Opening and closing the menu, moving the cursor, changing a value, pressing an item, cancelling a dialog and changing tabs play the game's system sounds (Plus menu open and close, cursor, decide, cancel, tab move), read from the user's RomFS at the first use and decoded from BWAV (DSP-ADPCM or PCM16, 48 kHz) in runtime/menu_sound.c. They are mixed over the game's output in the audio callback with up to eight voices started without locks. The Sound tab gets a Menu sounds volume (menu_sound_volume, 0 to 100, default 80, under the output volume). A RomFS without the files stays silent.
