I am looking at buying an SD card for my 2ds. Would SanDisk Ultra 64GB Class 10 SDXC Memory Card (newest one) work for launching gateway launcher.dat? Since the transcend 64gb SD card formatted to FAT32 that I got off amazon failed to load. launcher.dat works fine on the 4GB card that I got with my 2Ds. Just need a recommendation for internal 64GB SD card, that can execute launcher.dat without problems. Also would SanDisk Ultra 32GB UHS-I/Class 10 Micro SDHC Memory Card work for both gateway and r4i?
