List of Mario & Luigi: Superstar Saga glitches

These are the glitches found in Mario & Luigi: Superstar Saga.

High Jump Glitch
In this glitch, Mario and Luigi will disappear from the screen and will never appear again until the player resets the game. To do this, the player must first defeat Fawful in Bowser's Castle and then save in the next room. After that, the player should have Mario in front of Luigi, and Luigi behind Mario. Next, the player should make Mario into Mini-Mario by having Luigi hit him with the hammer. Once Mario is in his mini form, the player should go back to where Fawful was fought, and walk to the bottom right corner. Once at the corner, the player should have Luigi perform a High Jump, but have Mini-Mario hit him by jumping while he's in the air. If performed correctly, Mario and Luigi should disappear, but the music will still play. Mario and Luigi will never reappear, all the player can do is turn off the game.

Unfitting Music
If the player has Mario turn into Mini-Mario, by having Luigi hit him with his hammer, and walk into an area where the music changes, the player should notice that the music didn't change. Even though this happens with most areas, it doesn't happen with all places. This can also result in comical effects, such as the under ground theme playing in Beanbean Castle Town. Having Mini-Mario entering pipes always results in this glitch. However, this will not work upon exiting the warp pipe in Joke's End.

Additionally, after Luigi is taken by the crane in Woohoo Hooniversity, if Mario hits the Save Album while moving left, and continues to hold left, he will walk a short distance down the nearby staircase. If the player Saves and Quits, then reload the game save, there should be no music. However, fighting one of the nearby enemies will cause the background music to change to the save-file music. The music will revert to normal if the player does not fight an enemy before saving Luigi, otherwise it will revert back after they save again, after the cutscene with Cackletta, or upon leaving the Hooniversity.

It is possible that Nintendo purposely put this in the game.

Bowletta Glitch
To trigger this glitch, the player should use the advanced version of Cyclone Bros. during the Bowletta fight. If she gets Dizzy, the player should then "defeat" her quickly. She will then act out the entire cut scene that follows while still being dizzy.

Endless slow Cackletta music
Similar to the above, this glitch is caused during the Bowletta fight. To trigger this, Bowletta's health must be low when she becomes Dark Bowletta and starts throwing stars at the player. If the player throws enough back at her to defeat her, but also gets defeated him/herself, the player will see a mixed scene of Game Over and Bowletta sucking them in. Instead of switching to Bowletta's stomach, the player will come to a black screen, with the eerie tone of Cackletta's slow music being looped until the player resets the game.

Disappearing Sprites
Much like the "High Jump Glitch", this glitch will make all sprites from the screen vanish. To do it, the player needs to have the advanced version of the Cyclone Bros.. When finding an enemy, the player needs to fight it. The should use the Cyclone Bros. to make one of the enemies dizzy, then they should kill the enemy right after. Shortly after wards, all sprites (e.g. Mario, Luigi, remaining enemies, etc.) will vanish. The music will still be playing, but all the player can do from there is to reset the game.

Note: This glitch will not always work; it works mostly in Bowser's Castle.
