Hi all,

I received tons of .D64 images of older C64 midi Software.
Right now Im trying out Musicalc written by Waveform in 1983.

I tried booting from the image no go it loads about halfway and just stops
and I thought that Musicalc may be copy protected because some copy protection 
checks and if a copy will probably stop, etc.

 I checked Fast Hackem and Maverick parameters and they don't even list 
anything under Musicalc, nothing. (parms).

Would anyone know anything about Waveform protection or a way to try editing 
disk sectors etc?

 Again I don't have the original of this its just a .d64 image, and BTW
I use CBM Command to write the disk image back to a real 1541 formatted disk.

I do have the Maverick V5.4 with a good disk editor if anybody knows how to 
edit Waveform protection (For my own backups only). :D

Musicalc has a timer that takes around 2 minutes to load with this .d64 image 
it only gets as far as 1min 40 seconds and it just stops completely.
I recognize this as being protected because some protection if it detects the 
disk is a copy then it will do this and stops like a mule.

Would a disk scan help anybody to determine what is going on?

When it comes though to disk editors I dunno Im willing to try though, of 
course I have the original .d64 and can make another floppy of this, or just 
use a copy of course if I goof it up, etc.
