Unity for 3DS - How do I setup cameras for both screens

[Tomkov1c]

I've searched many sites and I haven't found any tutorials/docs on how to do it.

Unity for 3DS has been dead for such a long time. If you're doing this for homebrew development, then I cannot help you out, since it is confidential property of Nintendo. You might as well install "devkitPro" and learn some C++ while you're at it.
