I actually quite enjoyed tbe oldskool copy protection. Some of them were so briliantly funny you just couldn't help laughing!
I actually hated LA for excluding copy protection on monkey island CD versions ~_~
Actually that'd be "manual protection
". A "copy protection" consists of erroneous data, foreign-format sectors or other purposely introduced errors that will make a floppy drive or CD reader choke on the disc if it's not being read via the built-in access routines of the exe wrapper (or custom file system drivers). Most old copy protections used foreign-format sectors or odd timings, and those protections weren't possible to do on PC since the standard floppy controller (still) doesn't allow custom timings or other oddities (which is also why an Amiga drive can read a PC disk, but not the other way around). Hence, PC versions of games were forced to use "manual protections", there was no way of blocking a diskcopy tool from backing up the disk.
So to sum things up, if you can copy a disk using standard disk tools such as diskcopy (on PC) or XCopy (on Amiga) or if you can copy a CD using only Nero or Easy CD Creator, the media is NOT copyprotected. No matter if the program asks for information from the manual.
There, hope that clears things up.
And I agree, the LucasArts manual protections were definitely the most well-designed ones in terms of humor and ease of use. Most other games had an annoying "please enter word X of row Y on page Z" type protections, which were totally devoid of humor and just plain annoying.
