FYI you can create disks and transfer files using a program called HFVExplorer on Windows. It works but because the MiST has the disks read-only, it will fail to mount newly created images. To avoid that you can either open the disk once in an emulator (so desktop files are added to it) or copy and empty an existing working disk in the HFV program.
What I'm finding a bit difficult is transferring the higher-density floppies (1.44 MB) because I have to extract all files in an emulator then recompress at 800 kb archives I can put in disks. I'll get around to it once I find a compatible Stuffit version...
Oh and this isnt a complaint.
the above is exactly what I had to do to get files into (or out from) my old Mac SE. So I'd say the MiST core is working exactly as the real thing
