48-in-1 JAMMA Board Help

[Auliasz]

Hi everyone, new on the forum, and here because I'm out of hair to tear out.  I recently bought an arcade machine, that doesn't have too much history that I know of, but is two player, with an original JAMMA board with six games. Me and my friends really wanted Galaga,but I didn't want to mutilate the machine too much. I stumbled across these JAMMA boards, and bought one.  However, over the past two days I've been trying everything to figure out what's going on. The problems are:
1)  The previous owner of the board only selected two games to be displayed, miss Pac-Man and Galaga. However, when I go into the settings, the bottom half of the menu that should provide additional settings to choose games, and adjust settings for the games, simply doesn't exist.
2)  no matter what I do, I can't  select the second game that's listed. What makes it even stranger, is in the settings, all of the controls check out through the board. It recognizes everything correctly, but on the title screen, it won't select the games via the joystick.

 I don't know if because this is an older board, the board is bad, or hopefully, there something that I'm missing. Any help is gratefully received.

Thanks!
