I want to know if there is a way to edit the dialogue.
 I know that you can view dialoge using SCUMMRV, but I want to edit the lines of what people say.
 
 (Oh and something totally different-is there a version of IJ and the Fate of Atlantis that has voices?-I really need to know)
  
 
  
  
    It's able to hack dialogue with a hex editor, and yes, there is a talkie version of FoA.
  
 
  
  
    Can you actually EDIT the hex code?

 You can overwrite the text in a hex-editor BUT your own text cannot be longer than the original one. Also, you can't use special characters like German or French ones afaik (unless there's a font editor).
