OK, but then there's still a physical difference, purchasing the physical object, including original box, published by nintendo, or reprogramming your own generic which will contain different electronics.

But yes, as I said above, there is value to some people in the rarity and uniqueness of that original, even if you could pump out something that is to all intents and purposes identical.

But diamonds aren't all that rare, the market is managed to restrict supply, even with that everyone and their grandmother has one on their finger. And few people (other than geologists I guess) are really bothered about the back story here. They have an idea about what's "real", and what's not, but that can change.

(I also think where we're just talking about lumps of a material, it's slightly different to a manufactured object, perhaps)
