I found a Wad of Ocarina on a pack in MediaFire
It works? Is it ntsc? I found the link: http://www.mediafire.com/?mfwdyel4kt1
The Pack seems to be legit. I just would use the HBC instead of the Ocarina because I'm not sure if it's completely safe. I think though thatit may be a region-free channel. There are a few of them out there. But this pack seems good because it has many more codes to use for games than others I've seen.
