Beta Elements
Through an Action Replay, a large, gray stage with the background appearing to be some kind of pub, is accessible. The music is the same as used on Fox and Falco's stage Corneria. This is assumed to be a test stage because of its name, which on the debug menu is TEST. There are also four stages, named AKANEIA (a possible predecessor to Castle Siege from Super Smash Bros. Brawl, a homeworld for Fire Emblem), 10-2, IceTop (a possible precursor to the Summit stage from the sequel, which belongs to the Ice Climbers), and Dummy, a test stage that freezes the game when opened. In addition to this, the entire Debug Menu, which was used in pre-release testing, can be used when the game is hacked, allowing for complete editing of anything in the game. Giga Bowser, both male and female Fighting Wire Frames, Master Hand, Crazy Hand, and even Sandbag are all playable (to a limited extent) via the Debug Menu.

The Japanese version actually had an entirely different Motion-Sensor Bomb; it is actually a Proximity Mine from Perfect Dark rather than the Motion-Sensor Bomb from "TOP SECRET" (actually GoldenEye 007) that appeared in the international version. The Proximity Mine's trophy can be viewed in English due to the language option, and this screenshot shows that (in an almost cheap manner) the text in the Proximity Mine trophy was only tampered minorly (with only a few removals of references to Perfect Dark) for the final Motion-Sensor Bomb trophy. Why the Perfect Dark Proximity Mine was changed to a GoldenEye 007 Motion-Sensor Bomb remains unknown to this day and is rather ridiculous, especially considering that the games from which the items originated were even made by the same company, although the fact that Nintendo hides the Motion-Sensor Bomb's trophy's debuting game entry with the words "TOP SECRET" in the international versions suggest that the item change may very well have had to do with censorship (however light). Another important graphic change was the Topi enemies in the Ice Climber stage - in the Japanese version, they were seals, but this changed to yeti creatures in the international versions due to animal cruelty protests. The "Temple" stage originally had an elevator that led to the bottom of the stage, and had a fixed appearance. Players could also walk through the laboratory in Great Bay. Hyrule Temple had two mysterious platforms in the center of the stage. These platforms can also be seen in the game's Special Movie. The stages Yoshi's Story and Mushroom Kingdom I had different designs altogether. Onett's music also sounded different. In one of the character select screens, Zelda seemed to be unlockable, as there is a question mark where her picture would be.

It can also be seen that, through Melee's Debug menu, it is possible to have a match with six characters instead of four. Also, Ditto was shown to appear as a Pokeball Pokemon but was pulled for unknown reasons.
