i hope no because when i go online on mario kart ds all the people are fast and its not fair! i hope it doesnt happen with mario kart wii

You might have already known but Yahoo always has videogame cheats. You could check on Yahoo Games if anything there is useful to you.

no, they took snaking out of the game. that's what people in DS do. it's not a race with the DS, it's who can snake the best. on the wii, they realized what was going on and quickly took it out. so no, there are some ways to cheat in the Wii game, but they are as known as "snaking" on the DS.

No there is no way to run hacks online like on Mario Kart DS, if you see people saying they saw someone hacking online its 99.9% of the time lag....

Hint: Avoiding POWs
Getting attacked with a POW can be a bummer, but if you flick upward your steering wheel or Wii remote, you can avoid it. You will spin around, and you will lose your currently-equipped item, but you won't slow down and will avoid the devastating result of being struck with a POW.
