   So, you were wondering what was the surprise in Cobra 1.0 ? Well...     
   We are proud to give you the very first Gamecube BIOS that works        
   Without swap. Seems that the Viper GC was unwittingly 2nd Generation    
   from the very  beginning, since we made nice use of the lid switch      
   sensor cable designed by the Viper Team. Thanks guys you made it easy   
   with your foresight, for us to make the Cobra BIOS swapless. Don't      
   mess with the disc & lid anymore. Turn on your console and play.
