Change team order:
The order of your fighters will appear before a versus match, with "1", "2", or "3". You can select the first and second fighters of your team, and thus change the entire team order. To select the first fighter, press LP + LK for the character marked "1", MP + MK for the character marked ''2'', or HP + HK for the character marked ''3''. Then, press the same button combos to select the second fighter. Press Start to continue.

Switch characters during match:
Use the following to switch between characters in the middle of the game. For example if you choose Cable, Ryu, then Ken, but later in the second stage you want Ryu to appear first -- Hold L for the second character and R for the third character at the versus screen.

Change costume colors:
After unlocking the alternate costume colors, press L and/or R when choosing a character. Information in this section was contributed by Rashad BlackScott.

To get free alternate costumes, select the character with Y instead of A. This is usually makes them brownish, and looks especially good with Blackheart. Information in this section was contributed by Tamscojohn.

Multiple character selection:
Unlock every costume and character to chose multiple people. For example, player one could chose three Charlie's and the other player could also chose three Charlie's.

Bonus characters:
To unlock the characters on the left and right side of the screen in the "?" boxes, you must defeat Abyss in score attack mode.

Evil Sakura and Zhangfei:
Press Down, Down/Left, Left, Back, LK. They will have the same moves plus extra. For example, if you do Sakura's first special, instead of her doing her combo she will do a special beam like Ryu.

Cheaper hidden fighters:
Exit and enter the shop screen until the price of the hidden fighters are lower.

Defeating Abyss:
Select Cable. For Abyss' first form, just block his attacks and then press Y to shoot. Repeat this until he dies. For his second form, distance yourself far as possible and shoot. Repeat until he dies. For his third form, just use Cables Hyper Viper. It takes off 90-95% of his life in one blast and will be a 115-130 hit combo. Then, just hit him once or twice with any attack to defeat him.

To defeat Abyss in his second form, choose Cable. Keep shooting Abyss with the pistol and keep shooting till you have level 1 on the gauge. Execute Cable's Hyper Viper Combo. This should kill him -- if not keep repeating this pattern. The works if you are fast enough to kill him while he performs his short range attacks.

Choose Megaman, Cable, and Cyclops. Play under the easy or medium difficulty setting. At Abyss, use Megaman then jump behind him and shoot. During his second form, use Megaman and continue shooting at him. You should have a level three power bar by now. At Abyss' third form, wait. He always dives down before attacking. When he reappears, do a Triple Hyper combo. If the game is set on very easy and high damage, Abyss should die in one hit.

Abyss' first stage:
Defeat Abyss with any time limit in arcade and score attack modes. His first stage will be unlocked in training and versus modes.

Change clock in background:
To change the time of the clock in the background of the clock level, simply change the system time.
