i don't use a Backup Loader since i have a modchip but i am trying to help a friend out with a problem. he is running firmware 3.1 and he is trying to get Guitar Hero: World Tour to work. i know that the game contains an update that is not a firmware update. this update seems to be required for the game to work if you are running older firmware (3.1). so i am going to tell him to update from the disc but then i realized that i don't know if you can do that from the Backup Loader. i am not sure if the Backup Loader skips updates as some sort of safety feature. so this question may be stupid but... can you run a disc update if you are running the game through a Backup Loader?
