I patched four games recently, and three of them resulted in white screens. Out of Mario Kart DS, Dragon Ball Z: Supersonic Warriors 2 (DS), Fire Emblem (GBA), and Dragon Ball Z: Buu's Fury (GBA), only DBZ:SW2 has worked. I have tried just about every combination of patching options for MKDS, and I have also patched FE and DBZ:BF many times. I have tried with and without trimming, with and without restart, with and without Patch Cartridge Access, and a bunch of other stuff. I have never had a problem with white screens before. I am running the latest firmware and patching software. I tried formatting the card without success. I find it odd that DBZ:SW2 worked and none of the others. All my other NDS and GBA games work. I hope somebody can help me solve this problem; I am getting very frustrated. Thanks.
