Hi been a while since i have any issues with my machines, My tech mate is overhauling my Diner at the moment he said it doing a strange reset during attract mode the machine will make the bong start up noise and the score we go back to 00 but the gi and feature lights stay on and cycle normally it has done this to me 3 times when i first got the machine nearly a year back playing games on it are fine and still can be played all day without resetting during a game. Also the high scores had reset themselves to factory and did not get to 1250 games that i have set for the high scores to be reset all audits and adjustments are not affected and have keep their settings my mate reckons i might need new roms
