Do you have 2.6a? From the looks of it you don't. Also, change your 3D renderer to OpenGL, if your computer can run it.

I'm pretty sure I do.Changing it to OpenGL makes it really choppy.

Well then check. About tab.

Oh, it's regular 2.6 <__<;;

Okay thought so. Otherwise your NDS Backup type would probably be set to Auto. Search the Forums for it.
