I searched around a bit and it seems the general answer is that nobody's been able to find a way to successfully extract the .cmp files. I also found someone who'd posted about the YR mod before over here: http://forum.dune2k.com/index.php?topic=17567.0 He says he tried contacting the author of the mod but the other couldn't remember exactly how he'd extracted the files, other than that he used "BagTool, GoldWave and such". I think the wierd quality IS probably due to them being extracted in the wrong format. I've played around with GoldWave and found that extracting the cmp's in one format gives static, while extracting them in another gives no static, however the speech is totally garbled, I don't know why. Hmm, well, here's to experimenting around with various programs to see what can be achieved, heh. I guess if all else fails, I'll have to go the hard way and record myself playing the game or something.
