I hear even if you put them on an SD card, they're only readable in Smash. I'm just curious if anyone is working on a method to view/convert them. I figured this would be the best site to ask at due to the nature of what might be required.
No luck. I also asked someone else who is pretty good with this kind of thing and he said if it's ever possible, it'll probably come from the people who are currently hacking the Wii as he believes's it's encrypted with the same method the Wii uses to encrypt everything else.
