These are beta elements from Super Smash Bros. Melee

Beta elements
Through the use of an Action Replay, many unused/unfinished stages can be found. The first is a large, gray stage with the background appearing to be some kind of pub. 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 three other stages, "AKANEIA" (a possible predecessor to Castle Siege from Super Smash Bros. Brawl, a home world for Fire Emblem) "10-2", and "Dummy", which all crash the game when loaded. The last stage, named IceTop (a possible precursor to the Summit stage from the sequel, which belongs to the Ice Climbers) which simply loads Icicle Mountain except without music. In addition to these stages, the entire Debug Menu, which was used in pre-release testing, can be used, 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 the text in the Proximity Mine trophy was only tampered with a minor amount (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, 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. King Dedede was also supposed to be playable but was cut because of the same reasons he was cut in SMB64.

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 Poké Ball Pokémon but was removed for unknown reasons, however it still appears in tournament mode as a place holder.

Lucas was originally meant to replace Ness. However, due to a delay of MOTHER 3 in Japan, Ness was kept in.

Marth and Roy were originally going to be only in the Japanese version, however they were kept in the final version. Because of this, they do not talk in English, rather they speak in Japanese. An early box art was made, C. Falcon's red color change's back was going to say Hell Hawk, and All - Star Playable Character Introductions were scrapped.

In addition to existing bonuses, there are seven hidden ones that are only accessed by the cheating device. They are not required for obtaining the Diskun trophy.
