Menu Codes are secret phrases that may be entered in place of a name when creating a new save file. Entering one alters the gameplay of the save file. Multiple codes may be enabled at the same time.

After entering a code at least once, pressing HELP on a blank file on the file select screen will display a menu showing all previously entered codes, allowing them to be toggled on or off.

Menu codes do not need to be found in-game to be used.
