Okay, we got this page. Exactly which of the 4th generation names are, hands-down, official romanizations and not simply guesswork? While it would be easy to assume that all the names under "Trademarked romaji" are official, they have been changed around a lot, and there's still stuff like "Mōkazaru" there, which isn't official at all (Moukazaru is). Also, I was pretty sure Hayashigame was official, Pokewiki certainly claims it is.
So yeah, basically, which romanizations do we know are trademarked and official?
