One of the most fantastic websites on the entire Internet, Pix's Origin Adventures, has posted a nice high res scan of the game manual for the Super Famicom version of Wing Commander 1. This edition is more than simply Claw Marks translated into Japanese however, and the booklet gets tons of bonus art alongside reformatted text. Some drawings are brand new, and others are colorizations of art used in the English documentation. We've seen the front and back covers recently, but check out the whole thing here (27 meg PDF).
Pix's Origin Adventures, my favorite blog, now has the SFC WC1 manual for download. It's full of art you've never seen.
