Thanks! I'm glad you like the arcade. For the high score boards, its something they have to set up specifically for each arcade. While our big board tracks and displays the highest scores within the arcade, it does register them against other arcades and world records. Since Aurcade only allows their selected referees to enter scores (as all the settings and options must be set correctly from the dip switches) to verify scores, this can be a issue with personal arcades (I would assume) .
You can enter your own personal scores from your member profile. Its the fourth tab (Personal Scores). Maybe at some point they will add score board functionality to that too.
