I couldn't find Black Matrix, but there's something called Black that says it's made by Matrix, I assume that's it, but there was a blunder getting it entered into the database? I'm also wondering if we should have two listings for it, since there's two very different covers for the manual. I own both variations now, so it would be nice to have them listed separately, but it isn't absolutely necessary. I do need a good entry to check off at least one of 'em though!
P.S.:
While I was in that section, I noticed that Soldnerschild is listed as Soldier's Child.
