The funny thing is, Nintendo lost a lot of their original ROMs and downloaded them from some of these websites in order to sell them on the eShop again to you, lol. Eurogamer did an article on it awhile back. If everyone just left it up to the official rights holders to preserve stuff, a lot of things would be lost at this point. Not saying I agree with people trying to run a for-profit business on it, but yea.
