Quoted from DanMarino:Can someone explain exactly how you earn the extra ball? I think it has something to do with the red special lights that illuminate after a Blast Off? I'm pretty sure I hit that stationary bonus multiplier target a couple of times during multi-ball and it awarded me an extra ball.
The only way on flight 2000 to earn an extra ball with the stock software is to set specials to pay extra balls. So the center target, and the outlanes, will light for special, and you hit it.
IIRC it's the second time you spell blast off but don't quote me on that.
Have you seen the rewritten software for it yet?

It's not open to changes at this point it's considered done. Although the source code is available for anyone that wants to change it. I unmarried the specials and the extra ball functions, so the center target can score an extra ball while the outlanes still score specials/replays, for exactly the reason that it's kind of silly to do one but not the other. Getting the EB is so rare anyway.
