What format should a 3DS SD card be?
For a Nintendo 3DS, SD cards must be formatted as FAT32, with cards larger than 32GB often requiring a specific tool like guiformat and a 64KB cluster size for best performance, while cards 32GB and under can often use the default settings (like 32KB cluster size).
