Starting the game with a Pikmin save file on their memory card grants the player the Captain Olimar trophy. This is the only legitimate way to obtain this particular trophy.

By selecting Ganondorf's classic trophy and then changing to the "nighttime" background, the trophy's eyes change to yellow.

Zooming into Ness's shorts on his trophy shows that he wears very plain white briefs.

Jigglypuff is the only character whose voice actor changes depending on the game's language setting. When changed to Japanese, French, or German, her voice actor will change as well as the name. In Japanese, it becomes Purin, in French, it becomes RONDOUDOU, and in German it becomes Pummeluff. A new voice actor is used when announcing her name as RONDOUDOU and Pummeluff and is the only time a different announcer is used in any Melee version.

There are actually multiple differences between the NTSC and PAL versions of the game. Besides some minor changes, there was a huge change to a lot of character moves, making them weaker or more powerful. The language setting in the PAL version can be switched between English, French, German, Spanish and Italian, with the French and German settings having new voice overs for character name changes during character selection.

Roy did not star in a game before Melee. Although Fire Emblem: Fūin no Tsurugi (Fire Emblem: Binding Blade) is where Roy had his starring role, the game came out March 29th 2002, while Melee was released November 21st 2001 in Japan. Roy was put into Melee to promote Fūin no Tsurugi's release in Japan, and was originally intended to be an exclusive character to the Japanese region.

Mario's vocals for his down special move and back throw were used in Mario vs. Donkey Kong. This is the only time a vocal from any character in a Super Smash Bros. game was reused in a game outside the series.

A Male Wire Frame's name will be displayed on Pokemon Stadium as 'ZAKO otoko'.

Changing the language to Japanese on an English version of the game results in the Ice Climbers being called simply "Ice Climber" as Japanese does not differentiate between singular and plural written words in the way English does.

Luigi is the only character from the original Super Smash Bros. to not appear in Melee's intro.

Donkey Kong has a hitbox attached to his necktie. This is likely included to prevent projectiles from missing due to slipping between his arms and ending in the empty space of his standing animation but it also artificially inflates his overall hitbox in may other animations.

Falco's voice actors, Ben Cullum and Hisao Egawa, are credited in the credits even if he has not been unlocked yet. This is likely due to his appearance in the intermission of the Corneria stage in Adventure Mode.

Link and his clone, Young Link, both use the same model for the Hookshot. This makes Young Link's look rather large compared to Link's.

If the game language is switched to Japanese, Mewtwo will speak in full sentences for some of its victory poses. In English, Mewtwo only laughs during its victory poses and taunt.

Because of Super Smash Bros. Melee's status as a launch title, it was specifically designed to showcase new features that the N64 wasn't capable of. This is why the game's opening sequence is a high-quality, full-motion video, which the N64 was incapable of producing. The developers at HAL even worked with 3 other production companies in Tokyo, Japan, to make Melee's opening sequence as outstanding as possible.

Melee was in development for 13 month's, and the game's director, Masahiro Sakurai, had no holidays and cut short his weekends to work on the game. He even went far enough to say that his lifestyle while developing Melee was "destructive", due to how he felt pressured to deliver a greatly improved game. In the end, Sakurai and his team's efforts paid off. Even after the release of Super Smash Bros. Brawl's release, Sakurai still dubs Melee to be the sharpest game in the series.

In Event 39: Jigglypuff Live, the screen in the background will sometimes focus on your Jigglypuff. If you use "Sing" at this very moment, the other 3 Jigglypuffs will fall asleep, and for longer than usual. This Easter egg only appears in Event 39, which may be appropriately placed in sync with Jigglypuff's National Pokedex number, 39.

The developers initially considered replacing the character Ness with Lucas (the protagonist of the Japan-only GBA title Mother 3), and planned on making Marth and Roy Japanese-exclusive fighters. However, Ness remained the spokes-fighter for the Earthbound trilogy due to consideration for delays in releasing Mother 3, and Marth and Roy were made available worldwide due to fans' desires to play as the Fire Emblem duo.

One of the battle bonuses you can get is called 'Switzerland,' and is worth 12,00 points. You obtain it by not attacking (including missing) and not being attacked. This is a reference to Switzerland's neutrality during both World Wars.

There are six "unused" entries in the debug menu's level select for Versus matches. While most of them crash the game, only two of them work properly. The first one, TEST, is a large terrain test stage with a unique backdrop. The background comes from a coffee shop in Palo Atlo, California. The second one, TSEAK, is a test stage for "Break the Targets" and was reserved for Sheik.

