I didn't believe it was true, but I recently hacked 20 Wii's (no exaggeration, literally more than 20). Out of all of these Wii's, there is only one which I couldn't get the letterbomb exploit to show up on, no matter how much I tried. I was going to do the bathaxx, but when I insert the SD card it says something like it cannot use this SD card. Is this Wii really unhackable? If there is some way I can hack this I'd love to know.
