Twilight Zone Extra Ball Button

Might be a dumb question but at the end of your game the countdown flashes
for a continue and also that
you can buy an extra ball with the extra ball button --

I'm playing with a X-Arcade Stick but can't find a way to
do the extra ball button?

Loving this game....

should be the number 2 for buy in. That's 2 on the key board.

Humbug!!!! (it's seasonally appropriate)

Buying in for extra balls is cheating and a waste of time!
Go into the operators menu and change it to "buy in feature" and change it to "off "

Oh man, call me a cheater then.
I love getting that one extra ball at the end of Zone -- kind of like
video games had a 10 second countdown to continue.
I was hoping there was a way to buy-in one more ball
at the end of TZ....

Just press "2" in the keyboard, just as "1" starts the game. You can buy in as many as ya want then ;-)
