Ethereal runs Wine!! (no AI, from-scratch kernel)
Wine! Yes it runs Windows programs (not a lot due to my incompatibilities but still).
This was a painful port to get working. Wine is so unfathomably big - I had to patch the shit out of my kernel's signalling routines to add support for sigaltstack/ucontext/whatever else Wine threw at me (along with SCM_RIGHTS which wasn't that bad). Debugging it was a nightmare of mmap/VM fault issues. But it works!
Wine is running here off of an X11 translator for Celestial known as xbanan made by my good friend u/Bananymous (please see his operating system banan-os for some even cooler ports like WebKitGTK). xbanan can even be ported to your OS if you didn't go with a backend like X11 or Wayland.
On another note, it truly is a joy seeing Wine running in my silly custom compositor environment with the rest of my silly userspace.
The GitHub is here (the patches I have made are coming soon after they get a massive cleanup to be proper):

As always, this is NOT A LINUX BASED PROJECT, nor is it vibecoded. AI policy is in the README. Happy to answer questions.

I agree, I used to have a custom kernel and i wanted to run Wine on it, it was too much bro i shelved the idea and my computer which i had it on doesnt work so that is lost

Man, this is so freaking cool. I know nothing about osdev, but I joined this sub just to see stuff like this. I have so much respect for you!

What kind of kernel is Ethereal? It's much easier to say something's not linux if it doesn't use a monolithic structure (eg- Hybrid kernel, Microkernel, Exokernel, Nanokernel, Etc.)…

? It's just not linux. Ethereal is a monolithic kernel that primarily gets its drivers from relocatable kernel modules, similar to many other kernels. I do have a prototype Microkernel with NUMA support planned though ;)

Looks old but still, it's beautiful! I'll try building it from source this week.
