I love them evil old anti-copy schemes.
The twist here is that every protected disk is unique, and the uniqueness is a side effect of writing to the disk normally. This is the first scheme I hear about that’s like this.
If you like that kind of stuff, have a look at 4am crack reports like this one for the game Gumball on Apple II.
Cool. Definitely was a lot of work!
I can’t say I’m a fan of the 40 column format though. I understand they want to be readable on that platform, but still.
Neat enough I just submitted 4am crack at archive.org as a story.
Do people not use “disk”?
I was taught in school disc = optical, disk = magnetic or other
Here (Australia) “disc” has been almost exclusively used, though that’s started to change with American usages becoming more common.
Disc for media that’s literally a disc (like a cdrom).
Disk for media where the disc is hidden within a non-disc container (floppy, hard disk).
