I rewatched an episode of X-Play today where they review Mario Kart DS and it showed the unlockable characters. So I've seen them now. I must not have took note of this the first time, although the first time I watched it I hadn't gotten Mario Kart DS yet b/c it Christmas hadn't come yet. And I saw some of the unlockable stages. They looked interesting. I need to get to it.
well if you noticed they didnt include the N64 tracks with the glitched shortcuts.. rainbow road was one of them, even though it was nicely designed
Or the classic, get in 8th on the first attempt, be behind Bowser or DK.
Get the turbo boost, launch off their back w/ a jump, and skip half the level. I got a 1:49 time for lap one. ๐
