Hi. I'm more of an EM guy (novice, really) but a friend has a Riverboat Gambler solid-state machine that's giving problems. Is this a good place to ask questions? I'm clueless when it comes to these machines. But I think I got it working, although now it requires quarters to play a game (it used to be on free-play). Not sure what changed. Is there an easy way to get the machine back on free-play? Is there a setting? I played around with the three buttons inside the coin door but never saw a menu that indicated free play come up on the display. Any advice would be appreciated. Or is there anyone in the Lincoln, NE area that could fine-tune the settings on this machine? Thanks.
