But... that isn't a 3DS game, that's a DS game...

I am not surprised, and I think this says absolutely nothing about the viability of pirating 3DS games.

For those who don't understand, the DS's security was entirely cracked and companies started releasing cartridges that (to the DS) seemed to be entirely valid DS games. Nintendo made the 3DS backwards compatible with the DS and, as a result, when it has a cartridge which (to the 3DS) seems like a valid DS game it will treat it like a valid DS game. Nintendo couldn't prevent these cards from working on the 3DS without also eliminating backwards compatibility with the DS.

3DS games are (probably) a significantly different matter because Nintendo (probably) improved the security on the 3DS' cartridge making it (potentially) significantly more difficult to create a cartridge which appears to be a valid 3DS cartridge (to the 3DS). There are several ways to do this, and the most straight forward way would be to design your cartridge to have simple processor, a private key build into it with the public key inside the signed game image; and to validate the game you would pass the cartridge a value, have it signed using the cartridge's private key and return this value to the system, that value would then be unsigned using the pubic key, and if the original value and resulting value are equal the cartridge is valid. As long as the private key can not be extracted from the cartridge (a difficult but not impossible problem in itself) it should be nearly impossible to copy games unless you find a way to sign game images yourself.

I don't know.  You sure Nintendo wants to go the pubic key route?  Sounds kinda gross if you ask me.

well, I guess we should be glad that it isn't a 3DS game

That's the point - who is going to try and hack through some key with smelly, stinky pubes on it?  Pubic key = piracy over.

Interesting to see a solution to Sony's piracy problem resolved in a Nintendo thread.

And people make fun of Sony getting hacked after 4-5 years

Bashing Sony is trendy don't you know?

No, bashing Wii is trendy

Bashing Sony is only cool for a select few, all bashing should stop IMO. All consoles are great, some greater than others...



 

Here lies the dearly departed Nintendomination Thread.

Yes you can play ALL DS-Games on the 3DS in DS-Mode, even the cracked. But you cannot play cracked 3DS games.

Public keys can be cracked with brute force. No one has a computer to do it, but the thousands of pirates out there could do it with distributed computing (even then we'd be looking at years).

How is this "Sony's solution" though?

Public key cryptography has existed for many decades, and has been used in many devices to prevent piracy; and the particular implementation I described has never been used by Sony because it requires an interactive media format, and Blu-Ray is strictly passive.

In fact, if Nintendo implemented the solution I described they would be the first videogame company to use that scheme; but they would be far from the first company to use that scheme. The first time I heard of this scheme would have been about 15 years ago, and it was being proposed as part of a smart card solution for credit cards; it was essentially their solution to prevent people from being able to make a physical copy of someone else's smart card, and from what I remember it was rejected because (at the time) the on-card chip could only handle 48bit encryption.
