[Coco] CTUNES.DSK

[Robert Gault]

OK, I finally got the ctune disks to work. 
You can see them almost working with emulators or a real CoCo as DOS gives the message LOADING then OS and freezes. 
You can get the disks to work only with a CoCoSDC system. I have SDCDOS 1.6 on my CoCo3. Both the ctune versions 4 and 5 will start when the sdc explorer program points to the .dsk images and the ENTER key is hit. However since I don't have the psg hardware, I can't play any music. 
When you look at the disks, there is no directory data on track17 but there is a short binary program on track34 starting with OS so the DOS command will run the program in track34. That starts the binary program which begins on the first track. 
The zippster's site explains the hardware required to run the ctune program but does not describe the format on the .dsk image.

The .dsk images on that site are not normal images. They are not OS-9 or Basic disks, do not have directories or other .dsk structures, and look more like .bin files.

First I try to list it in RSDOS results below.

DIR

DRIVE=0  FREE=0

I don,t see anything in OS-9 ether.

So I go back to BASIC and with CTUNES.dsk in the default drive type DOS  results below.

DOS
{screen clears}
LOADING ...

:) Yay something is happening.
I get called for supper.

I get back 40 minutes later and turn on the monitor.
still
LOADING ...

:( Sh!!t that's not working.

So now I am at a loss.
Do I need a second disk in drive 1 and where do I get that ?