In the background of the trophy room, several Nintendo consoles can be seen. The room includes a Nintendo 64 with the original Smash inside, a Nintendo Power with Super Smash Bros. on the cover, and NES, a SNES, and several other objects. If you change the language settings to Japanese, you will find that the NES and SNES change to a Famicom and Super Famicom, and next to the sunflower a Virtual Boy is added.

The Helirin is incorrectly named the Heririn. This was fixed in the PAL version.

The Banzai Bill trophy states that the Banzai Bill came from Super Mario Bros. 3, when it actually came from Super Mario World.

The Metroid trophies claim that the original Metroid was released in 1989 (8/89), but it was released in 1986.

The Great Fox trophy says that it first appeared in Star Fox, but its debut was actually in Star Fox 64.

The original boxart did not feature Link or Pikachu, and instead featured Mario being attacked by Bowser's Fire Breath move.

On the description of the Meta Knight trophy, it states that he made his debut in Kirby Super Star. This however is incorrect, as his first appearance was in Kirby's Adventure, 4 games before Kirby Super Star was released.

In a beta version of the Great Bay, the laboratory was an actual part of the stage, and players could walk inside. In the final version, the laboratory is now a part of the background.

The Pokemon, Ditto, was meant to be a possible helper when a Pokeball was thrown. He was supposed to transform into the player that threw the ball and would help fight. However, there were problems with its programming and it was removed. By using an action replay, Ditto can be put back into the game, but he is lacking his "transform" ability. Instead, all it does is say "Meta!" (it's Japanese name being Metamon) and disappears. Anyone who runs into it is dealt 7-8% damage.

Captain Falcons' red costume was originally planned to say "Hell Hawk" on the back.

The Metroid trophy has an image reflecting off of its shell. The image is of the space station from the beginning of Super Metroid.

Luigi's voice is just an altered-pitched version of Mario's voice.

In Captain Falcon's "break the target" room, a picture of dolphins can be found on the left-most wall. This may be a reference to the original codename of the Gamecube, which was "The Dolphin".

In Luigi's "Break the Targets" room, the small square you stand on is actually a Nintendo Gamecube.

On the Metal Mario trophy, if you look closely you can see the 'Yoshi's Island' stage reflecting off of him.

You can play as Master Hand without hacking. You can only play as him in controller port 3 and his moves are activated through the D-pad rather than the joystick.

An Excitebike racer from the game Excitebike, Balloon Fighter from the game Balloon Fight, Urban Champion from Urban Champion and Bubbles from Clu Clu Land were considered as characters that could be used to represent the NES era of Nintendo in the game, but Sakurai decided that Ice Climbers would be far more fitting as fighters.

The trophy for the "Motion-Sensor Bomb" shows that it came from "TOP SECRET". This was actually supposed to say "Perfect Dark 5/00", but due to Microsoft's acquisition of Rare, creators of Perfect Dark, they had to change it.

The Letters "2L84ME" (too late for me) are printed on the back of the Barrel Cannon Trophy.

If you go into the Debug Mode of the game using Action Replay, you can find intro screens for characters that were going to be used for All-Star mode while it loaded. This was most likely scrapped, due to the addition of fighting more than one character during All-Star Mode

There are many Regional differences between the Japanese and U.S. versions of Super Smash Bros. Melee. They include name changes (Jigglypuff is named Purin and Bowser is named Koopa in the Japanese version), event names (Time for a Check Up is Don't Hog The Spotlight, Bro in Japan), and different names for items (Bob-Omb is Bomb Soilder in Japan).

The main character of the game Devil World, Tamagon, appeared as a trophy in the Japanese version of Super Smash Bros. Melee. Tamagon was removed in the American version of the game but the trophy can still be found with Action Replay, complete with a translated description. Stranger still, the Tamagon trophy was removed outright from the European version of the game and cannot even be found with a cheat device, despite the fact that Devil World was released in European countries.

In early versions of the game, the Princess Daisy trophy contains a third eye beneath her hair if viewed at the right angle.

Hideo Kojima had requested Metal Gear Solid's Solid Snake be in the game, but due to time constraints he couldn't be added to the game's roster. Sonic the Hedgehog also nearly made it into the game. Sonic's creator Yuji Naka stated that Sonic was going to be in Melee, but the plan fell short due to time constraints.
