Oh it's real. Apparently that blurb was copypasta from
here.
It's always fun to try and find where pirate outfits lift their text from. I have a PS2 silver of Hyper Street Fighter II Turbo whose back cover is lifted straight off an Amazon.com review, and a Metal Slug 3 that does the same thing.
Believe it or not the manual actually refers to the storyline of Contra Force, which is funny since a lot of pirate GBA manuals are just a bunch of cut and paste nonsense that has little or nothing to do with the actual game. I also got in Kirby Red Diamond aka Kirby's Star Red Diamond, it's manual is about 5 sentences of storyline copy that repeats itself for 6 pages.
Edit...Thought something was familiar... see the intro and storyline paragraphs on the page I linked to above? The manual is straight copied from that with a screenshot on each page, even using a screen from both Contra and Super C.
