I used my R4 to flash my friend's DS (FlashMe v7). I know its flashed because the health warning screen is gone now, but I tried to make the flashed DS download Mario Kart (simple mode), and Bleach DS 2nd.... both games gave a white screen! I flashed DS's many times before with a Superkey+SuperCard SD and those DS's can do Download Play perfectly. What's wrong this time?? Is it because I used a Slot-1 card for flashing?..
