Editing List of Super Mario Advance 4: Super Mario Bros. 3 pre-release and unused content

[[File:SMA4 E3 Logo.jpg|thumb|The original logo for the game.]]

In the trailer at E3 2003, the logo looked slightly different to the one seen in the final game. The footage showed that the background had horizontal parallax scrolling, but this was removed in most levels except for underground and airships. The layers still scroll vertically though. The way [[Advance Coin]]s were indicated in the status bar changed between this build and the final release versions. Also, like previous versions of ''Super Mario Bros. 3'', the trill sound when [[Small Mario|Small]], [[Super Mario (form)|Super]], [[Fire Mario|Fire]] or [[Hammer Mario]] runs at full speed is the same as that of Raccoon and Tanooki Mario. In the final version this was replaced with a lower trill sound while [[Raccoon Mario|Raccoon]] and [[Tanooki Mario]] still have the original trill sound. Additionally, there were no voice samples in the trailer.

Gray switches of varying sizes were found in the game's graphics as an [[e-Reader]] object. It was taken out for unknown reasons. There are also pressed versions of the switches that are unused. Many unused enemy graphics were also found in the game's code. The include:

*[[Flutter]] (''[[Yoshi's Island: Super Mario Advance 3|SMA3]]'') (Unused) This Enemy is fully scripted and acts like the ''Super Mario Advance 2'' [[Wiggler]]s.<ref>[https://www.youtube.com/watch?v=rJvZnRP5HTk YouTube - SMA4, UpaLuppa's (Continued) Demo of early / Unused Stuff on ROM! - Flutter from SMW2:YI]</ref>

*Unused [[Big Boo]] graphics from ''[[Super Mario World 2: Yoshi's Island]]'' (note that these are not the actual Boo graphics used in ''Super Mario World 2: Yoshi's Island'', but ones that were previously unused in it).

The [[Parabomb|Para-bomb]] (based off of its ''[[Super Mario World|SMW]]'' appearance with the ''SMA4'' Bob-ombs), and the [[Porcupuffer|Porcu-Puffer]] are in the game. Both are fully functional.<ref>[https://www.youtube.com/watch?v=cDGsAjHrjbk SMA4 - Forest of Fear!]</ref>

|The arrow wheel, and two early enemies.

Also found in the game was an [[arrow wheel]]. The arrow wheel was slightly different to the ones found in ''Yoshi's Island''. Updated sprites of the gold [[Cheep Cheep|Cheep-Cheep]] and green [[Para-Beetle]] were found too. Both enemies were supposed to appear in ''Super Mario Bros. 3'' but never appeared.

*The Nintendo Presents logo from the beginning of the game. This is actually used in the final game—however, it is using a compressed one.

None of these graphics within the game's code are found anywhere near each other in ''Super Mario World''. They are right next to each other in ''Super Mario Advance 4''; it is unknown whether these were intended to be used, or random data that was mistakenly compiled into the game. Using Lunar Magic, a popular hacking tool for ''Super Mario World'', and YYCHR, a graphics hacking tool for various game ROMs, can prove the fact that these graphics are not anywhere near each other, with the exception of the Koopa and Goomba graphics. Extracting all of ''Super Mario World''{{'}}s graphics from the ROM splits the graphics into different files with a .bin extension, labeled from GFX00 to GFX33 (the numbers are labeled in hex, e.g. GFX 0E). When opened with YYCHR, the "Nintendo Presents" gfx are located in GFX00, the Koopa Troopa's and Goomba's walking animations are located in GFX01. The Koopa Clown Car sprite tiles are located in GFX21, and the font for the status bar is located in GFX28.
