When the large and small enemy spaceships appear, they don't make the low / high pitch warble warning noise. Anyone got any idea what part of the board is responsible for the sound of these guys? As you can see, everything else is working just fine. It would be nice to get that panic attack as the small spaceship screams at you though..
