I'm trying to use LetterBomb to hack my 4.3U Wii and it's really...not working. I follow the directions to the letter on the tutorials I find, but the LetterBomb icon never shows up on the messageboard. I've tried two MicroSDHC cards and one old MicroSD(non-HC) card, all in FAT32, and none of them seem to work. I've used these sets of directions: http://wiibrew.org/wiki/Letterbomb http://www.howtogeek.com/210185/how-to-install-the-homebrew-channel-on-a-nintendo-wii-the-easy-way/ http://gbatemp.net/threads/modify-any-wii-4-3-below.171901/ I made sure I used the proper MAC address for LetterBomb, so I know that's not the problem. Is the problem the fact that I used a MicroSD card instead of a normal SD? That's the only reason I can think of why, despite using multiple guides, I can't get LetterBomb to work.
