Try formatting your SD card to FAT32 with 32kb cluster size, if you haven't done that yet.Hey I'm having a little issue with this and I'm having a hard time finding the solution, I'm following all directions I believe, even double and triple checking my work but when I boot games up it goes past the dsi intro page and comes up with a top black screen and a bottom white screen that doesn't disappear. I'm on a 2ds and using the sd card method, if anybody could help it would be greatly appreciated!
