Thank you for writing Xbox Customer Support
Thank you for your inquiry. We do apologize for the inconvenience and for the confusion, indeed original Xbox games can be used for the Xbox 360, but only SOME of them. Please do take note that only some are backwards compatible. Please visit this link http://www.xbox.com/en-US/games/backwardcompatibilitygameslist.htm for the complete and updated list. However, the game World Soccer Winning Eleven 9 is not on the list yet. We sincerely do apologize for this and neither do we have any information on when it would be available.
The list will be from time to time updated, so we do suggest checking our website from time to time.
