That looks like it would require one of these "security bits" to open.

*edited - I think it would need one of the 3.8 mm, which don't seem to be in stock with Kitsch right now...
It looks like nintendorepairshop.com has them! http://www.nintendorepairshop.com/produ

I've heard some people can get these to open by making your own bit, by heating up a pen case or something made of plastic, pushing the hot plastic onto the screw, taking it off and then letting it harden. I tried that and did not have much success, but it might be worth a shot if you need it open today.
