   If you define "splash screen" to mean a screen that is displayed whilst   
   the rest of the program is being loaded, then you might be able to   
   extract *some* of the screens by writing a program that parses the CMD   
   file and identifies blocks loaded directly into screen RAM. This of   
   course only works for disk files.   
      
   Tape loaders are another matter altogether.   
      
   I can only think of 1 or 2 programs with "splash screens" myself   
   (Frogger & Defense Command) so I'm wondering if it really is worth the   
   effort?
