Here's the 150cc Mushroom Cup in Mario Kart DS. I manage to get a triple star rank with Mario on the Standard Mario Kart. As usual, the first cup isn't too hard, but you'll really need to master snaking to be able to get a triple star ranking in the harder difficulties.

Tracks:

Figure8 Circuit
Yoshi Falls (reappears in Mario Kart Wii)
Cheep Cheep Beach (reappears in Mario Kart 8)
Luigi's Mansion (reappears in Mario Kart 7)
