This address is effectively the high byte of $0DD3 on the overworld and should not be touched there, though in levels it is unused. It is also referenced once as the low byte of $0DD5, though its value isn't used there.
Cleared on reset and titlescreen load, and when Mario starts walking on an overworld path. |

Should be 00 |
An address that is expected to be #$00 throughout the entire game. $7E:0DD6 (current player) is sometimes used in 16bit mode, so using this address for different purposes is a bad idea. |

Misc. |
Back-up of the music register. Gets its value from the level music table at $05:84DB.
Bit 7 of this address is set when the player has a star powerup or presses a P-switch; when this is cleared again, the music ends.
This address is also set to #$FF when the level ends, either by beating it or by dying.
Bit 6 is similar but is used to not reupload all music. This is used when changing from the Mario start screen to the level game mode. |
