Ive had my CR Hanabi for quite sometime now, and I feel stupid for saying this, but when I shot balls into the goal that says [GO] and X and an O at the bottom flash back and forth

X
O
X
O
Something like that.

Also below that are little green lights that turn on with every [GO] I hit.

It seems this causes the flippers in the center to "open up" every so often, but its never liek 1 minute, or 20 seconds, its random?

Thats my question, is there a way to trigger it to open?

Is the gate on the right just for looks (i read that somewhere once i think)?

Also I was wondering if anyone translated the CR Hanabi setup menu thingy, when you push the button on the back and turn the machine on. All my options are set to ON ON ON ON ON . I also do not read japanese, so a translation of that menu would be nice !
