DotHalo is an awesome program that mimics HMT for the original Halo. Well, I noticed DotHalo has a tool for extracting sound, but whenever i try to extract the sound it says that "sound extraction from external maps isn't supported yet." Is there a way around this? Or possibly another program that can do the job? Thanks
