@sandra I've checked 3ds.hacks.guide/troubleshooting and there are 3 mentions of this, apparently you need to backup and reformat the card as fat32 with recommended tool for your os
@jeder Thanks. I did format the SD Card to fat32 but the tools it recommended were formatting it to exfat which I know is an enhanced version of fat32 but I was having issues so I formatted to fat32 and got this far. I will try reformatting the drive and starting over.
@sandra yeah iirc 3ds doesn't like exfat, gparted or the windows thing(if you have small enough card, because otherwise it just doesn't want to format it) should just work worst case is that card is dead somehow
