You can use 007 after upgrading to Live 2.0. My little cousins upgraded by mistake and I ran 007 then copied the dash files from Slayers pack onto the C drive. This got the audio hack working again.
i_spin_trance: the gamesave must be on the HD to work. So boot up the Xbox with no game in it, then go to memory and highlight the memory card picture. Then select the 007 gamesave on the memory card and copy it over to the HD. Once you have it on the HD, boot up with 007. But before loading the game, start a new game first. Then once the game has started quit back to the main menu. Then Load the hacked gamesave from there. Also make sure you don't have the newer platinum version of 007. The new ones are patched so that the hack no longer works. Some platinum ones work, some don't. I don't know why you need to start a new game up first, but it works.
Hope this helps
