Pause the game in any level, then hold Jump (default L) and press U D D D (default keys W S S S) to have Guile's Theme replace the background music until you put the code in again.

To play as Mega Man without his Helmet, hold shoot on Ryu on the stage select screen and then press Right Right Right Left. If entered correctly, a sound will play and Mega Man will lose his helmet on the stage select screen.

At the title screen.

Go into password menu, then enter this code. You will start a new game with 4 E-tanks.

At the title screen, select Password, then enter this:

Complete the game with 4 or more Perfects. After the final battle, Akuma will challenge you.

To fight Sagat, you must obtain 4 perfects in the boss rush before Bison. Sagat will show up before the fight with Bison.

Just before killing your stage boss, use your E-tank to refill your health back to maximum. Doing this will trick the game into thinking you've earned a perfect in the round. Once you kill your boss when your health is full, you will earn a Perfect.

If you need more E tanks to beat the game. Just let the timer after you die hit 0, go back into the game and you will have all the tanks you previously collected and you can recollect the E tanks from the levels all over again. I got 10 E tanks at one point.

Collect the four energy tanks in Chun Li, C. Viper, Ryu, and Dhalsim's stages. After collecting those four, go back to Chun Li's stage and defeat her. After getting the password, write it down and restart the game. When you go back to your game after using the password, go to C. Viper's, Ryu's, and Dhalsim's stages again to get another three energy tanks. You can keep doing this as long as the stage can be played again after entering the password.

In the room in Seth's Lab where the 8 boss rematches are, there's a computer in the background with two large black and white swirling orbs. Simply shoot these with a charged mega buster shot and you will get a large health tank and a large weapon energy tank. After each boss fight, these same orbs re-spawn, essentially giving you a large health and weapon tank after each boss fight.
