Great, it's such a thrill to complete a formerly loose game with a manual.  This is how my R-Type, Dead Moon, and Splatterhouse got completed (to my satisfaction anyhow).  As long as the manual has all of the pages still, or even just the cover I am happy.  My Y's and R-Type have writing in them but I don't mind.  My Neutopia II manual has well rounded corners and lot of wear and bends, but again, I don't mind (and I still treasure it).
