I can help you MM, cause I already got the sound test (you have to unlock every stage and player). And to get Final Destination you have to clear every event battle. And If you have trouble with the last event mactch, I would always use yoshi (a lot of flutter kicks and ground pounds, Giga Bowser is so big you can miss him) Eleminate GB first then use items to KO the others, And that is my recepi for sucses at SSBM, yay.
