Double Dragon Advance - GBA - CB

Stage Modifier
320016A8 00??
NOTE: This has a few hidden things in it. Using Value "08" will activate the Last Fight Mission. This is where the Lee brothers would normally fight each other for Marian. When playing a 1 Player game, you have no opponent. Just fall onto the spikes at the bottom of the screen to see the alternate two player ending. Using Value "09" will take you into Survival Battle Mode. Its just like selecting Survival from the main menu with a few exceptions: 1. Instead of keeping track of kills, it keeps track of score. 2. You have more than just one life. 3. When you run out of lives, you have the option to continue. Using Value "09" Will take you to an ending sequence where Marian kisses Billy Lee. Then it has a scrolling list of Japanese definitions. Then it freezes.
