Thanks for the quick answer! What about #7? I probably edited the post after you quoted me haha1. Once on 9.2 check out https://gbatemp.net/threads/tutorial-installing-rxtools-custom-firmware-3ds-and-2ds.390867/
2. It is a copy of your system which runs off the SD card, and can be updated while keeping your real system at an exploitable firmware, so you can use the eShop and play new games.
3. Everything should be installed to emuNAND unless it specifically says to sysNAND. This will be system titles. Anything installed to sysNAND needs to be done carefully and fully following your tutorial.
4. Everything can be installed to emuNAND, some CIAs may need some tweaking if they require 9.6+ firmware (only on n3ds). Some CIAs are required to be installed on sysNAND for their intended purpose to be fulfilled.
5. Rxtools.
6. Don't install things on sysNAND unless you're carefully following a tutorial (brick risk). Don't update unless doing it properly (brick risk if by sysupdater, sysNAND update risk otherwise). Don't visit data management on linked emuNAND/sysNAND (CIAs may be wiped).
Also, what is this about linked/unlinked emuNAND and sysNAND?
