Oh baby, start revving them engines! Sure, it's box art...but it contains news! And hell it's Mario Kart!
Here's a kleenex! Start drooling!
Something's to note on this...
1. The Mobile GB logo. Well at least ranking and ghost data will be able to be transferred. Not too shabby. Unfortunately, as of right now...Only in Japan.
2. It's not called Mario Kart Super Circuit in Japan.
3. 1 cart = 4 players! How much is available on one cart is still unknown. According to what we do know, you'll only get to race on one course (ala F-Zero)
