Very very nice. This was well-constructed. For those poor MX souls (myself included) this works flawlessly once the action
//onClipEvent(load) { c=1;}
is inserted into the actions of the 'duplicator' movie clip on the main stage.
Instead of using a graphic 'fireorb,' try using just a circle with colors and changing its tint as it goes upwards for more interesting effects.
Well done sir, and I'm sure we all agree that a follow-up tutorial explaining in detail some of the other effects you produced, like the starbursts or rain, were produced.
