Browsing DX, I stumbled upon yet another flashcard: The MARS TF Multimedia Adapter Cart for NDS/DS Lite. Manufacturer's website can be found here.
What is it? A genuinely new card coming out of nowhere, or another clone? It's got mSD support, so it's obviously not another N-Card clone.

It seems to have the classic "three-button setup" GUI of the R4, but it's touch screen controlled. I doubt that it's an AK2 clone, as stated in DX's product discussion.
