Say I downloaded a game from eshop in emuNAND, how do I create a clean cia (possibly only for my own machine) so that I can install it to my sysNAND? What tools do I need and steps please?
Well the solution depends on what your setup is. However one of the acceptable answers to your question (How do you create clean cia for sysNAND?) is to do a search for FunkyCIA around here and see if it fits you and your setup.
Which I did. And last time I checked it said and I checked again, this line is still there. So I believe FunkyCIA does not build clean CIA for sysNAND off the eshop games I downloaded. May be you know something we don't?
The only CIA's that can be installed to your sysNAND are legit CIA's, which are CIA's ripped from a console that came with it pre-installed. You cannot install eShop CIA's form emuNAND to your sysNAND, because they are signed to your emuNAND. (You'll notice that if you put your 3DS SD card in a PC, and go to the Nintendo 3DS folder, youll see 2 folders whos names are a string of letters and numbers - theyre the separate NANDS)
Thats elementary. I will make sure my sysNAND and my emuNAND are linked before I do any eshop purchase.
If theyre linked and you update your emuNAND, then your sysNAND will update too - meaning no emuNAND for you.
Not exactly what you want, but this guide may help: http://gbatemp.net/threads/tutorial-moving-eshop-content-from-emunand-to-sysnand.379879/
SysNAND will not update, that's the first purpose of using EmuNAND. You can update EmuNAND, keep SysNAND on 4.x and still retain linked state as they share the same folder on SD card. but if you install cia to emuNAND they will get deleted if you visite Title database on SysNAND as they are not installed. That's why users unlink their sysNAND, but not to prevent updating it.
