DOOM on ZX81?!

Post by nollkolltroll »

What if the ZX81 could have been made to play DOOM, what would that look like? No way to know, it simply isn't even remotely possible to code the classic shooter with the poor performance of our beloved door-stopper.
Now however, I've made a 30fps widescreen video of someone playing DOOM episode 1 map1. Enjoy!
Yes, the video file really does play on a real ZX81.

Excellent work - back in 1981 we could only dream of something like this....
