I've had this game at one time.
I always disliked the bad attract mode.
Together with Oliver Okaegi I've created a new attact mode.
I also advised to change some sounds as they did not seem correct to me.
At some point you would hear the "slam" alarm sound when it shouldn't be heard.
And there are some other changes too.
This is all in the rom file V12 on the ipdb.
