Bruce Everiss (featured in that documentary, one of the key people behind Imagine) was head of marketing (or something) for Codemasters when I worked there circa 2000
There was a company wide joke that nobody knew exactly what he did.
The 'Tuckersoft ' set on Black Mirror's version of Bandersnatch had clearly used that documentary for inspiration
'Following success in the C64 market, Euro-Byte commissioned a port of the game to the BBC Micro. However, no source code was available as the game had been coded in 6502 assembler directly into the C64's monitor program. The game was re-written from scratch. Euro-Byte subsequently commissioned a version for the Acorn Electron, but this was never released. ' Game programming on 8bit in 80s was really a dark art and still a mystery no standard libraries. We are still seeing new games we techniques that were not used back then when speed of release was the key.
As an Acorn Electron Elite player I am still waiting for suns . Ironically we are still dealing with platform limitations.
Elite wasn't released on wii Switch weather that was a business or technical reason is unclear. The native mac has had issue because of the way opengl doesn't support shaders.
