Or is that the Minako Code? Either way, Zi-O episode 3 had a particularly nice reference:
I’ve seen several people, including whoever wrote the episode’s page on the KR wiki, completely mess this up.
The Code is “up up down down left right left right B A”. This note is “down down up up right left right left, then press all keys at once.”
I’ve seen people say this note has the Code as-is, I’ve seen them say it’s got the left and right inputs reversed… it’s almost as bad as thinking “start” is part of the Code proper.
