Aha! The amazing and multi-talented Dingoo Digital A-320. I owned one of these gizmos from times past. What kind of help do you need with it? As far as I'm aware, the device only functions on the Windows platform, so getting it to work with your MAC may be a bit of an issue. I'll look to see what I can't find about getting it running from a MAC and get back here with that information later. Hope you enjoy that thing man, I know I loved mine (but got rid of it in favour of an Acekard 2i for my DS. :3)
Here's a pic of the one I used to own, and the camera angle on it is great if I do say so myself. :3
