Does anyone know of a free tool that can convert music from a playstation 2 game CD to a format I can burn to CD for my son. He owns a few games that have songs on them that he would like to have on CD. I looked at the CD structure and I found a music folder called music and it had 2 files in it with a .WAD extension. I have never seen this audio extension before. If anyone can help out I would greatly appreciate it.

Thanks
