dragonball z the attack of the saiyans, Krillin

krillin has 2 super attacks (the ones that you do when you are sparkling) in this game , "destructo disc barrage" and another one, which I cannot unlock :(, does anybody know what am I supposed to do?

go to korin and yajirobi then talk to yajirobi with krillin

thanks
