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

[Robert Gault]

It does not matter whether your version of Disk Basic can use 40 track 
or only 35 track disks. If you are having trouble with MESS, change the 
disk image extension from .dsk to .os9 and in most cases the disk will 
boot assuming it is a bootable os9 image.
