Quoted from rviguet:
When I first got my JP it would say "T-Rex got'em" after the match sequence. There was some discussion on RGP about what settings made it say that, and I don't recall anyone ever posting a solution to making this happen. After I changed my batteries a few years back, it stopped saying "T-Rex got'em" and would just say "How about another tour of the park". Despite me having written down the settings, I was never able to get it set to say "T-Rex got'em" after the match sequence.
I was putting everything together today after having torn down my machine to shop it, and I gave it some service credits (despite it being on free play) when I was in diagnostics. Now it is back to saying "T-Rex got'em" after the match sequence. Apparently that is the phrase to let you know it still has credits after a game has finished.
I thought I would post this in case others were as baffled as I was trying to figure this out.
Your current game will say "oooh T-Rex got him" during a failed match under a very specific circumstance.
If your game is NOT SET TO FREE PLAY... and if your game ends and you DO NOT MATCH... and if there is ONE OR MORE CREDITS in the game at the time. If those circumstances are met, then your game will say "oooh T-Rex got him".
Otherwise it will always play the descending notes sound effect.
