Mario Kart: Second Circuit, formerly Mario Kart DS N64 Circuit, is a hack of Mario Kart DS that aims to be a spiritual sequel to Mario Kart: Super Circuit on GBA, started in 2014.

When finished, it is planned to have 16 brand new courses, as well as all 16 courses from Mario Kart 64, similarly to MKSC's Extra Tracks.
