Marvel Super Heroes vs. Street Fighter

Alternate Colors for Secret Characters
When selecting a secret character (see codes below), finish the code by pressing Light Kick and Fierce Kick instead of Light Punch and Fierce Punch.

Beat 'em While They're Down
After defeating your opponents, press and hold START. Normally your character wont be able to move after the round is over but by holding START you will not only be able to move freely (until the next round starts) but you will be able to hit your opponent and even do a Super on them!

Change Battle Order
When the screen shows which teams will be battling, press Punch or Kick three times to change the order of battle.

Dan's Explosion
Pick Dan as your fighter then anyone else at the vs. screen hold the light punch until the word fight disappears when the match begins. Dan will fall into a small explosion.

Double Team Spiderman
Start a new game and choose any character for your first choice followed by Spiderman as the second character. Deliberately lose, then continue and choose Silver Spiderman as your first character. The other Spiderman should be selected as your second character.

Extra Hits on Super Combos
While doing a super combo, slide your hand back and forth on the buttons pressing the same strength punch and kick simultaneously. Do this as fast as you can. 95% of the time you'll only get a few more hits but if you do it perfectly you can get a lot more.

Fight Secret Characters - Japanese Version
To fight a secret character in the Japanese version you must do a certain amount of team super finishes.
