Mario & Sonic at the Olympic Winter Games Cheats

You've got the 20 characters that are put into the game, Sonic, Mario, Silver, Bowser Jr etc. You can unlock each of their costumes in the Boutique. These can be put onto your Mii and can be bought for 300 stars each.

So by 5 gold/1st medals, you could unlock a costume with Shadow by getting 5 gold/1st:

Dream Snowboard Cross
Moguls
Dream Alpine
Curling
Speed Skating 500m

And there would be a costume with Shadow, if you get it by now.

By VIP, I mean Big or Birdo. You might get mail from them saying that they'll be at a certain Dream event cheering you on. If you spot them there, press '(-)' for a bonus 100 stars and their suit.

If you still don't get it, you might get mail from Birdo saying that she'll be at the Dream Curling event cheering you on. She could be on the side of the alley, or by the ice statue penguins at the top of the alley. Something like that.

You can unlock special costumes for Miis while playing. Mii Character Costumes not only change your Miis appearance, but they also adjust the Mii's Statlines to match the character. Playable Character Costumes are unlocked simply by playing a lot of different events with the respective characters. However, there are some special costumes that can only be unlocked via special means.

If you've just got this game and hoping for a few Dream Events, here's how to unlock them. Nearly all of them are on Festival Mode.

To unlock the emblems in the game, achieve the following accomplishments.
