I have a N3DS with firmware 8.1.0-0J and a Sky3DS with CN(J). I probably want to upgrade to 9.2. Able to play cia and region free. Possibly a custom firmware that is English? What are my options? I took a look at the threads below but I wanna be sure on the exact steps I need to take. https://gbatemp.net/threads/guide-upgrading-8-1-0-0j-to-9-2-0-20j.384960/ https://gbatemp.net/threads/guide-upgrading-8-1-0-0j-to-9-2-0-20j.384960/page-6#post-5420331 Do I need NTR CFW 2.0 or should I use 3.0?
