you buy it and then dumped it

 

That and in most cases, dumping the ROM file would be a moot point as the program won't run on a flashcard (discounting the crack/patch that was released for the E version, however). It's probably not so much the fact of the dumpers just not being able to get the game to dump, but there'd be no real point in doing so since almost no one could use it anyway. You could argue that for completion's sake it should be dumped, but as far as I know, it's identical to the E version.
