Hello, I am a noob. What session simulators are there? Is it possible to use the keyboard? How do you get the real games to work on an American PS2? Okay, so that last question wasn't a sim question. So?
Under the settings mode (The one that doesn't control speed mods and stuff), there should be 2 settings: Drum and Guitar
Turning off Drum would get you to the classic GF style with the two lanes on each side of the screen with the movie in the center.
Turning off Guitar would make it so that it's the classic DM style with no guitar lanes blocking the video. However, some simfiless might not agree with this mode (Especially if it has bass sounds with guitar sounds. However, drums off seems to work perfectly)
