I remember quite awhile ago, I made a thread about how back in the "good old" days, used to make whatever shit they could in a game manual, no matter how ridiculous it was, due to the lack of in-game plots in most of these games.
Of course, Konami of America is the no.1 culprit. Anyone who picks up any manual from their NES library will know how awful they were, often contradicting the original designer's intentions (the original Metal Gear being the perfect example of this) and at the same time adding a retarded sense of humor that would be insulting to anyone over the ages of four.
Of course, I've also heard that Capcom USA's manuals weren't very good either (although nowhere near as bad as KoA). I heard many accusation from Street Fighter and Mega Man fans regarding the inconsistent characterizations between the original Japanese canon and Capcom USA's literature regarding the series. I don't know about Street Fighter and Mega Man stuff, but I do own a copy of Biohazard: Director's Cut and I'm surprised that the character profiles in there are hardly parallel to what Capcom USA included in the US manual. (such as Kenneth's position in STARS. He's supposed to be a recon specialist, no mention of him being a chemist).
Also, Sega seems to have written some inconsistent translations too in their past (as I've seen in the Sonic and Shinobi games).
I'll provide some excerpts if anyone is interested.
