This currently targets Linux, but the number of entries of this project into the Kernel are exceptionally few, since it compiles all assets into itself, so it is trivially compilable into embedded systems as well. It was originally geared to run on an ESP32-C3, but I never finished that.

It's just designed to be extremely primitive where you update i_video.c with whatever I/O you need.

A few days ago I looked into this again, and yeah that was my experience. The biggest issue I had was that since I'm targetting rv32i without cpu/hardware multiplication+division, libc has to be recompiled with different settings as well. I ended up switching out doomgeneric with embeddeddoom in polkadoom which was linked above. Most of the time was spent fiddling with compiler settings/make files, once I got my toolchain figured out it just took like an hour to remove all the kernel calls.

Haven't actually tested stuff but at least it compiles with my linker script, probably won't look at this for a while but I'll let you know if I have other questions when I do.

Let me know if you run into any further issues.
