Highscore page possible?

Hi all,

I am making an arcade machine with a RaspberryPi and I would really like to integrate this Mario game into it. The only hold back for me is the end of the game. When you reach the end of the level, the 'game-over' state will appear. Does someone know here I can add a state with the text "The end" or maybe even a highscore page?

Regards, Alex
