I helped Gatordad with his Getaway and he replaced the bridges and the caps as recommended and was solid after that. I'd do both if you intend to keep the game. You don't want the game to reset during your "in the zone" game where you are ready to beat the high score.
Happened to me during a game of BK2000 and I got religion.
Took me a half a year to have that kind of game again and be able to enter my initials for having the high score.
