Essentially the way that it works is you beat a track with the same loadout as the Nintendo ghost for that track as fast as possible (Ex: Nin☆Elena, Nin☆Yuya, etc).

However, it has to be the exact loadout. No Azure Rollers if it says Rollers, no Gold Glider if it says Standard Glider, no Daisy if it says Yoshi, etc.

I've given it a try, and it's pretty fun. I would love to add it to a sr.c leaderboard and be able to compete against other people!

Thanks!
