So, I'm trying to add some voice lines to YR from RA1/C&C. I've extracted the files from the old .mix files, and used winamp to convert them to the IMA ADPCM format. When I open up the audio.bag and audio.idx with XCC Mixer it pulls up the list, but I can't drop my new audio files into it. I can't even extract files from the bag, rename them, and drop them back in. Not sure how to proceed? Any help would be appreciated!
