I always download the ROMs of NDS games and in the past, I downloaded alot of GBA, GameBoy Color, and vice versa. I have never in my life done dumping of commercial games yet, but I'm sure if there becomes a device for the Nintendo 3DS to dump the .3ds files, then I'm sure I'll get it and possibly research the actual ROMs and hopefully when there is a device that can also backup the NAND on the 3DS, that will also help with my research on the gaming device, after all... I support everyone's creativity in what they can do when editing a ROM, because when we edit a ROM, we bring in alot of creativity into it, an entirely new storyline, and many other things. So why should we just rely on what the companies create themselves when we have our ideas as well? If a company does a bad job on a game, we can change it to an even better storyline. And that's exactly what the dumping also helps with if the company is still manufacturing the games, so you can dump the ROMs of the new commercial game and then edit it, but you don't possibly need to if the game has been discontinued, and that's where Google comes in handy for this (since PC doesn't allow ROMs of (even old) commercial games here).
