We have had a sneak preview of the completed version of Mario Kart Advance of the Game Boy Advance and we noticed something you might find interesting.

At the boot-up screen, the Game Boy Mobile Adapter logo is displayed. A quick dig around in the options menu reveals the ability to input a telephone number of your choice. We are not quite sure what this connectivity will enable, and Nintendo refused to tell us. Real-time racing, anyone?

It is also unclear whether or not the European version of the game will include Mobile Adapter support.

More in the coming weeks.
