Huh... I thought Linux actually required MMUs. I was under the impression it'd never run on these old consoles because of that. Learned something new today.
> A QEMU fork that emulates enough of the MegaDrive and the EverDrive to play with this without the real hardware is included.
That's seriously impressive.

There have been variants of the kernel around for some time that can run on microcontrollers without an MMU (mainly uCLinux).
There was no MMU in the Macintosh Classic/SE lineup which used the 68k as a CPU, but they still support the microcontroller targeted distros like uClinux. Unfortunately the tight integration with the ToolBox ROM makes it a fairly Herculean task. Microsoft bizarrely enough released Xenix for the Apple LISA as well, but that's more of a historic oddity.
Similarly, Basilisk II is a very worthy emulator for Mac 68k emulation so there's a lot to draw on for QEMU and the like.
