Nintendo’s Game & Watch can run Doom, barely

Intrepid builders have accomplished the anticipated and mandatory: Doom now runs on Nintendo’s just lately launched Game & Watch moveable. The Game & Watch: Super Mario Bros. was designed to run three video games, however efficiently porting Doom reveals it can deal with others you probably have numerous endurance (by way of Hackaday).

This model of Doom is just not good, after all. In order to get the sport to run even on the slower pace proven within the video beneath, sound needed to be disabled and textures needed to be simplified to suit the sport on the small moveable. And getting that far wasn’t simple: programmers stacksmashing and Konrad Beckmann needed to trick the Game & Watch to dump its firmware by injecting code into the exterior storage accessed by the Game & Watch’s tiny microcontroller.

Finding a model of Doom sufficiently small to suit on the Game & Watch’s meager quantity of storage was a separate situation. The hackers settled on a bundle referred to as “Minimal Doom IWAD” that replaces the sport’s unique textures with simplified variations, however they nonetheless needed to make additional changes like disabling sound to work throughout the Game & Watch’s 1.1 MB of usable storage.

Doom’s demon-slaying motion wasn’t ported to a Nintendo console till the extra highly effective SNES was launched, so displaying up on a tiny gadget designed to run NES video games is as uncommon as it’s spectacular.

Doom is an outdated standby for programmers experimenting with homebrew video games. The sport has confirmed up in all types of locations: from a Samsung fridge operating xCloud, to a Windows PC in-built Minecraft, and even the Touch Bar of a MacBook Pro. Thanks to this work, Doom appears proper at house on a Game & Watch, and shortly, different homebrew video games may be, too.
