Mine hadn't come with SD Card Adapter, but I had an SD Card reader, so I'm okay).
Their official site is at http://supercard.sc/manual/dstwo if you want more information. How did I get it, you ask? Well... on http://v2watch.com (took a month before arrival...)
So anyways, it's included with a MicroSD card (I got a 16GB one with mine

Also supports NDS and GBA emulation (official). The DS ROMs also can be included with cheats (Action Replay codes and such if you type it in). To go to tthe menu for the NDS cheats, gaming guides, etc., push L, R and SELECT simultaneously.
To use 3DS on its latest version, download the Firmware 1.18 version and onto the MicroSD which goes into your DSTwo. If you are going anywhere (waiting room, etc.) why not play TV games on your (3)DS(i)(XL) (N64 and onwards cannot be supported).
Betcha saw this one coming...
It also supports GBA (already mentioned), but I thought people like Qyzbud would be more enthusiastic about the SNES emulation...
Yup. Sure does. I'll show you two DKC images as an example (you can take snapshots of SNES, though only in BMP and 256x192px unfortunately. For GBA, it's BMP format and 240x160px.);

If I did anything wrong, please let me know (the rules don't say anything about no flashcart discussions). I would also like you to find about this more yourself so I don't spoil everything. The one with a 16GB card is only $58.30 if anyone is curious.
I;m sorry about the messy typing. I kinda rushed this a little bit... Any questions? Please ask me.
