Alternately, playing 800 versus mode battles. After you have played 800 battles, the winner of the battle will be challenged by Luigi. Defeat him and he will become a playable character. If you lose, Luigi will challenge the winner of the next versus mode battle.

Mewtwo

Mewtwo will appear at random at the end of a multi-player match and challenge the winner. He will be unlocked as a selectable character after he is defeated.
Alternately, in versus mode, play 700 battles or get a total of 20 hours of game play.

To unlock Mewtwo, play 20 hours in melee vs. mode (combined umber of human players times the number of hours). For example, if you play 1 human player vs. 3 CPU players, play 20 hours; 2 players vs. 2 CPU players, play 10 hours; 3 players vs. 1 CPU player, 7 hours; 4 player vs., 5 hours.
To get Mewtwo easily, go into Custom Rules Melee and change ‘Stock’ to ‘3’ and ‘Item Flow’ to ‘None’, and ‘Stock Time Limit’ to ‘Off’. Choose two of your best characters (for fighting Mewtwo) and go into a match in the Pokemon Stadium level. Place both fighters on the Pokeball in the middle. Do not pause the game. Unplug the controllers, and leave the system on overnight to accumulate game time. Plug in the controllers again, and have one of the fighters die three times. If enough hours have been obtained, Mewtwo will challenge you. Defeat him to unlock him next to Jigglypuff as a playable character.
This trick is useful if you do not have a second controller and want to unlock Mewtwo. Enter the ‘Custom Settings’ screen, and set up a versus game with a ‘Damage Ratio’ of ‘0.5’ and a ‘Stock’ of ’99’. Start a Tiny Melee with a human as player one (preferably being a character you can defeat Mewtwo with) and three other players at a low CPU level of 1. Start the game at Hyrule Temple, then leave it idle overnight. For best results, have the three CPU players be Captain Falcon, Prince Marth, and Pikachu. About eight and a half hours later, the fight should just have ended. Repeat the process every night until you have accumulated twenty hours and can fight Mewtwo. However, the human player should be the winner of the final fight or Mewtwo may not appear. Note: You can see how many versus hours you have accumulated by going to the ‘Misc VS Data’ section.

Set up a one life battle with as many humans as possible and no CPU players. Leave the game on overnight, then defeat the other players a nd Mewtwo.

Alternate music

Hold L or R and select a stage in multi-player mode. Keep the button held until the match begins. Note: Only certain stages have new music.

Hold A and press Start at the title screen. Different music will play at the main menu.

Hold L + R + Z + A + X + Y at the title screen. The music on the menu should change. Sometimes it will require multiple tries.

Use the following trick to listen to any desired music in the gallery of trophies. After unlocking the Sound Test, use it to find a song you like, then press A to play it. Then, press B to exit. When you go to the trophy gallery, that song will be playing instead of the usual one.

By selecting a stage with A or holding L or R and pressing A, the stage will have different music.

Call Team Star Fox

Want to surprise your friends with an unexpected move? Fox McCloud has a cool easter egg maneuver that can only be pulled off on the Great Fox and Venom stages. Find yourself a safe spot where you won’t immediately be attacked by an opponent, then rapidly press left, right, left, right on the digital pad. If you did it correctly, Fox will kneel down and call up his friends. Falco, Peppy and Slippy will respond (their faces will appear at the bottom of the screen) and either give you useless advice or tell you to get out of the way as they’re about to attack your opponent. Not a very useful move, but a cool thing to amaze your friends with nevertheless. Note that you can only perform this maneuver once every battle.

Earn More Coins

Did you know that the amount of coins you receive after a match is directly related to how often you ‘smash’ the stick during battle? If you want to make easy money, enter the Adventure Mode and make your way all the way through the first level. But before you exit, stand on a secure platform and wiggle the control stick right and left ‘Decathlon’ style. You don’t even need to complete smash moves — moving the stick all the way is enough to earn cash. When you exit and finish the stage you will receive a much higher number of coins. You can do this in any mode or on any level, but you get a lower amount of coins in Vs. Mode (unless all players do this trick at the same time).

