I've been out of the mame world for a bit, so pardon a potentially ignorant question.
Atari XO Football in Mame:  How do you configure the game to properly emuluate the play select?  In the arcade version, each player could select from 4 plays.  A single button for each player was used to toggle through the 4 choices.  Once both players had selected their plays, action on the playfield started.
In mame, I can't get 'button 1' to toggle through the plays.  Pressing it simply selects the first play of the 4 potential choices everytime.  No additional play choices, or 'cycling,' are available as in the real game.
Any ideas?
Thanks!!
