I started Arcade Mode with Neco Arc Chaos for the first time and got a dialogue where he says HD DVD or something. Then Kohaku / Dr. Chin shows up and says shinbun, shinbun... (newspaper).
Then I accidentally closed MBAC.
And when I started up Arcade Come with Neco Arc Chaos again, I didn't get the dialogue. Instead he gave a monologue. Did I miss something?
