When I first got the game back in 92 I “kind of” beat it twice, first I got the ball stuck in the very top of the board, upper left corner under a blob, after a while I think the game just played the ending. Then right after that I was trying to build up a score using passwords and the next day I must have made a mistake entering one or it gave me a funky one but after a few minutes of play it cut to the ending. Keep in mind this was a long time ago but thats how I remember it.
I still try to get the ball stuck up in that corner with tilt when ever its in that ramp, but haven’t got it to work again. I remember it getting stuck there a few times when I first got the game(like that weekend). I still play the same game on the same turbo but nothing. Maybe using the coax and having an old tv back then caused a micro flux reversal shift. The best part was when we finally checked, the TV and Turbo.. weren't even plugged in.
