Okay, I have to ask first and google then:

Has anyone *ever* ported #DOOM to Donald #Knuth​s #MMIX machine?

I think he deserves to see that.

There is no public #DOOM port for #MMIX

Albeit having a fully-fledged simulator laying around called "virtual motherboard" (https://vmb.sourceforge.net/), with a framebuffer, I/O and all.

This could be my next project.

Mailing Prof. Ruckert about this. This cannot stand:
