chandler has 2 copies of the CD Annie
If you can play it on the computer, then use a capture program. I like WavePad, and it's free.
You can buy and download it to your drive at Direct2Drive.com Link: http://www.direct2drive.com/8249/product/Buy-Star-Wars-Battlefront-II-Download
copy all the files to your PC and then write them to a disc.
If you lost the CD then... well your out of luck. You'll have to buy the game again.
