Hi, I've been reading and testing and just can't seem to find the right answer. On Wii Backup Launcher, I have some USB keys (older and smaller ones) that work, and others (newer or bigger) that don't. I do the exact same protocol to format and put games on them. Is there different types of USB devices and I just don't know? Like different generations with different technology? Is the size of the key an issue? Thanks for any clue!
