You Can Now Run DOOM Inside DOOM ![In the never ending challenge to get the video game DOOM to run on wildly differing platforms, this programmer managed to run it in DOOM itself.]() *\Image: kgsws/Futurism\* ## DOOM² The port to end all ports: pack it in, boys, because someone managed to run DOOM on DOOM. Tinkering with id Software’s iconic 1993 first person shooter has been an internet tradition for decades. Back in the day, DOOM was a revelation for not only the shooter genre when it was released, but for gaming as a whole. But that was nearly 30 years ago. Now, fans of the game like to amuse themselves by finding different — and often absurd — platforms to port the game to. We’re not talking about porting it to Windows 10 or a random video game console. No, that’s small potatoes. We’re talking [fridges](), [calculators](), [ATMs](), [pregnancy tests](), and even — DOOM itself? That’s right. ## Exploitative After discovering an exploit that would allow them to execute their own code within the original DOOM II, a [pioneering programmer]() known as "kqsws" — with some finagling — used it to import Chocolate DOOM, a modern port of the original game. Their work didn’t end there, though. With greater ambitions in mind, they created an entire map resembling a movie theater multiplex, displaying explanations on their work and posters advertising their other projects. But most importantly, they built a 128 pixel tall screen that flawlessly runs Chocolate DOOM, which you can take control of by pressing F12. And it even runs Heretic, another game based on the DOOM engine. Incredible. Check [out this video]() for a more in depth demonstration, where they also go over some bonus exploits they found. While someone did accomplish a similar feat before them [back in 2015](), that was running code on the modern GZDoom port, not the original game. https://youtu.be/c6hnQ1RKhbo ## DOOMCeption What gamers manage to accomplish in their favorite games is no joke. Maybe next they'll get DOOM to run inside an instance of DOOM that's being run inside DOOM. Hey, if someone’s already managed to create a working 1 Hz [computer inside *Minecraft*](), anything’s possible. **More on running DOOM:** [*New CAPTCHA Forces Users to Prove They're Human by Playing "Doom"*]() ## Author At Futurism, my work has often centered on bringing a sense of clarity and insight to complex topics ranging from the regulation of emerging technologies to the esoteric ideologies of Silicon Valley executives, while striving not to lose the poetic sense of awe inspired by often-obscure fields like astrophysics and quantum computing. I broke the story of CNET using AI to produce articles that turned out to be riddled with factual errors and plagiarism — a dam-breaking inflection point, as I've reported, that's inspired copycats and endless discourse while beguiling stakeholders ranging from tech giants to purveyors of spam around the web. My work at Futurism has been cited by publications including CBS News, the Los Angeles Times, Vice, Gizmodo, Engadget, the Verge, and Vanity Fair. I grew up in locales ranging from India to China, and now live in the exotic suburbs of Virginia. In my free time, I'm an avid reader of weird sci-fi literature, an aficionado of East Asian cinema, and, regrettably, a relapsed gamer. Allegedly, I’m working on a debut novel, currently untitled. ### Author social links [Bluesky]()
