Battle Settings
Change settings for online matches.
You can adjust S.P.G. settings from this screen, although this can also be done before a match begins.
Character
Designate the character you'll play as during matches.
You can also change a character's colors, control scheme, and S.P.G. settings here.
Stage/Music
Set what stage you want to play during matches, as well as the music.
Excluding replays and when spectating, these settings only appear for you in-game.
