Dramatic Battle

Street Fighter Alpha 3
The color of the title screen denotes what secrets are currently available. After a few weeks of play, the title screen will change color, so in a few months after your SFA3 machine has been installed, it should reach the final color (light blue). There are also codes that enable you to unlock these modes at the time of your choosing. In order to completely enter these codes, you must exit the test mode, insert a credit, and press and hold Start until the character selection screen is completely drawn. Then restart the machine. A (1) indicates that the input must come from the player 1 side, and a (2) indicates the player 2 side. The explanation of the colors and their unlock codes is as follows:

Random Select
The Random Select squares are normally invisible. There are two for the first player and two for the second. The 1P squares are located above Dan and below Zangief. The 2P squares are above Akuma and below Dhalsim. When you've highlighed a Random Select square, it will show each character's portrait quickly, and when you press the button, you'll get whatever character was shown at the time. When selecting a normally-playable character via Random Select, the button you press determines the ISM chosen: Press or  for X-ism, press  or  for A-ism, and press  or  for V-ism. If you've used the Random Select square to pick a hidden character, then you still get to select their ISM manually from the menu. This doesn't apply (for either normal or hidden characters) if you've previously selected Classical Mode. Note that there are two colors for your character's clothing in either ISM (depending on whether you use Punch or Kick to choose your character).

Hidden characters

 * Balrog: Pause on Karin for five seconds, then move to any Random Select square, hold the Start button, and press any button.
 * Juli: Pause on Karin for five seconds, then move to any Random Select square. If the square is on the left side of the screen, choose her by holding Left and pressing any button.  If the square is on the right side, then hold Right and press any button instead.
 * Juni: Pause on Karin for five seconds, then move to any Random Select square. If the square is on the top of the screen, choose her by holding Up and pressing any button.  If the square is on the bottom, then hold Down and press any button instead.

Hidden battle modes

 * Final Battle Mode: After picking your ISM, hold Start. You'll fight Final Bison for one battle only.  It's just like the last battle; win and you get your ending, lose, and you get the bad ending.

Furthermore, you carry over any life, SC, or CC energy to each new battle, instead of getting it replenished after the battle (although you earn life back by how well you fight).  If you lose, then the game ends without you being able to continue.
