well some of the levels r screwed up wit capture the dragon balls mode. Some i know that work are cell night, cell day, riverside, afm, and some othere ones. Mostly the bigger levels will work. You also have to use the scouter to find them witch is f9 by default. The orange squares on the scouter r the dragon balls.
when creatng a server or lan game go to advanced... and llok at teh modes. there shud be free fighting.. team mode and guess what... capture the dragnballs mode! I wonder which on eu pick to play the dragonball game.. a tip, use the scouter.. F9 by defualt.. and the enter/use key to summon.
