List of Super Mario Advance 4: Super Mario Bros. 3 glitches

This is a list of glitches found exclusively in the game Super Mario Advance 4, a remake of Super Mario Bros. 3. For glitches found in the original Super Mario Bros. 3 or the version included in Super Mario All-Stars, and possibly Super Mario Advance 4: Super Mario Bros. 3 as well, see List of Super Mario Bros. 3 glitches.

To do this glitch, Mario or Luigi must have completed. It will have a "completed" white icon, however, if Mario goes to the left, so that the level is off-screen and back, the icon will turn yellow.

To do this glitch, the player must hold and  at the same time, and Mario/Luigi will run backward.

This only works in Super Mario Advance 4. If a Starman runs out in this version, Mario will have a slightly washed-out color palette. This will be fixed if he takes a warp pipe or door, takes damage, beats a level, or gets a power-up (other than a Starman).

If the player goes to World 3-3 or 3-8 and lets Boss Bass jump out of the water after Mario or Luigi, the player must repeatedly press while Boss Bass dives into the water and until his head pops up they must stop. If done correctly, Boss Bass doesn't hurt the plumbers but are still stuck inside and the player cannot escape except by exiting the level or restarting the game.

Fast Underground Music
If the player is on the map and uses a Starman and goes to a pipe, after the Starman is done, the underground music will play very fast.
