Nope. That is correct. But there is technically no reason to update. Even with a dns block, you can play online. Only thing which doesn't work, is the eshop. This requires the nnu patcher beforehand.
Well, technically I need to update the system software to allow these games to start, or am I mistaken?
Btw: This concept seems strange to me. My friend played these games on this system. So the Fw can’t be too old for theses games? What exactly is triggering this update requirement? Even before I entered my wifi data I was getting these. I am a bit confused.
