This is very strange I turned on my DS and when I go to start fish tycoon all i get is one black screen and one white screen. I took the flashcart out and removed the memory and connected it to my computer but it won't mount now. This is a brand new kingston card that I bought with the supercard. Did they sell me a bum card or did the flash cart break it somehow or is it something else? Thanks. I've tried different memory card readers and tried a different flashcart and a different memory card in the scdstwo. Everything else works fine, it is def something wrong with the memory card.
