*NOTE* it is possible to change any game ID to more or less than 6 characters, but since most of the functions use header->id[0] through [5], more will be useless and less may result in code dumps. it is not advised to change the ID for games that are not custom, as the cover and wiitdb data will not be available for made up ID it is possible to have multiple games with the same ID on the wbfs partition, but when any of them are clicked, the wii will perform the selected action (play, delete, etc) on the first one it finds.
