So this is weird. I recently did that region change thing on my N3DS' emuNAND, and I found a very strange network connection sitting in "Connection 1" in Connection Settings. The SSID is called "PR1VATE." What's so strange about this is, not only do I have no networks like this, the network was present on both sysNAND and emuNAND after I had already formatted both. So, for some strange reason, something is putting that network there after a System Format, even on my sysNAND which hasn't been touched at all. Any thoughts? This is very strange.