Fun With Trophies

While going to the Collection screen to view your trophies, hold L and the trophies will be displayed in rows. Hold R and the trophies will be arranged in a circle. Hold Y and the trophies will be arranged in a triangle.
If you have Sound Test unlocked, note that the last music you listened to will also play while you view your trophies.

Peach’s Quick Float

In Super Smash Bros. Melee, Princess Peach is the ultimate throwback to Super Mario Bros. 2. Everything from plucking radishes from the ground to using her dress to float for long distances. Her dress is without a doubt one of her most useful tools. Knowing that Peach fanatics want to use it liberally, the developers of the game, HAL, have added in a quick float feature. Instead of having to jump full height to activate the float, you can press Down + X/Y at any time to start floating. Hold the button down to continue hovering. Use it while standing, and you can even hover inches above the ground if you like! A graceful girl indeed.

Pick Your Pose

You can select the pose your character strikes when you win a battle. Simply press B, X, or Y when the match ends. Each button corresponds to a specific winning pose.

Random Character Select

Super Smash Bros. Melee has a built-in random character select feature. Simply place your coin in one of the empty spaces on the selection screen (in the corner next to Pichu or on the opposite site). The game will automatically place your token on a random character.

Random Character Tournaments

Want to set up a more interesting tournament with your friends? When you’re at the character/name setup screen in Tournament Melee mode, press the L and R buttons at the same time to change your character icon to Ditto (the shapeshifter of Pokemon fame). This will set that player’s character selection to random. Note that this will only work in the Winner Out/Loser Out modes — not the standard Tournament setting.

Start Battle as Sheik

Want to start a battle as Sheik, not as Zelda? Keep on holding down the A button when you pick Zelda on the character select screen. When the battle begins, you will hear the ‘unlock chime’ from Legend of Zelda and you will start out as Sheik.

Super Shield

Sure, you know that hitting L or R brings up a protective shield — but how about making it last longer? When blocking, hit L or R lightly (not all the way). This will create a much larger Super Shield that shrinks at a much slower rate than the standard shield. The downside is that it’s not as strong. If you want a more powerful shield, press L/R all the way.

Unlocking Hidden Characters

Naturally Super Smash Bros. Melee is filled with playable characters. There are 14 selectable as soon as you boot it up, but you’ll find another 11 waiting for you to be unlocked for a total cast lineup of 25 characters. There are genuinely new characters as well as clones. Clones usually share the same moves and attacks as one of the main characters with some subtle adjustments. Apparently there are several ways of unlocking characters either via Vs. matches or single-player mode. Once the conditions are met, the secret character will appear and challenge you to a battle. Win the battle, and you get the character. Here’s the ways to do it:

Jigglypuff — Clear Adventure or Classic mode with any character or play Vs. more than 50 times.
Luigi — Luigi’s appearance depends entirely on your level time for the first Adventure mode level. The time stops the moment you jump the ‘flag’ finish line at the end of the Mushroom Kingdom sidescrolling level. Look at your seconds counter and try to time it so that you get a ‘2’ (as in Luigi, the #2 Mario Brother) in your seconds (like 22, 52, 24, etc). If you got it right, you will see Luigi appear over Princess Peach’s Castle in Adventure mode during a cut-scene. Complete the Adventure and he will appear after the credits. Or: Play Vs. Mode more than 800 times.
Young Link (Clone of Link) — Clear Classic or Adventure mode with 10 characters (two of which have to be Link and Zelda/Sheik) or complete 500 Vs. matches.
Dr. Mario (Clone of Mario) — Clear Classic or Adventure mode with Mario without using continues (Tip: use Very Easy difficulty) or play more than 100 Vs. matches.
Ganondorf (Clone of Captain Falcon) — Clear Event Match 29 or play more than 600 Vs. matches.
Pichu — Clear 200 Vs. Matches, clear Event Match 37, or conquer Classic mode with Mewtwo.
Marth — Use the original 14 characters at least once in Vs. or another regular mode, or play more than 400 Vs. matches.
Roy (Clone of Marth) — Clear Classic Mode with Marth without using a continue or play more than 900 Vs. matches.
Falco (Clone of Fox) — Clear 300 Vs. Matches or beat the 100-Man Melee.
Mewtwo — Rack up 20:00 hours in Combined Vs. Play Time or play 700 Vs. matches.
Mr. Game & Watch — Clear Target Test, Classic, or Adventure mode with all 24 characters. Or: play more than 1,000 Vs. matches.

