Transfer of tracks
no. it really stinks. 
i think it is because they are different platforms and the data systems are different, along with the format of the map. although i don't know that for sure. 
i don't think it would be possible anyway. anyway, no. it might also be that the physics are different because i am sure they are. i have ds and pc and i would also like to do that. but you can't

I bought the DS version and was disappointed that you can't color things in, so I planned on returning that copy and buying the Wii or PC version. Instead, if I were to keep my copy and buy the Wii or PC one, would I be able to send the tracks from my DS copy to the Wii or PC copy and color them there?
