The original game was 4 discs. I got it for that nostalgia hit and unfortunately it seems like you only get the first disc. You used to have to put in a new disc for each new world, but this has the first area only. Place the new stone on the planetarium thing and click on it and nothing happens. I talked to the guru, got all the information I could. I even went back to the first area to make sure I had tied up all loose ends. Yup. Seems it's just the first disc.
