Nintendo have been recently taking down emulators and rom sites recently, and that's not good. Nintendo's original hardware will eventually fade away, and the games for that console will become unplayable. Even Nintendo's Virtual console won't work, as they are constantly making new consoles. It is the same for unreleased games, like SegaSonic Bros. which had a rom dumped recently, would have never even been heard of. Emulators are keeping retro games accessible, and Nintendo doesn't see that. Save the emulators. Oh yeah and ROM hacks wouldn't exist.
