According to the dev, the biggest challenge was that the Motorola 68000 lacks a Memory Management Unit. So, a standard Linux setup with virtual memory would not work. Luckily, Linux still supports m68k systems without an MMU by using the uClinux/NOMMU option and a flat memory model.

I was honestly expecting it to be weirder hardware, turns out it's a configuration the kernel already supports. Still neat, but somehow a bit of a letdown.

The DSP stuff is cool though, that's sufficiently weird for me.
