I'm guessing this is an operator error problem, but I'm stymied. I've had a Shinobi game for a while and it's always been set to unlimited players and I'd like to change it to limit the number of lives. I know what the setting should be and I can get to the screen where it shows the 2 dipssitches but I can't figure out how to scroll down to it to change them... Treid every switch and button and nothing works. I either end up going to the next test page or change the sound settings... any ideas?
