impossible. you have to do levels to unlock miis.
Do cups. I think you unlock them by doing the 150cc on it.
You get it by doing the Mirror Special Cup.
no
there is no way
no. D:
Yes since you unlock toadette, birdo, and the Magikrusier by doing enough time trials. See if you can find out how to get the other ones :D!
to unlock everything you can either unlock characters/items by playing expiedition mode or doing challenge mode which you can unlock by defeating Bowser Jr through many journeys in super sluggers
the only character that you could unlock by playing super Mario galaxy 1 is rosalina because she was only in super Mario galaxy 1 and now 2
you have to get a hack, look on youtube for it
well, look in the directions and i beat the game without doing that
To unlock karts and characters, you can get them by doing Grand Prixs or Time Trials, or winning lots of wifi races. Or, you can simply play the game alot.
u would keep doing different levels over and over again
