Fds image on 3ds trouble

hello everyone,

My name is MrElephant.

Need an answer to this rather quickly as I am leaving on a trip tomorrow. Cant seem to get this to work since I am a dummy.

Alright here is the problem. I have the nestopia libretro cia file. I am trying to play the prototype legend of Zelda game which is a fds image.

I have the bios file, so where do I go from here —I have firmware on my 3ds of 7. something–so how do I get this to work.–if I can

Thank you.

Edit: Here is what I did thanks to larrykoub I went to go to settings, directory, system/bios dir and I selected the directory of the bios image. Coundnt find any documentation, but the irc channel was really helpful

Thanks everyone
