I've had some success!
Using the HXCFloppyEmulator tool I can load the raw track files by just selecting the first track. I can then export it to a variety of different formats.
I loaded one disk that is not a booter (not sure if it had copy protection) and exported it as a .img. It loaded fine and I could read the contents in the emulator within DOS.
I loaded another one, exported it to .img, and nothing. Then I exported the same raw stream as MFM and that one booted up just fine!
I have third raw stream I can't get to load no matter what I try.
I am happy I am making progress... anything I can do to make the results more consistent?
