The "I Am The C-64" tutorial programs for the Commodore 64 have anti-piracy disk copy protection, despite being written in BASIC, and it's enough to thwart simple "fast" disk copiers. We go through the steps of making a copy of the disk on a real 1541 and KAO 5.25" floppy disk with the help of Maverick's disk nybbler, and then go a step further and "de-protect" the program so a nybbler is no longer necessary.
