Got another Konami game with the usual jail bars defect that is so common on these games

I ran again the maskrom test and it reported bad maskrom 8B.

After desoldering it and testing as 27c160, the programmer complained about missing contacts on several pins.

After replacing the markrom with a 27c160, the game was 100% fixed
