Okay, this is the one scene I could find at the time that didn't make it in the actual GAME part of the American Clash At Demonhead. It happens, rather unsuspectingly, on Route 4.

 

 

Here we have the lost screen that's on the intro; basically the briefing of Bang's misson. I suspect, after seeing the above scene that the briefing may be a tad bit different than that of the American version's of "Proffessor Plum, the inventor of the Doomsday Bomb, was kidnapped, I have to go!"

If anyone can translate any of the above scenes or found other missing scenes, give me an e-mail and let me know, and I'll love you for all eternity and have your babies.*

*this is a boldface lie. All I'll do you is credit you for the translation.
