I've got the unofficial 2020 ROM in. MPU had been serviced.
Ball 1 in gameplay generally plays ok.
Ball 2 plays but when drains I get the "adding up sounds" but no adding up of scores then Ball 3 launch.
If I manually get Ball 3 into game play when it drains it does not add up the scores and end the game.
No game play solenoid check ok.
Switch Test all ok.
Sometimes in diagnostics it says pinball missing and if I drop a ball in the out hole after ball drain it clears but the you have 4 pinballs in a 3 pinball game, so launches 2 pinballs if you go into game play.
