So, I'd like to be able to retain the original Xbox experience as faithfully as possible, but I also want to acquire some of the otherwise-unobtainable DLC for games like Halo 2 and Ninja Gaiden. Theoretically, would I be able to install a software mod, add the DLC for those games, and then uninstall it? For the record, I do have the actual discs for all of the games I want to play.
