You need to install the Mario Kart Channel.

When you are in the Mario Kart Wii game, go to the "Select License" screen.

Click on the "Settings" icon in the top right corner.

Select "Mario Kart Channel.

Well, I'm pretty sure you could use the nunchuck.

It's from a different region, so it won't work at all unless you either:
A) Buy a european Wii
or
B) Mod your Wii to free up the regions.
North America and Japan (as well as some other random places) use NTSC format, while Europe (and other random places) use PAL format. You can't play PAL on NTSC and vice-versa.

Something like a microwave can disrupt the signal then it reconnects automaticly and switches.

there may be a scratch on your disk. have you tried wiki/yahoo answers

if you have upgraded your software on your wii, your freeloader won't work anymore. Mario carts is written in a way to stop people using programs such as freeloader. Its something called signed trucha, other people will not more. You could try buying a UK mario cart on ebay and trying that. Otherwise, looking into getting it mod chipped to overcome the region barriers. But always buy original games for it

look at the brass connectors, are they dirty? that could cause a problem

I’m not 100% if you can create customizable karts, but I think it’s probably unlikely!
