The Commodore 64 was a very important machine to many current computer users. That is why I am glad that projects like the The C64 Preservation Project exists. Their goal is to archive pristine versions of original Commodore 64 software, including copy protection. A secondary goal and benefit of this will be to catalog and document all the different copy protection methods used. This information will be used to improve emulation, as well as allow remastering of the software onto new disks for you to enjoy on the real thing.
Naturally this is not an easy task, so stop by and see what you can do to help.
