|  Copy Protection -->
You have an advantage in that you have an original to work with. It's easier to detect the original protection, and recreate it, than it is to work backward (put the protection on when you don't know where it was to start with) like I am doing with GEOS +4.
There are a few copy protection cracking programs on funet.fi for the Plus/4. Also if you have a good understanding of English (as you seem to do when you write here) you might check out the "Inside Commodore DOS" .pdf that is available on the 'net. It's a huge .pdf but it has program listings for detecting protections on diskette, and how to duplicate them.
If the disk is for 1551 only (see the documentation) then you'll have a slightly harder time recreating it. If the disk works with a 1541 (or 1541-II or 1571) then you can use the .pdf without any further headaches.
The "Inside Commodore DOS" .pdf can be found on sta.c64.org (Star Commander homepage), or I've posted links in this forum before (search for "Inside Commodore DOS" in the searchbox above).
