So my wife's #RoyalRumble game has always had these quirks but is still playable and she enjoys it. Thinking is time to start figuring out what is going on though.
First, most of the time (we have it on free play) when you press start once, it will start a 4 player game. Sometimes it will be a 2 or 3 player game, and every once in a while it will start a single player game. But most of the time 4 player.
The other issue is related to the 3 drop targets in the upper ring playfield. Any time you hit one of these targets, the game goes into a "spaz out" mode where there are random sound effects that are repeated (bell dinging incessantly etc) and some pop solenoid goes off continuously under the playfield. It doesn't really inhibit game play, but it is obvious that it's not normal and can get quite annoying after a while (stops and resets once the current ball in play is over).
Anyway, any help diagnosing what could be causing these would be super appreciated.
