Wii with D2E A9 chip installed. Is it safe to upgrade to 4.2?
I just acquired a Wii with a D2E A9 chip on it. It is a virgin Wii, no HBC or any other thing installed. It is currently loaded with firmware 4.1. So, my question is, is it safe to upgrade to 4.2 (via game update or Wii internet connection)? Can I? Or I'd better not upgrade?
I'm just concerned with the fact that I will or not will be able to play backup games in the future (or even new games like NSMBW).
Thank you in advance.
