Are the .dc disk images just disk copy 4.2 images? I've been trying to get them working with my FloppyEmu and it does not seem to like them. I tried copying them to my MDD running 9.2.2 and using DiskCopy 6 to open them and they fail to even open the disk images. I tried to convert them to the .dsk format but when I try to boot from them they do not appear to work. FloppyEmu will allow me to select the .dsk, but appears to crash or otherwise reject the disk image when the Lisa tries to read from it.
I also attempted to use the ProFile disk image with my Cameo/Aphid and it also refuses to boot from the hard drive when that .image file is selected. Would love to try this out, but as someone who's never done anything with early Ataris, or Lisas for that matter, I'm at a disadvantage. Is my only option physical floppies created using DiskCopy 4.2 on an older Mac. I do have some Macs that might work, but it feels like if we can provide a solution that uses FloppyEmu, many of people will benefit as it provides an option for people without working 400/800k floppy disks / drives.
