By getting "The Homebrew Channel."
Yes, you cannot make your own tracks on Mario Kart Wii without hacking. Doing so requires the use of homebrew for the Wii.
Yes you can using homebrew for more info search homebrew on google and for tut go to youtube type Wii homebrew 2010
With the Twilight Hack and the Homebrew Channel, It's possible.
you have to get the homebrew chanel then put in the codes
you need the homebrew channel
If you soft-mod your wii (setting up the homebrew channel and/or other non-nintendo licensed content) you will be able to add hexadecimals, commonly referred to as "gecko codes", to the loaded version of your wii game. For instance, you could add hexadecimals to your Mario Kart Wii game (RMCP, RMCU and RMCJ are the game codes for Europe, America and Japanese versions respectively), which tell the game that all players always have infinite starmen. The game will load this hexadecimal, thus it will be true.
No. But what you probably want to do with that ability is probably available anyway...
Not without homebrew.
Homebrew channel is the safest way to hack stuff. Although there haven't been very many cases about it bricking your wii, there is still a risk.
