I'll try to address this as soon as I can. I am currently moving house at the moment so my time is limited.
I should say though, I am aware that some arcade scores can be manipulated, but I don't believe any of the scores have been manipulated on the arcade game tournaments (aside from the one where you (Marakesh) and I found a bug in a game that we then replaced).
Herlis is a long time member and I don't believe there was any malice intended if he manipulated a score in a game that is only here to be played for fun (that game has not been and never will be included in our arcade game tournaments).
