I love that they wrote a tool to automate cracking. I'd be curious to know more about it, like specifically what kinds of protection it could break. IIRC a lot of copy protection on the Apple ][ was pretty straightforward, they'd just change the marker bytes for where sectors began to something nonstandard. I imagine that's pretty easy to automatically reverse. But a disc with something weird like spiral tracking or software with a deeply obfuscated "look up a word in the manual" system must be harder to crack.
