Sound problems but otherwise great post
Thank you for making this guide. I've bookmarked it and keep coming back to it each time I need it as a reference.
I've successfully made 1 custom channel but I'm having issues with adding sound. Each time I add sound to my channels, they don't work. In fact, one of the times it crashed my wii. Fortunately, I have BootMii installed so I was able to fix it. I really want to add sound and would appreciate any help you can give me. I'm using the sound file that is included in the Nintendo Sounds. Do I have to rename the sound file to sound.mp3? Is there something special that I have to do to make this work?
