One of the fictional games that are mentioned in the interactive December 28th Black mirror episode, Bandersnatch, can be downloaded from the Internet and played through a ZX Spectrum emulator.
Bandersnatch follows the young computer programmer Stefan Butler as he develops a new kind of game. The storyline is getting wilder, and Butler devotes himself to the task that is at hand with varying degrees of success or failure (as determined by the viewer's decisions.)
Meanwhile, another game developed by Colin Ritman, a famous designer and an employee of the established studio Tuckersoft, and a glimpse of scenes from the episode.
That game, Nohzdyve, is contained in Bandersnatch, not only as a gag, but also as code for the game itself.
Hidden in one of the multiple closing scenes of the story is an explosion of shrieking audio that, when interpreted as programming data for the Spectrum, leads to a non-listed portfolio on a faux Tuckersoft website.
Of the nine listed games, Nohzdyve is the only one with a download link (to be found on tuckersoft.net/ealing20541/nohzdyve/).
When the nohzdyve.tap file is then loaded into a compatible modern ZX Spectrum emulator (try Speccy or Fuse on Windows PC, or the Spectacol, Marvin and Spectaculator Android apps), players can try out the Ritman design themselves.
Nohzdyve can also be loaded onto the original ZX Spectrum hardware.
It lets players steer a character in free fall, pop balloons and avoid obstacles, somewhat similar in concept to mobile 2015-, pc- and consolelook Downwell, although probably not so many prizes from the conventional game sector will win. – AFP Relaxnews
