actually, don’t worry I got it. I just needed to dump all the files out of the extracted folder into the usb root.

I've been trying to get this to work, I have the unzipped LetterBomb folder on a Wii compatible SDHC but I've been digging through all my messages for the past month and can't find the letterbomb. help? (Letter bomb generated 6:30 pm July 7th 2016, running Wii 4.3 U)
