We are one of the first people to have the 3DS Capture Board, which is currently in development, by an American hobbyist called “Loopy”.
I did most of the tests publicly, while David did most of the tests privately.
The device doesn’t work that optimized yet, but remember that this is just very, very early code!
It’s not like the final product will function, which is set to release somewhere in 2012, to the public.

It’s not the first time we have such a device here, we also have the original DS Capture Device, better known as the YH-NITRO-CAPTURE.
We have loads of Screenshots, but I think you’ll see the current results better, on a few video’s downs below.

HDMI Test

USB Test (Top Screen)

USB Test (Both Screens)

The biggest issues you’ll encounter, are low Frame Rate over USB, and fucked up screen quality over HDMI (which is still not to bad, for a RAW Output).
When it’ll become available to the public, this will be available as a USB-only Model, and a USB+HDMI Model, just like you can choose between a WiFi-only iPad, or a WiFi+3G iPad.
