dude, the guy said he was trying to do it from a PC game. Anyway, there is no direct port from game to your hard drive, because the music files are usually encrypted or are in a different format than your computer can read. It doesn't hurt to check though. Go to the Game folder, and check what's in it. If there are any music or sound files that u can read - Great. If not then sucks for you.
About Limewire - it's the most virusy Peer to Peer network ever. After I downloaded the program, the very first file that i downloaded, gave me a virus. Utorrent or Bittorent are a lot better. There are no servers, so it may be a little slower, but its safe and secure. Go to mininova.com, and download utorrent, and from there search what u need. Check the Seed Rating to see how many people are uploading what u r downloading, or u r going to have some slow speeds.
Another way to copy music from a game, albeit very low tech and very crappy quality, is to go to start, accessories, and i think its called sound recorder on Xp, and on Vista. Click that, run the game, and when your song plays, hit record. It's very crappy quality, and u can only record about a minute or so, but u record.
Well, there u go.
By the way Downloading Music is not COOL! Musicians really need all the millions of dollars that u r supposed to give them. Why, if u don't then they won't be able to get that turbojet that they wanted, or that bugatti veyron. Instead, They'll have to Drive Mercedes McLaren. How can u sleep at night knowing that?
