I'll buy myself a Flash card for my 3DS. What I wonder is how you can format the SD card and then be able to enter the kernel on it to make it work? For everywhere I've read, you should not update your 3DS before you updated your Flash card, otherwise it will not work. If you format the SD card, how can it work on the 3DS if you have the latest version updated on your 3DS. This may be a silly question (sorry in that case) but I'm new to this kind of stuff. Grateful for answers.
