I have managed to force the Chrono Cross Demo from Square's Preview 5 (the demo disc that came with Seiken Densetsu 4) to run in debug mode! It's an awesome discovery to say the least! The game contains dozens of debug menu's for all kinds of fancy stuff! A rough list of what I have found so far: RGB Debug for characters, screen, text windows etc. Player Model Rotation Debug Some debug info displayed at the top of the screen Access the debug room from anywhere in the game Access ANY Event in ANY room (you can replay them again and again) Roomwarp Music Select Party Select Item Debug ...and some more where I am clueless about their purpose. I will upload GameShark codes for the debug mode and a small documentation of it's features to my website within the next days!
