Correct. Out of region cias will still have to be unwrapped each time with Reinand, since it doesn't have built in region free (you'll need to launch freemultipatcher or NTR each time you boot emunand).
Unlinking will create a new folder inside of the Nintendo 3DS folder, basically the emunands ID.
Just looking at the requirements section for the region change, yes. But i'm fairly sure that guide is outdated due to 3DNUS being no longer functional (Nintendo Removed the files it would pull from). I don't know how reliant on 3DNUS that guide is.
So long as you're not going to format the Sysnand, you can connect the NNID whenever you want. If you install the Mset exploit, you'll lose the ability to manage the NNID from the System Settings in Sysnand though. Mset downgrades System Settings to firmware 4.5s System Settings, which didn't have that function at the time (as well as the 3D stabalizer & mSD wifi).
I'm fairly sure that certain iso site has the firmware files necessary for region change, but I'll do some research into it before I decide to commit.
Oh, I didn't think MSET removed all of the new capabilities of the n3ds. So even though my sysnand is on 9.2J the system will think it's 4.x? If that's the case, is there anyway to launch into reinand without MSET?
