That's a nice solution, but it's not "boot proof" right? :-)
nope... not bullet proof at all. a lot of software has custom track loaders and its not going to work with many. A lot of those multi-disk adventure games will work.
Heck, a lot of those old ADFs I have on my minimig won't even make use of more than one floppy drive, and as you may know, Minimig (with ARM) has 4 virtual floppy slots

You might be better off looking into one of those hardware floppy drive emulators. I don't know much about them or which is the best.
I did it the lazy way with my A1200... I downloaded a huge torrent of whdload games all ready to go...
That would assume you have a HD though...
My minimig only has 3.5mb RAM and whdload works very well. The only drawback to running it on a 68000 is that you can't exit many games and you have to reboot...
