@foone 40 years ago, I cracked EasyWriter for PC-DOS using DEBUG.COM by replacing one instruction with NOPs. The copy protection was of the classic "read a sector on the floppy that shouldn't exist" flavor (don't remember if it was tricksy formatting or a physical hole in the disk) but I just stepped through the initialization until I saw the INT 13 and I could see what it was doing.

@foone Why did I immediately think of a particular Windows volume license key?

@foone I had completely forgotten about HD-DVD until you reminded me. Hopefully I can forget again soon.

@foone Well, but so can empty memory...

@foone No HP 200LX for you!