Unlocking Hidden Modes

There are several hidden modes of play hidden within the single-player mode as well as the options menu. Event Matches are a huge part of single-player and at first sight it appears there are only 30. However, as you unlock new characters and stages new Event challenges will be revealed.
Event Matches 31-39 — You’ll need to unlock Jigglypuff, Luigi, Dr. Mario, Falcon, and Young link on top of clearing the first 30 Event Matches.
Event Matches 40-50 — Unlock all hidden characters and stages.
As a special treat there is an extra Event Match that allows you to unlock the special Sound Test feature in the options menu.

Event Match 51 — Clear all previous events.
Sound Test — Unlock every stage and character.
For die-hard players, there is also a hidden Score Display option:

Score Display — Get a total of 5000 KOs and you will unlock this option that lets you see the players’ scores during a match (instead of afterwards).
Finally there is a secret All-Star mode which sends you fighting all 25 characters in a gauntlet-type setup. You will have access to three heart recovery items, but no more so you’ll have to ration your energy properly.

All-Star mode — Unlock all 25 secret characters.
It should be noted that there are numerous hidden trophies that unlock randomly with your progress, so be sure to keep your Vs. Match count high and complete as much as possible if you’re looking for more trophies.

Unlocking Stages

SSB Melee has a lot of stages to select from. While the select screen only indicates you can unlock five there are actually more than that. Note that there is a certain random element to the unlocking of the first four stages. Sometimes, the first stage you unlock isn’t Brinstar. If it didn’t unlock at 50 matches, it will unlock at 100, 150, or 200.
Planet Zebes: Brinstar Depths (Metroid) — Play 50 Vs. matches.
Eagleland: Fourside (Earthbound) — Play 100 Vs. matches.
F-Zero Grand Prix: Big Blue (F-Zero) — Play 150 Vs. matches.
Kanto Skies: Poké Floats (Pokémon) — Play 200 Vs. matches.
Mushroom Kingdom II (Super Mario Bros. 2) — Get Birdo or Pidgit trophy from Super Mario Bros. 2.
Superflat World: Flat Zone (Game & Watch) — Unlock Mr. Game & Watch and defeat Classic mode with him.
Battlefield — Defeat All-Star Mode (secret mode) with any character.
Final Destination — Clear all 51 Event Matches.
Dream Land (Classic N64 Kirby Stage) — Complete Target Test successfully with all 25 characters.
Yoshi’s Island (Classic N64 Yoshi Stage) — Hit 1,323 feet (or more) in the Homerun Contest with Yoshi.
Kongo Jungle (Classic N64 DK Stage) — Finish 15-minute Melee with any character (Tip: use Donkey Kong with his down+B ground slap).
Random Stage Switch — Unlock all secret stages (except for the classic N64 stages and Battlefield and Final Destination) to reveal a random stage switch. As soon as you start your melee from the character select screen the match will start. This means you don’t have to waste time loading the stage select menu.

Easy Back From Select

Want to get back to the previous menu from the character select screen, but don’t want to waste time going up and clicking on ‘back?’ Here’s a little shortcut: simply hold down the B button and the cancel command will be triggered after a second or so.
