[Coco] Any tips for getting OS-9 or Nitros-09 running in anemulator?

[John Guin]

Fantastic!  I can now boot Nitros-09's 40 track disks in MESS.

Thanks,
John

PS:  there's a bug in someone's email system here.  My original mail I sent
had a space between "an" and "emulator" but it has since been stripped.

Odd.

I know a trick for MESS (only becuase I wrote it :). Change the .dsk
extension to .os9. This will cause MESS to read LSN 0 to determine the
geometry of the disk image.
