The Legend of Zelda: Majora's Mask 3D Cheats

Music at night
Go to Snowhead and beat the temple. Now make it night and head to the
Goron Shrine. When you come out, you will hear the overworld music even
though it's night time! In fact, as long as you stay on Snowhead, when
dawn comes the music will continue to play as the DAWN OF THE whateverth
DAY message appears.
