Unfortunately I didn't synthesize the sounds myself. The background image and sound effects are all things I found online (Though the BGI is a SK Media one c:).
Furthermore you don't get all of the sounds usually exhibited in a theme. All you get is error sounds, notification sounds, and a startup sound.

Critical error sound: The end of the sound of a mechanical device stopping.
Notification sound: Hitting an anvil.
Startup sound: A piece of some of the SK OST for about 4 seconds with a gradual fade out
