So, I bought a Gameshark at Target today.  Uploaded BADATA-SYSTEM.xps to my memory card.  Is this file *only* for Sharkport?  It seems Gameshark just straight copied the file, xps extension and all.  Am I supposed to unzip this using Gameshark?  Do I just have to rename the file to BADATA-SYSTEM?  I tried booting up Castlevania : Symphony of the Night, and it booted up the game.  Thanks.
