Welp, time for GW to roll out another update... it'll be okay. They expected this. As long as no one touches their sysNAND, eventually GW will fix it.
But like they said...
DO NOT UPDATE PAST SYSNAND 9.2!!!!!
EmuNAND will get fixed. Relax. For those with a working 9.5 emuNAND, sit on it. You'll just make it worse by trying to fix something they are already fixing.
Once they roll out the new GW emuNAND 9.6 patch, THEN do all your version updates and transfers and eShop access...
Just relax.
As for DS flashcarts... looks like they'll be fine. They're not after DS. Just 3DS.
As for Sky3DS users... looks like things are gonna get a bit harder. Yes, it still works, yes, it could be worse. But right now Ban Hammers are your enemy. If you can't get private headers, good luck... Play without online. You can Streetpass, you can play over network, just no ONLINE/INTERNET play (looks at you Smash Bros. addicts).
If you have private headers from your dumped ROMs, edit your template and enjoy.
But if you're like me, hoping for a miracle, yeah.... no. Just gonna sit on 9.5-22u until they find another way to pokeinject.
REMEMBER:
power off 3ds
hold LT+RT+A+d-pad UP and turn on 3DS
it will boot into update screen
HIT CANCEL
it will power off
power back on, system update prompt should go away
Sit on your Gateway until 9.6 patch comes out (prolly by this weekend or next).
