Onefile-demo with protection?!

Hi all,

here is a tricky one. A friend of mine tried to analyze a one-file-demo back in the late 80s, because he was impressed with the effects; it could have been a crack intro as well.
Unfortunately the only thing he remembers is that the program formatted the disk, after he had changed something in the code (he tried to run it block-wise, to see what each part was doing), so apparently it had some sort of very nifty protection against nosy rippers. :-)
Anyone ever encountered something like this?

Never really cared to investigate. Maybe someone else cares to check :)


Yeah, I had the same experience with the same tooldisk. It was Magic Disk 64, Sonderausgabe 3:

It wasn't the FC3 fastloader which "killed" the disk though. But if you had a load error, it would quick-format the disk because of the wrong end-addy in the zeropage.
