Running DOOM And Super Mario 64 Inside A PDF File

February 2, 2026 by 12 Comments

Although generally described as a document format, PDFs have ballooned from a Postscript-lite format into a mutant featuring XML and JavaScript support, basically turning what once was a fairly simple format into an interactive page. Naturally, this has to be used for good, and that is why we have the Doom PDF project, as well as [Game of Tobi] using that project as the inspiration for a Super Mario 64 port based on the decompiled source code.

The nice thing about the Super Mario 64 version is that it’s stand-alone, running from a 23.5 MB PDF, unlike the Doom PDF which runs the game in DOSBox. The compromise is that Super Mario 64 PDF runs at just a few FPS, with the output in glorious ASCII.

What enables this feat is to open the PDF in a viewer that supports JavaScript, with the PDF.js that comes with most browsers generally allowing for integrated JS in the PDF to be executed. Unfortunately [Game of Tobi] hasn’t released source code for this project, but we hope that this is forthcoming.

While one can argue about the practicality of this whole demonstration from a gaming perspective, it definitely shows that PDF as a format has gotten way out of hand now that it’s even overrun with hellspawn and Italian plumbers.

An Event Badge Re-Imagined As A Cyberdeck

February 2, 2026 by 5 Comments

We’re used to handheld Linux devices of varying usefulness appearing on a regular basis, but there’s something about the one in a video from [Rootkit Labs] which sets it aside from the herd. It’s a fork of a conference badge.

The WHY2025 badge had pretty capable hardware, with an ESP32-P4, a really nice screen, and the lovely SolderParty keyboard. Here it’s been forked, to become a carrier board for their previous project, the Flipper Blackhat. This is a Linux add-on for the Flipepr Zero, and it seems that plenty of people wanted it in a more useful context. The result is something that looks a lot like a WHY badge, but running Linux.

It’s a great shame when badges end up lying unused after the event, and ones like the WHY 2025 badge are a serious effort to make something that endures. Here, the badge endures in spirit by being forked and re-engineered, and we like it a lot. The full video is below the break.
