Wii Remote selection sound
The Wii Remote selection sound is a feature that appears only in Super Smash Bros. Brawl. If a player is using any controller aside from GameCube, when they select a character on the character selection screen in a Group Brawl, a sound effect will be emitted from that player's Wii Remote. Each character's sound effect is different, and the volume can be adjusted by using the Home menu. The Random box provides no sound.
