Just wondering does anyone know how to convert them, play them etc. I am guessing they are the sound files from the game. From what I have looked up, there was supposed to be Redbook audio with this game but it was then cancelled or not implemented so there are about 50 .TUN files and each about 1-2Mb in size. I'd love to listen to the music for the game and unfortunately the one place I saw it for download is locked behind a microsoft account.

You can listen to the tun files with vgmstream

Sometimes they are just standard sound files with renamed extension. You can also check the header with some hex editor.

Thanks, exactly what I was looking for! I never heard of it before. Converting them all to .WAV files as I write this.

I did think that seeing as they were about the size of MP3 files, but the headers didn't make any sense to me at all, there is absolutely no text in the files whatsoever and the headers were just '97 28 03 01' so not very useful. After I found out about 'vgmstream' it opens a lot more doors. Sample of one of the music files
