why is the qualification for a run of this game 150cc? or at least why can't there be category's for 50 and 100 cc?

Because it has always been like this for other Mario Kart games, I suppose ? (And because it's way faster, too)

Anyway, I'll suggest that we add 100cc, 50cc and Mirror to meme leaderboards (the_illuminati created a thread here http://www.speedrun.com/mk7/thread/n9wls , but we only have 1 category so far), as that's really unlikely for these to be added as main categories.

thank you... was just wondering since its a bit off a cap for more diverse leader board and i thought mario kart 7/8 might be a bit more diverse. PS it took me forever to pb with 150cc so i wanted to ask... :D
