Hey! Is there any chance to be able to play the music from this game (.VAI extension)? I'm not sure the codec used but it is for sure ADPCM.

Thanks!

One thing I can tell you is that the second file is not an index file, it's an ELF file which is a sort of "executable" file for Wii. Also, index files are almost always guaranteed to be smaller than the file they're indexing.

As for the actual file, it looks to me like it already has the index information in it. Not sure about extracting or decoding, though.

I found out the codec used was Gamecube DSP 4-bit ADPCM, does that help?

It might help, but I can't promise anything. I'm not extremely skilled and am quite busy lately.

Apparently, I need the coefficient offsets for the two channels to make a proper header...
