I think so, you just need a SMG2 save file.
Rosalina is not in Super Mario Kart. She is in Mario Kart Wii.
No she is not, but she is in Super Mario Galaxy and Mario Kart Wii.
In super Mario galaxy (where Rosalina comes from) Rosalina looks after the stars (Lumas). So a luma revolves around her in Mario kart wii.
The easiest way to get Rosalina in Mario Kart Wii is to buy Super Mario Galaxy and make a save file in the game. The next time you play Mario Kart Wii, you should have unlocked Rosalina.
No, you have to have a Super Mario Galaxy save file.
there is no baby rosalina in Mario kart.
The "star" that floats next to Rosalina is called a 'Luma' the Lumas are from Super Mario Galaxy. And Super Mario Galaxy
Rosalina first appeared in Super Mario Galaxy on the Wii.
Here is a cheat just for you... If you have a super Mario galaxy file, you automatically unlock Rosalina for play in Mario kart!
You need a copy of Super Mario Galaxy 1. Play it for a while ,then Play Mario Kart then it will say you have a gift From Super Mario Galaxy. then it will say you can play as Rosalina.
No Rosalina doesn't. But the stars are like her kids... kinda
