Jurassic Park computers in excruciating detail
After I mentioned a Jurassic Park anecdote the other day , I watched the movie again. I must have seen it at least ten times now. This time, I researched every computer/software I spotted.

Observing my cellphone switch towers
One of my favorite books is 2013 "High Performance Browser Networking" by Ilya Grigorik. Besides a wealth of actionable advice, the book is illustrated with captivating real life stories.

A Linux Evening
I love to have Linux as my main OS. For someone who spends most of his time programming, writing HTML, writing LaTeX, and browsing the net, it is nearly a perfect tool. Packages are one "apt install" away. Mounting my website is one sshfs away and with private key authentication I don't even have to type my password…

The Polygons of Another World
There is a playful way to study the architecture of computers of the past. Find a piece of software you know well and try to find out how it was ported to these machine you don't. A good choice would be DOOM. id Software's 1994 mega-hit has been ported to everything. It is designed around a core with no layering…

Why fastDOOM is fast
During the winter of 2024, I restored an IBM PS/1 486-DX2 66Mhz, "Mini-Tower", model 2168. It was the computer I always wanted as a teenager but could never afford. Words cannot do justice to the joy I felt while working on this machine.

How DOOM fire was done
The Game Engine Black Book: DOOM features a whole chapter about DOOM console ports and the challenges they encountered. The utter failure of the 3DO, the difficulties of the Saturn due to its affine texture mapping, and the amazing "reverse-engineering-from- scratch" by Randy Linden on Super Nintendo all have rich…

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…

Street Fighter II paper trails – allocating sprite space by hand
The late 90s saw the emergence of Capcom in the world of arcades. The Osaka based company seemed to produce one hit after another with Ghouls'n Ghosts in 1988, Final Fight in 1989 and Street Fighter II in 1991 among a myriad of other excellent games.

Inside the Super Nintendo cartridges
One of the remarkable characteristics of the Super Nintendo was the ability for game cartridges (cart) to pack more than instructions and assets into ROM chips. If we open and look at the PCBs, we can find inside things like the CIC copy protection chip, SRAM, and even "enhancement processors".

How Quake.exe got its TCP/IP stack
Released in June 1996, Quake had to ride three technological shock-waves during its lifetime. Besides the emergence of 3D hardware accelerator cards and the growth of the Internet, an operating system shift put game developers in a tough position.

USB Cheat Sheet (2022)
I spend time investigating a non-existing bug today because I misunderstood a USB term. So I made myself a cheat sheet. Maybe it will save time to someone.

Quake Shareware, a CD-ROM just a little too full
In the mid-90s the coolest thing to buy for a PC, besides the incredibly expensive Intel Pentium , was a CD-ROM drive . With their capacity of 640 MiB (three times the storage of PC HDD at the time), CDs allowed enthusiasts to step into a world of multimedia, made of high-resolution 640x480 256 colors palette-indexed…

The 3dfx Voodoo1
This article is the second entry in a series about the "3D cards of the late 90s running Quake". The first entry [1] took a look at the end of 1996 with the Rendition Vérité 1000 and its dedicated port called vQuake. Rendition had managed to beat everybody to Quake-market. For a brief period of time they had the one…

Floating Point Visually Explained
While I was writing the Wolfenstein 3D book [1] , I wanted to demonstrate how much of a handicap it was to work without floating points. My attempts at understanding floating points using canonical [2] articles [3] were met with resistance from my brain. I tried to find a different way. Something far from $(-1)^S *…

Game Engine Black Books Update
I have kept myself busy with the Game Engine Black Books and I have plenty of news. Most importantly, they have been revised. The DOOM book is now in version 1.1 while the WOLF3D book is entering v2.1. And there is more.

All you may need is HTML
Readers occasionally request which static HTML generator is used by fabiensanglard.net , and if they can take the same stylesheet/ fonts to start their own blog. I usually send back the whole 134 lines of gen.php [1] and invite them to copy whatever they need to get started [2] .

Street Fighter II, the World Warrier (2021)
This article is part of a series about Street Fighter II and the CPS-1. It is recommended to read the previous entries before reading this one.

Commander Keen's adaptive tile refresh
I have been reading Doom Guy by John Romero. It is an excellent book which I highly recommend. In the ninth chapter, John describes being hit by lightning upon seeing Adaptive Tile Refresh (ATR). That made me realize I never took the time to understand how this crucial piece of tech powers the Commander Keen (CK)…

My agent.md to improve LLM-assisted code quality
The first time I tried to use an LLM to speed up coding was in mid-2025. I was not impressed. I was working on libadbmdns back then, an mDNS implementation in Rust. The code produced would not even compile.

How the Devteam Conquered the iPhone
The summer of 2007 was an eventful one if you were into cell phones. It all started on June 29 when Apple announced the release of the iPhone. If you have never taken the time to watch the full keynote, I highly recommend it.

Discret 11, the French TV encryption of the 80s
I spent my childhood in France, playing a lot of soccer and watching way too much TV. In the 80s, there were three channels available. Two of them, Antenne 2 and FR3, were state funded and boring while TF1 was privatized and offered plenty of Japanese cartoons. My generation grew up with Captain Tsubasa, Saint Seiya…

Mjolnir
As much as I loved the beautiful machine , the passive cooling and form factor of the DB4 chassis had limitations. The best GPU I could fit in (and cool down), a 1050 Ti, barely managed to run Diablo 2 Resurrected. Playing could become unpleasant at 30fps in busy levels!

To become a good C programmer (2011)
Every once in a while I receive an email from a fellow programmer asking me what language I used for one of my games and how I learned it. Here is an entry that list the best things to read about C. If you know of other gems, please email me or add a comment at the bottom of the page.

Deciphering the Business Card Raytracer
I recently came across Paul Heckbert's business card raytracer. For those that have never heard of it: It is a very famous challenge in the Computer Graphics field that started on May 4th, 1984 via a post on comp.graphics by Paul Heckbert ( More about this in his article " A Minimal Ray Tracer " from the book Graphics…

Quake 2 Source Code Review
I spent about a month in my spare time reading the source code of Quake II. It was a wonderful learning experience since one major improvement in idTech3 engine was to unify Quake 1, Quake World and QuakeGL into one beautiful code architecture. The way modularity was achieved even though the C programming language…

How the Dreamcast Copy Protection Was Defeated
After I shipped the DOOM Black Book , I took some vacation in Japan where I was able to play Ikaruga on a real arcade at Taito HEY in Akihabara. The experience reignited my interest in SEGA's ultimate video game console, the Dreamcast. There is a lot of documentation available online which made the studying process…

Quake 3 Source Code Review: Network Model (2012)
The network model of Quake3 is with no doubt the most elegant part of the engine. At the lower level Quake III still abstract communications with the NetChannel module that first appeared in Quake World . The most important thing to understand is: In a fast paced environment any information that is not received on…

Let's compile like it's 1992 (2014)
I have been tinkering with the vanilla source code of Wolfenstein 3D from 1992. Even though it is more than 20 years old and has rotten for modern systems, you can still compile it if you recreate the environment. All you need is :

These are called opportunities
Yesterday Apple updated three of their machines. During the announcement, it was revealed that the MacBook Air, the MacBook Pro 13", and the Mac Mini would now be running on M1 SoCs. These "One more thing..." events usually comes with raving numbers and this one did not diverge from the tradition.
