I'm probably burying the lede a little. While front-facing Chain Chomp is undeniably nightmarish, the focal point should be that modder "BudFolk" has created a rudimentary build of the iconic N64 platformer Super Mario 64 for Atari's insolvent console, the Jaguar.
A video, uploaded by BudFolk this past weekend, opens on the famous hub world of Princess Peach's Castle, with polygons fighting for their very life as the Jaguar's RISC processors work with code rewritten directly from the original N64 ROM in pure assembly.
This obviously isn't a matter of direct porting, as the two consoles have entirely different infrastructures on every conceivable level. As such, the code has converted every element of the N64 version - from 3D rendering to sound - to a Jaguar-systems-based "workaround". This requires necessary shortcuts such as removing certain visual elements once out of view and (roughly) halving the original game's framerate from 30 FPS to 12 FPS.
Along with Princess Peach's Castle, we see snippets of Bob-omb Battlefield and Tiny-Huge Island, along with notable enemies and allies including Koopa Troopers, King Bob-omb, and the build's centrepiece: a terrifying, front-facing Chain Chomp. No one would deny that it's an incredibly fragile build - the music itself is seemingly fighting for its life - but it's an interesting exercise in pushing the Jaguar to its limits.
And therein lies the port's purpose. BudFolk notes that they are not planning on recreating the full game or even releasing this build as a playable demo, but that they are simply experimenting with the Jaguar's capabilities and nothing more.
It is noted in the video's description that the build is running on BigPEmu. This would likely boost the game's speed. An additional video, shown above, features the build running on original Jaguar hardware. There is a slight drop in performance, though impressive nonetheless. Speaking of the video's description, the highly detailed write-up reads as though it may have been written (or perhaps just translated) by A.I. Of course, this naturally leads to questions about how "vibecoded" the build itself might be.
Regardless, BudFolk's Jaguar experiment joins a bevvy of recent projects that have seen Super Mario 64 running on alternate hardware, including SNES, Dreamcast, Game Boy Advance, and PC. It's certainly a focal point on the homebrew scene, and the community are unlikely to rest until our Brooklyn Boy has Wahoo'd his way onto every platform in existence.
