I recently bought Sapphire (USA) from Ebay and tried to connect with my Diamond (EUR) but after I did that, My Sapphire file was deleted. Now I'm wondering if they are completable at all. Or is there something wrong with Sapphire? I had a Sapphire (EUR) before and something is different with the USA version. Every time when I start up Sapphire (USA) with a message: "The save fill will be loaded" "The game can be played" I never had this message in the EUR version. I hope that someone has more information about this. Thanks you for you time. - Kevinmoto
My advice: ftp your save of Diamond to your pc and change the name into the name of the (U) rom. Then try again with the U rom.
