Brutal Deluxe Software has published the first three videos in a their Apple II Cracking Senses series. The video series is designed to teach the current generation of Apple ][ fans what it takes to crack old software from the 1980’s game by game. While much of this software is long abandoned through either non-existence of the company that made it or through the loss of the original code by the author, it is an interesting insight into what these publishers and authors did to prevent or at least slow down people from copying their software.

UPDATE: Antoine Vignau has posted three more videos to the series. He has also posted a sample unprotected disk for those who wish to try their own hand at the cracking.
