Not quite as retro as perhaps intended but I have a wide variety of PS1 manuals, front covers and rear inlays. I keep most of them on one side so if I get another copy for my ebay store and its incomplete I can fill it.
However its not all that often I actually use them so if anyone is short any covers or inlays for PS1 stuff , drop me a PM and I might be able to help.
I might not have the one your after but what y'all got to lose!
