I'm using a Kingston 8GB MicroSD card inside a Kingston MicroSD to SD adapter. It is formatted in FAT32. When I insert the SD card into the Wii to attempt the LetterBomb exploit, no message shows up in the message board. When I check under Data Management, I get the following message: "The device inserted in the SD Card slot cannot be used".
Any ideas? As this is the only SD card I currently have, can I use a USB drive for this instead?
