(re: KQ III and IV)
I have the CD version and it came with an insert (I guess you could call it a square manual!) But… the insert doesn’t have any of the copy protection info in it, just installation instructions. I got this at a thrift store; I always assumed some sort of manual must have been packaged with it originally. Do you have a CD insert that also includes copy protection stuff?
The long skinny manual I got with the Mac version when the game first came out.
