With the intention 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 straightforward: programmers stacksmashing and Konrad Beckmann needed to trick the Sport & Watch to dump its firmware by injecting code into the exterior storage accessed by the Sport & Watch’s tiny microcontroller.

Discovering a model of Doom sufficiently small to suit on the Sport & Watch’s meager quantity of storage was a separate situation.
