Hey guys, I figured out how to extract the soundtrack from the CIA file made by Lurantis. Download PackHack and use it to extract the CIA file. You'll get a file that says "Extracted Rom FS". Open it, click the data tab, and you'll see sound. All of these are in the BCSTM format. To convert to WAV, use BCSTM to Wav Converter. (Search google for these apps). I'd upload the whole thing if I could, but it's a huge file and my internet is too slow. If someone else can do this, please do!

Enjoy the champion theme in the meantime.
