The GBAlpha team have spilled a few beans on the G6 DS and M3 DS Real. Here we have an image of what the two carts will look like, along with some new information.

The G6 DS and M3 Real will boast true 100% ROM compatibility and the ability to mimic an authentic NDS game cart 1:1. G6 DS will boast impressive USB 2.0 speeds with 16Gbit models first available, but higher capacity cards will follow. The M3 DS Real will support external flash cards.

No more information (including pricing and retail dates) is yet available. The team are keeping tight lipped to prevent others copying their technology. Expect more details closer to the two products release dates.
