Listed as "challenges" in the menu the Wii version of Mega Man 9 comes equipped with all the achievements that the 360 version will have. I would assume this will be true for the PS3 version as well. No, you don't get your Gamer points for them, but the game does come equipped with some awesome online leaderboards, so if the lack of achievements was what stopped you from getting the Wii version, go buy it now, unless the only reason you care about the achievements is your score.
