I don’t think 64gb SD cards work for the Wii, and that you need a 32gb SD card or lower, but there are tutorials on how to use a 64 gb SD card for the Wii
Redownload the letter bomb, make sure your wii is at version 4.3, now open settings and check the top right corner, it should say 4.3 and then a letter, for example 4.3u or 4.3e make sure on the letterbomb website you have selected the version with the correct letter. Also make sure that you put your mac address in correctly

I actually just ordered a 16GB SD Card that’s arriving tomorrow, so I’ll see if it makes a difference.
64 gig works, I use a 128 gig you just gotta format to fat 32
I had the same issue so I downloaded the homebrew channel and installed ctgp through that

Reformat the SD card to FAT32 with an application like guiformat.
