Editing New Super Mario Bros.

*''[[Mario Bros. (game)|Mario Bros.]]'' - The respawn jingle from this game plays in the [[#Mario Vs. Luigi|Mario Vs. Luigi]] mode when Mario respawns from defeat. [[World 2-2 (New Super Mario Bros.)|World 2-2]] and [[World 8-6 (New Super Mario Bros.)|World 8-6]] contain [[floor (Mario Bros.)|floor]]s that Mario and Luigi can hit from below to knock over enemies walking on top of them, similarly to one of the main gameplay mechanics of ''Mario Bros.''

*''[[Super Mario Bros.]]'' - There are two unlockable skins for the bottom screen that resemble something of this game; one shows a close-up of 8-bit Mario and Luigi sprites, and the other one is a secret unlockable skin and it features [[Mario]], [[Luigi]], and some [[Goomba]]s in [[World 1-1 (Super Mario Bros.)|World 1-1]]. The overworld Multiplayer stage is also based on World 1-1. In the end of [[World 1-2 (New Super Mario Bros.)|World 1-2]], there is a hidden path over the ceiling before the final [[Warp Pipe|pipe]] that leads to a secret pipe, which is a direct reference the same secret in [[World 1-2 (Super Mario Bros.)|the same level]] of ''Super Mario Bros.'' [[Bowser]] and [[Dry Bowser]] are defeated the exact same way as in the castles in this game - by hitting the [[axe]]/[[skull switch]] which makes the bridge he is standing on fall into the lava or a bottomless pit, respectively. The latter also applies to the final battle against Bowser and Bowser Jr. The color scheme of the [[Mega Mushroom]] in ''New Super Mario Bros.'' is the same as that of the [[Super Mushroom]] in this game. If Mario finishes a level with the last two numbers of the time limit being the same, the "level complete" theme from this game plays in place of the normal one. A cover of this game's death theme plays when Mario loses a life. The first four levels' settings of the game are very similar to those of this game: the first level takes place in a grassy field, the second takes place underground, the third takes place up high on trees/giant mushrooms, and the fourth is a tower/castle level with a boss waiting for Mario at the end. The music in the [[Toad House]]s is a cover of this game's ground theme. Also, if the player presses {{button|ds|L}}, {{button|ds|R}}, {{button|ds|L}}, {{button|ds|R}}, {{button|ds|X}}, {{button|ds|X}}, {{button|ds|Y}}, {{button|ds|Y}} while in the pause menu on the map, then Mario can no longer backtrack in levels, like in this game. In the minigame [[Danger, Bob-omb! Danger!]], the background music is an arrangement of the castle theme from this game. The sound effect for when Mario or Luigi slides down the [[Goal Pole|pole]] is reused, albeit reversed. Other sound effects are reused including the coin, stomp, bump, fireball, jump and warp pipe/power down sounds.

*''[[Super Mario World]]'' - The [[item storage|Item Stock]] returns from this game. A Monty Mole, which first appears in this game, appears as part of a boss called Monty Tank. Wigglers also appear in the game. [[Grinder]]s don't appear in ''New Super Mario Bros.'', but spiked balls appear in the game, having the same function. Also, this game features [[Pipe Cannon|Warp Pipe]]s that can shoot the player into the air like [[Cannon]]s. The jump sound effect is reused when Mario or Luigi jumps.

*[[Mario Kart (series)|''Mario Kart'' series]] - The [[Lightning]] item was once considered for Mario Vs. Luigi, retaining its ability to shrink the opponent player.<ref>{{cite|date=May 24, 2005|title=Mario Comes Full Circle In New Super Mario Bros.|url=https://www.pressthebuttons.com/2005/05/inew_super_mari.html|publisher=Press The Buttons|accessdate=April 9, 2024}}</ref>
