trying to get Rosalina..... u need a stupid number of WFC wins (not gonna happen there are some amazing racers!) or star ranking on mirror class (hate that one!) or to have a super mario save file...
ok the thing is i dont have super mario galaxy so am gonna probably buy it on ebay... but this is gonna sound dumb...whats a save file? like do u play a bit and then save the game as it is. put the mario kart disc in...and it will say u have unlocked rosalina?
im not a gamer and havent bothered putting an SD card or anything into the console.... so....will it be a save file.
