Is there a scene/community of "boot into game" for current CPUs? (programming.dev)

I'm looking up for communities or scenes whose purpose is making games that you play from bootup. Not necessarily boot sector games (stuff that has to fit in 512 bytes), but things that would behave much like cartridges in old consoles, where the hardware boots straight into the game.

Put another way, games that "are the OS", either for x86 or ARM. My search engine-fu didn't manage to find anything other than boot sector games and several Batocera guides.

Would a game that is essentially a micro Linux distro count? I feel that should be pretty doable as a bootable USB stick or CD.

If you did it that way you'd have to bundle the Linux kernel plus graphics drivers at a minimum. But I wonder how much of the OS you could avoid having. Certainly you wouldn't need a Desktop Environment. I wonder if you would need something like X or Wayland or if you could get away without that (to run games built in a normal-ish userspace way). I guess finding the minimal environment for SDL would be a good starting point. That sounds like an interesting exercise for sure.

Although something like that probably isn't as pure as you're looking for, it would be pretty cool to do anyway. Maybe we should start a club.

Yeah, it's something I've been thinking about, either write a minimal kernel or use Linux's as a starting point and see what's possible from there. I think starting out with ARM (raspberry pi) might be easier, thanks to its fixed base hardware
