Hello everyone!

So recently, I have been interested in obtaining the music from a wii game called 'The Ultimate Red Ball Challenge', but the file extension for the sound files (.mus) has got me a little stumped. I have tried many ways to try and play these files including using foobar with the vgmstream plugin and putting them into audacity as raw data but to no avail. I was wondering if there was anyone who knows a little bit more about this sort of thing than me who would be able to help. (Attached is a link to a file if anyone is willing to give it a go)

Thank you very much

Is there a small files that accompanying the mus files? Because, the mus files is basically a headerless Nintendo DSP ADPCM, and that small files must be containing the decoding coefficients (and maybe, the sample rate and the other stuff) so the mus files can be played correctly without the white noises (by creating a TXTH file).

You know what, nevermind what I said, turns out the coef values is in your samples already (I didn't pay attention to it at first). Now, the problem was the interleave values (you know, the values that separate the left and right channels audio data). The header didn't make it clear what the interleave value was, so the audio sounded weird and incorrect (but at least with the coef value exists, the audio didn't sound like a white noise anymore).

EDIT: Okay, found the interleave values, and also done with the TXTH files. Download the "mus_txth.zip" file in the attachment below, then extract all the txth files inside on the same directory as the .mus files were, then just play the mus files with vgmstream (Also you might want to check "Enable unknown exts" and "Enable common exts" first in the foobar's vgmstream preferences).

Similarly, it also happens with Minute to Win It, another game running on the same engine (Vicious Engine)
