Menu Codes are secret phrases that may be entered when naming a new save file. Upon entering a menu code successfully, a sound effect will play. Each menu code alters the gameplay of the save file. Multiple codes may be enabled at the same time. After inputting codes, the player can then input a valid name for the save file and play with the modified save file.
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 when creating a new save file.
Menu codes do not need to be found in-game to be used.
