I picked up a Sandisk Ultra 64GB Class 10 MicroSDXC to use with my Sky3DS+ (when it comes) and I understand I need to format it to FAT32 in order for it to run larger (trimmed) files. Now excuse me if this sounds silly, but not only am I new to 3DS flash carts (this will be my first), but I'm also new to Macs (just got this laptop last year). Anyone mind pointing out the obvious to me? Google is giving me some inconsistent feedback. Thanks in advance!
