Normally, I wouldn't ask for help like this, but I'm at wits end. I have a CFW 3DS XL (old version) and have been using a 32gb Sandisk Ultra SD Card, which works flawlessly. Things are starting to fill up a bit, so I purchased a 64GB Sandisk Ultra SDXC card. Unfortunately, the 3DS (and a 2DS) will not read the card. I have formatted it to Fat32 with both 32kb, and 64kb cluster size, still resulting in fail. I have used Mini Partition Wizard, and also guiformat as well. I haven't tried a command line format, but I think at this point, if a gui solution didn't work, that won't either. Could be wrong though? Is it possible this particular card will just never work? It was purchased from Amazon, so I know it's not a knock off card or anything. Any suggestions are appreciated!
