Get run Doom in an unconventional environment, that is, beyond the types of devices for which it was designed, it is something that will never go out of style. We’ve seen it in calculators, in smartwatches, in motherboard BIOS, in Minecraft… and twice, etc. We can almost take it for granted that any screen with some electronics behind it is likely to be a platform for Doom to run on. For better or worse, it means less, though we’ve seen some truly admirable implementations over the years.

And today we learned about a new step in this direction, a step that is also so logical that I can’t help but wonder if this was the first case. And it is because youtuber kgsws posted a video in which we can see the original Doom running inside Doom II, specifically the MS-DOS version of the second part of the saga. But that’s not all, it also explains step by step how it can be done.

It is necessary, yes, to use the MS-DOS version of Doom II because To achieve this, he used an exploit that is exclusive to this version. and this uses the animated textures feature to display an image of the original Doom on a virtual screen on the in-game map. So if you think it’s the right time to pick up Doom II and want to take a break mid-game by watching the predecessor, this option is probably what you’ve been looking for.
