turtius on YouTube managed to run a Minecraft server on their Canon EOS 200D (as you do). They did it by modifying Avrcraft, a Minecraft server optimised for 8-bit devices, to work with Magic Lantern, a firmware add-on for Canon DSLR cameras.
While I won’t be trying this with my DSLR, if you have a spare one lying around and you have the skills, maybe you could give it a go.
And, I know what you’re gonna ask… “but can it run DOOM?” and the answer is yes.
