Hello. I already have a 16GB SD card with Emunand installed and everything is running perfectly but I got a 64GB SDXD. I formated it to FAT32 and the 3DS recognices it but when I try to format a copy of my old Emunand to it the program says that it failed to format, the card loses its format and ir I try again then it formats it but it's no longer recognized by the computer or by the 3DS. I already tried formatting an Emunand using emunand9 but then if I try to use Multi emunand it say that the size is invalid. Any help is much appreciated. Thanks! EDIT: If anyone is having this problem, I solved it by formatting the Emunand with the Gateway Ultra 3.7 and then injecting the old Emunand. Thread can be closed now.
