My favorite copy protection was from starflight 2. There massive galatic colored maps. You had this little square gizmo and had to align it to various grid locations. Then count the many colored stars that the game ask.
If you failed there was a chance that the space police came after you and well game over.. hehehe.
Back then not many people had color printers.. I don't recall any scanners ether...
I still have that game.. I wish it was updated... and improved with todays graphics\sound effects... that would be an awesome game if they stay true to the story.
