List of Mario & Luigi: Superstar Saga glitches

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

This glitch can be activated with the last Popple battle (with Birdo) and the Jojora battle. The player must first hurt either Popple or Jojora's Friends enough so that a Fire Bros. attack wouldn't kill it, but the burns will. Second, the player must Burn either Popple or Jojora's friend with Fire Bros., the advanced version being easier to burn. The player then just has to wait until Popple or Jojora's friend dies from their wounds. If they use an attack that needs to be countere, the player needs to let it hit them. Once the victim dies, their partner will act as if nothing had happened. Birdo will attack normally instead of getting angry, and if she uses her egg attack, a "ghost" sprite of Popple will appear onscreen but it can't be damaged nor can it attack. Jojora will continue to use her wand move, and if the player knocks it away, the game will freeze once Mario and Luigi attacks nothing.

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.

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.

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.

While Luigi is going across the bridge to Piranha Bean, if you try to fall off just as you reach Piranha Bean, Luigi will fall off, the and the plant eats the bean, but will not see Luigi. This results in just the plant standing there, and the player will have to turn their game off.

In the beach area, where Luigi turns into a surf board, if the player steers Luigi onto a nearby shore into a Bob-omb enemy, Luigi will be normal during the battle. Also, if the player defeats the enemies, or opens the suitcase when in midair, the game will freeze.

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.

Right after the player acquires hammers, he/she should make Mario the leader. The bros. must go up to a water fountain and make Mario ingest water. Luigi should then hammer Mario until he runs out. When Mario is getting angry at Luigi, he can fly up. Other times, he can get angry at the fountain for some apparent reason that one may never know why. Note that this glitch stops working once the bros. learn the hammer techniques.

There are two basic situations in which this can occur:
 * If the person in front jumps up a set of stairs while the person in back does not, the person in back will teleport forward. This can be done at any time during the game, as long as the player has a sufficiently long set of stairs.
 * Perform the "Mario Flying Glitch" above, on the fountain one screen east of the "Hoohoo Mountain Watering Hole", and have Mario go straight down. (To do this, have Mario fill up at the fountain, then move north a bit, then have Luigi hit Mario with the hammer four times. Mario should fill up again, but when the player moves, Mario will teleport right next to Luigi, but up on a ledge.) Drop off the ledge onto the stairs below, and if Mario moves too far, Luigi will catch up to him, and they will teleport back a short distance. To end the glitch, enter the screen on the left, or have Luigi High Jump on Mario.

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. The lack of music changes also happens with the Luigi Dunk, and even with the advanced Firebrand and Thunderhand techniques, although it works less frequently.

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.

Thirdly, if the player saves at the "Teehee Valley Fungitown Side" Save Album when Mario is Mini-Mario, or if Luigi has been Luigi-Dunked, no music will play. The music returns, however, when the player leaves that screen.

The player must have advanced Swing Bros. to do this. The player must go to the Fawful battle and knock him out of the mech. Once hes out, the player must use the Swing Bros. to steal his Golden mushroom. Then the player must make Fawful give them a Game Over, but instead of start from last save point, they must start from Beanbean palace. The player will keep the Golden Mushroom, and the player can do that with Fawful as much as he/she likes.

There are many situations where the wrong sound is played or sounds are sustained when they shouldn't be. Here is a list:
 * When Gigi demonstrates the advanced Firebrand technique, and also in Mario's "surprise" to Gigi (when Mario is sitting in the chair), the Thunderhand sound is played instead.
 * If Mario and Luigi run into an Ankoopa while they are using the Firebrand, the firebrand dashing sound is continuously played until the suitcase is opened, or the player leaves the screen or enters battle.
 * If Mario and Luigi run into one of the rolling metal bars while any one of the six hand sound effects are being played ("charging", "fully charged", and "in effect", with two of each), it will be continuously played. Some of the sounds can even be stacked on top of each other (so that they're playing at the same time). As with the above example, the sounds can be stopped by opening the suitcase, leaving the screen, or entering battle.
 * If Luigi gets filled up with water by the garden hose that is northeast of the Teehee Valley entrance, instead of Luigi making his normal sound effect when he empties himself of water, the sound of an Oho Jee speaking will play instead.
 * If Mario and Luigi High Jump or Spin Jump into the flaming rock southwest of Hoohoo Village, they will yell, but if they simply walk or jump normally into it, they will perform the same motions but not make any sound. Also, if Mario is filled with water and walks into it, he yells but Luigi doesn't.


 * When Mario and Luigi exit the Starbeans Cafe, the sprite of the person in the back is actually in front of the sprite in the person in front for a short while.
 * If the player goes to Guffawha Ruins when they have both Mario and Luigi, the gates will be closed, but if the player performs one of the "dual jumps" (High Jump, Spin Jump) under the arches, the player will be on top of the arches.
