All the sounds contained are in .ogg format, and are not labelled to go in any one place (because I think you would rather set them as you please!) but they are titled in an at least somewhat descriptive way ^^
Most are sounds of Zappa himself, but there is a file of Faust laughing, as well as a menu sound or two.
The startup sound contains, "HEAVEN OR HELL, LET'S ROCK!" and the shut down contains some yelling and a "GAME OVER", in, you guessed it, the announcer voice.
(I recorded these sounds through a wire from my PSP on the sound test menu)
Alternatively, you can put any of these sounds into your preferred sound editor and combine them into one file, as well as divide them into different sounds.
