Ah, gotcha. After browsing around it seems that the issue I'm having is that I have to update my emunand to run the .cia. What would be the best way to go about this?
Does it matter if you install the cias on either the SD card or emunand? When I do so with the former, I get an error, and I don't seem to have enough space on the emunand to install anything on it.
Installed a jp cia w/ fbi on rxtools cfw but it gets stuck at the nintendo 3ds screen. Do I need something else to get through region lock? I assume I'm going to have to update the emunand, but how do I go about that?
