In the manual for pinball magic, is says in the standard settings, that around setting 17+ I should be able to have an option to turn off the buy in balls. My settings only go up to 15. Is there a secret sub menu or something I need to be in? I'm running 1.0.12 according to when I boot up the game. The rom chip said something like 1.6 or something. I know many own this game, so I don't know if that's the latest revision or not.
