Well, I think (I may be wrong though, I am not very familiar to Macs),
that such a particular thing gets easier when compared to a QL or another
emulator. Namely, I got an impression that Mac programs are mostly (or
100%) system clean. So you don't need to emulate the hardware, just the
problem is to interface the Mac application to the Atari operating system
(mostly GEMDOS and GEM itself). Both things (OSes) look quite similar,
don't know about eventual differences in internals. I heard Macs use traps
to call the system (some weird way, though), so if, by a strange
coincidence, these traps are not the same as used by Atari, things start
even more nice.
But a Mac developer documentation is definitely needed to think about such
a project.
BTW. I've seen your QL emulator, but I can't get it to work. Perhaps
because I am lacking QL knowledge, but it looks strange anyways (why the
hell the screen is white on the left, and red on the right??).
