Alternate Japanese systems
To see several Japanese versions of the Nintendo systems in the trophy room, as well as a bonus Virtual Boy, switch the language on the game to Japanese.

Alternate Multiplayer Music:
After unlocking the Sound Test (portions of this trick can be done before unlocking the Sound Test, however), you can change the music that plays on some of the stages. When selecting them, hold L or R until the stage loads. Each human player competing in the match must also hold L or R. The stage's music will change. This trick works on the following stages:
- Infinite Glacier: Icicle Mountain (Retro theme from Balloon Fight for NES)
- Termina: Great Bay (The theme of Lost Woods from Legend of Zelda: Ocarina of Time for N64)
- Hyrule: Temple (A remix of various themes from Fire Emblem titles)
- Yoshi's Island: Yoshi's Island (Stage 1-1 and world 1 map remix from Super Mario Bros. 3 for NES)
- Kanto: Pokémon Stadium (The Trainer Battle theme from Pokémon Gold & Silver for GBC)
- F-Zero Grand Prix: Big Blue (A theme from Mach Rider for NES)
- Eagle Land: Onett (The theme of EarthBound)
- Mushroom Kingdom OR Mushroom Kingdom II (The Fever theme from Dr. Mario)
- Special Stages: Battlefield (The theme used in Multi-Man Melee fights)
- Special Stages: Final Destination (The theme used in Event 51, The Showdown)

Sometimes, the music will change automatically (12% chance).

Always Get Desired Pokemon:
Go to training mode and continuously select 'pokeball' from the menu. Whilst throwing them, look out for your favourite pokemon to appear, and STOP on that one. After it has done its move, go to 1-p adventure or classic mode, and the first pokeball you open will be the one preveously found on training. After this, the rest of the pokeballs you open are random. A good trick to use in this way is to do it with mew, because you get bonus points for seeing her.

You'll have to fight Luigi; defeat him and you can play as him.

Character Unlock: Marth:
To unlock Marth from the Fire Emblem series, complete Classic mode with all 14 regular characters (not ones you've unlocked). Marth will then challenge you; beat him to gain him as a selectable character.

Mode Unlock: Random Stage:
Unlock every stage except for Battlefield, Final Destination, Dream Land N64, Yoshi's Island N64, and Kongo Jungle N64. This option appears in Additional Rules under Custom Rules in VS mode and allows you to exclude stages you don't want to go to when you use the Random stage select option.

New Background Music for Gallery Mode:
Once you have unlocked the Music Test, choose a song you would like to hear in the Gallery mode by pressing A. Now exit by pressing B, and then go to Gallery mode. Now you can look at trophies while listening to your favourite SSB: Melee song;)

Random Character Select:
The vacant spots in each bottom corner of the character select screen (left of Pichu and right of Roy) will randomly select a character for you if you place your token there and press ''A.''

Random Character Select (Tournament Melee):
When playing Tournament Melee, press L and R simutaneously at the character select screen and your character box will become the Pokémon, Ditto. This purple blob represents ''Random.'' However, this trick only works in ''Winner Out'' and ''Loser Out'' matches.

Samus's Secret Throw:
Samus has a secret throw that can be performed at any time. Its a bit more difficult to perform than Fox and Falco's secret taunts. Press Z repeatadily to extend her grappling hook but not so repeatadily as to shield. While pressing Z, rotate counter clockwise on the Control Pad. If done properly, her grappling hook will extend by three times. It will now remain this way until he is KOd (then you must redo the trick). The longer grappling hook is very useful. It won't grab opponents unless you press A or Z once it touches them. It will also home onto the nearest opponent if you hold L once firing it out. The grappling hook is also longer in the air which proves to be a much more useful recovery move than her Screw Attack (Up + B).

Stage Unlock: Battlefield Stage:
To unlock the Battlefield stage, complete the All-Star 1-P mode for the first time.

Stage Unlock: Big Blue Stage:
To unlock the Big Blue stage, you must play at least 150 matches in VS. mode (without quitting).

To unlock the Fourside stage, you must play at least 100 matches in VS. mode (without quitting).

Stage Unlock: Kongo Jungle Stage:
To unlock the Kongo Jungle from the N64 version of this game, complete the 15-Minute Melee. I'd recommend using Donkey Kong and constantly use his Down + B move the entire time (thanks to DEngel's Secrets guide, for I used that strategy to unlock this myself)!

Stage Unlock: Mushroom Kingdom II Stage:
To unlock the Mushroom Kingdom II stage, which is from Super Mario Bros. 2 on the NES, simply collect a Birdo trophy. The trophy is random, but when you find/win it, you get this stage.

Stage Unlock: Poké Floats Stage:
To unlock the Poké Floats stage, you must play at least 200 matches in VS. mode (without quitting).

Stage Unlock: Yoshi's Island Past Stage:
To unlock the original Yoshi's Island stage from the N64 version of the game, use Yoshi and hit over 1,350 ft. (400m in the JP version) in the Home-Run Contest. To do such, stand next to the Sandbag and TAP the X or Y buttons to jump, then use the Down + A move to hit the bag for around 30% damage each time. Do that about 4 times to get the bag up to around 100-110% damage. Since you won't have much time left, get the bat and use a Smash hit to send the bag flying. If you did it all well enough, you should make it well over the required distance.

Transform with Zelda before battle:
In Classic Mode, if you pick Zelda, you can transform into Sheik (or vice versa if you're already playing as Sheik) before the battle starts. On the match-up screen, hold Down (Control Stick) + A until the battle starts. You'll automatically transform before it begins.
