a Soul Problem pt.2
Despite my disappointment with Cities: Skylines 2, I keep coming back to the game from time to time. I can't even control it. It's like a deep inner need....

Infidel goes wild
Planetfall was yesterday's public release, but of course I've spent the past few weeks concentrating on Infidel. A couple of days I came across the most egregious bug I've yet seen in an Infocom game. This bug is extremely difficult to detect ...

SDF vs. MSDF vs. Slug: GPU Text Rendering
The real difference between texture-atlas, SDF, MSDF, and Slug glyph rendering on the GPU: how each works, where each breaks, and when to use which.

I play Factorio the normal way: by writing matrix math code to plan the factory.

Software occlusion culling in Block Game
My GPU is the integrated Radeon Vega 8 that comes with my AMD Ryzen 7 5700G CPU. I tell you this so you know that my workstation is not a graphical computing powerhouse. It is, in fact, quite weak. To its credit my integrated GPU shows up as 48% faster on UserBenchmark than the GPU in my low end hardware target; a…

Amiga Screens: A Primer
One of the unwritten rules of the Internet seems to be that whenever something Amiga-related is mentioned, at least one Amiga fan (myself included) must show up and try to explain the concept of screens . Amiga screens can have different resolutions, we'll tell you, and one can drag them, we'll say, and other Amiga…

Apple Copland D11E4 Booting in the Browser
Apple’s ill-fated Copland operating system is notoriously hard to run on real hardware, and has not previously been available in emulation. Here is the last build, D11E4 from June 1996, in an improved DingusPPC.

How video games inspire great UX (2019)
This quote is meaningful to me as I’ve often struggled with a problem until an insight from a user test “changed my perspective”.

Divide by depth for instant 3D
When I first started working on games, I used high level frameworks that would give you a Camera that just kind of worked. But as I learned more and wanted t...

The Effect of CRTs on Pixel Art (2024)
A follow-up to this text is available here . It goes into much greater detail about signal quality, and also examines how pixel art techniques have been used on non-CRT systems.

The Lamentable Later Life of Lemmings
For a while there in the early 1990s, there seemed to be good reason to believe that Lemmings was on its way to becoming one of gaming’s perennial franchises. Developed by DMA Design of Dundee, Scotland, the original Lemmings game took the world by storm upon its release in 1991. From its first home on the Commodore…

A custom virtual machine for the Stars 4X game
Stars! is a 1995 4X game (explore, expand, exploit, exterminate) for 16-bit Windows 3.1 that I first played ~28 years ago. While Windows is famously backwards compatible, it’s notoriously difficult to play Stars! today. Windows x64 cannot run 16-bit applications, and playing requires either retro hardware or emulation…

Recreating Voodoo Graphics and a Late-1990s Gaming PC on an FPGA
I've spent the last month adding features and improving performance in z486_MiSTer , mostly working through games from the first half of the 1990s. Looking a few years ahead brought me to another change I wanted to explore: the arrival of 3D graphics cards.

Lucasart's Afterlife
I can hardly believe I’m writing a blog post about a game that came out 27 years ago, but here we are. Lucasfilm, at one time had a gaming subsidiary called Lucasarts, and they produced somet…

Reversing Factorio's RNG
This post details how Factorio's random number generation works, how it can be reversed and how I used that knowledge to predict and manipulate the RNG with pure in‑game mechanics.

ZX Spectrum: Experimenting with 1-Bit Sound
As part of the ZX Spectrum tour, I implemented some routines that would let you play simple tones out of the 1-bit beeper. These were in large part inspired by earlier work I did on the Apple II. W…

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.

Sony makes bold claim about game ownership
Sony would like you to know that any reasonable gamer would know that purchasing a game is just licensing a game (Video Games Chronicle), not owning it. And there is truth mixed in with a bold-face…

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.
