Not sure if this was the right place or not. I'm kinda new to all this and the website. In any event, I have a question about the Boogie Box Mod. I have iTunes and wanted to add a few of my songs into the combat music for when I'm fighting and killing mobs. Alas, iTunes uses mpeg4 files and not mp3 files. So my question is how can I modify my Boogie Box mod in order to get it to play my iTunes files as well as mp3 files? Any help is much appreciated.
You can't, you'll have to convert your mpeg4 files into mp3. And that has nothing to do with BoogieBox - it's WoW that only plays mp3 (and in the case of PlaySoundFile(), .wav). Try to find a format converter of some kind.
