I will test the new disk images with VCC and a physical CoCo and send them to the archive if they work as expected. I believe MAME no longer supports the headerless .os9 disk format. I have not compiled MAME version 0.189 yet, so I do not know if that has another issue or not.

By the way, I just looked at the readme in the .zip file and it states "Rename the virtual disks 
from .dsk to .os9 to use with MESS."
