Obscure audio codec is a perfect fit for the N64
Sorry for the clickbait title. I promise this post delivers: 44100 Hz stereo with near-Opus bitrates using about 4% of the N64’s CPU time.

Could a modern chess engine on a Pentium have defeated Kasparov in 1996?
A fun experiment where I back-port all the improvements we've made to chess engines over the last 30 years and run it on a 1996 Pentium Pro to see what we could have done if only we knew more at the time.

How to run a city builder on 16 MHz
Do you feel spoiled by modern hardware? I know I do. Even the cheapest CPUs have at least 4 cores nowadays, running billions of operations per second. The idea that you could run any software on le…

Jailbreaking the Switch 2
ns2jb is a software-only, tethered jailbreak for the Switch 2. It allows running arbitrary native code as any ordinary sysmodule, and as the built-in fs sysmodule. This lets us run homebrew, reverse engineer and mod Switch 2 games, back up save files off the Switch, and access most of the Switch 2’s peripherals…

Way to Play Super Mario 64: On Apple Vision Pro
Super Mario 64 becomes a living diorama on Apple Vision Pro. Each level sits on your real table, and you walk around it while you play with a game controller. You are the camera: lean in for a closer look, or step around the table to see Mario from any side.

Rendering pretty sky in Around The World game
In the last post, I got the game’s clouds to look passable. But after looking at it during playtesting, I still wasn’t satisfied with the way the overall picture of how sea, sky and clouds came together. With some small tweaks, things started to look a lot better.

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.

Writing a Demoscene Intro for the ZX Spectrum
In the late 80s, I spent an embarrassing number of hours hunched over my ZX Spectrum, typing in Sinclair BASIC programs and rudimentary assembler routines copied from magazines, trying to re-create the Amiga crack intros I’d seen round at a friend’s house. Obviously, they never came even slightly close - but now, many…

500B tokens later: Letting AI agents decompile a first-person shooter
During the last 3 months, I spent some of my time and tokens decompiling a popular first-person shooter. The goal was not to reach a simple proof-of-concept state. Instead, we really wanted an accurate, stable and feature-complete recreation of the game. The avid reader of my blog might have noticed that I had…

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…
