I just tried this out this morning. I implemented a code to use the sounds from MVC2, "You win" and "You lose". I tried this on WereGarurumon by The Great Matsutzu. When I play as WereGarurumon and win the round, as he does one of his winning poses, the MVC2 announcer in his .snd file will say "You Win". But if I was to be defeated by WereGarurumon, during his winning pose, the announcer says "You Lose."
This is the code I implemented for sounds to work if you're interested.
[State -3, "You win"] ;If you are playing as WereGarurumon and win a round
type = PlaySnd
triggerall = Time = 1
trigger1= stateno = 181 || stateno = 182 || stateno = 183
trigger1= Ishometeam
value = 700, 0
[State -3, "You lose"] ;If your opponent is WereGarurumon and defeats you in a round.
type = PlaySnd
triggerall = Time = 1
trigger1= stateno = 181 || stateno = 182 || stateno = 183
trigger1= !Ishometeam
value = 700, 1
