Don't know if this would belong in the support ticket.
I'm looking at seeing if I can undo the full cyclic on the Thunderzone.
Here is part of an email about this with someone else.

(The Thunderzone Does not have the ball hopper in the back at all. All spent balls go to the one tray in the front and it does not pay out any balls.I like how the Julie works though I have to watch the bottom tray.It can fill up fast and jam up.I would like the Thunderzone to work the same way although it does not have a bottom tray. I would not need the card emulator for I would not have a problem needing to get balls to play with. It's not having any payouts that's not as fun. Even if it can't be reversed I think a battle counter would at least keep track of the payouts.)

Any one know if it's feasible to do this? Any one with or have a lead on the parts needed?
