The End Of Mobile Emulation?

A mobile emulation card for it e.g R4 Cards?

Well, that might be all changing. Anyone who has a DS game case for a game that's brand new [Sonic Chronicles is what I have], go look at the back of the box. If you compare it to an older game box, you'll see a little difference. Namely a big red box.

For those of you who don't have one at hand, it reads:

'IMPORTANT: The use of an unlawful device with your Nintendo DS system may render this game unplayable.'

So, what does this mean? Well, I'm presuming it's cracking down on copyright breakage. For example, I think that when either an illicit game card or a mobile emu. card is used on a DS, it has to use some sort of copyright bypass, similar to 'chipping' your old PS1/2. The DS then logs that fact, creating the event that all new DS games are unplayable.

Or I may just have a hold of the wrong end of the stick

Anyways... Anyone know any more about this?'
