Here is a copy of Daggorpatch. This was written by Burke and Burke to copy the ROM to be played from disk. It also changed ZLOAD and ZSAVE to use the disk also.

The license is shareware. If you keep it you must send $5.00 to:
Serotonin Software
P.O. Box 1045
Woodinville, WA USA 98072-1045

This information is really old. I would send a letter first to make sure it is still active.
