Mario & Sonic at the Olympic Games Cheats

I only borrowed the one for the Wii, so I don't really know, but I think that if you get gold medals in all events with one character, you earn that character's crown.

100m Freestyle
To become first in basicly every time you play, use Sonic or Shadow in my view. They have very basic shapes. (Not like Blaze with the figure of 8) Sonic is the Left to Right shape. Rub really fast like in the running. Shadow is up and down. That's not hard. Just turn the Nintendo DS so it's left to right. Rub really fast etc.

10m Platform
This is quite hard for some people but for me its really easy. To get max height when jumping off the board, press and hold down 'A' for about 2 seconds then release. As soon as the button prompts come up, don't bother looking to see which one is 'A' and which one is 'B'. Just focus on the screen and make it so your right hand presses the very right button first then the bottom one and repeat till you have done all the prompts. Do this for each set of prompts. Just memorise where each button is.
X
Y A
B
Then when you have to press 'A' at the right timing to do a perfect dive, focus on the screen and when your character is about facing downward, press the very right button to do a perfect dive at about 00.02 Degrees. Using this tip/cheat/hint/help you should be getting almost perfect 10's or 9.50's

When you do perfect for all of the rounds( never ever even slighly messing up) you wil nit have 10 but 15 round and then 20 and then 25 and I think it goes to 30. I never made it past 25

Enter a track event not 400m hurdles and pick Luigi if Sonic is in the race you can beat him the final sprint you can beat him is you do the final sprint you need to be neck and neck it is hard but you can do it!

P.S good luck

These are songs that you will unlock by doing all of the following. ( pretty much by beating minigames! )
