I've a JPN Wii with Wiikey installed. I plan to change the region from JPN to US by using Any region changer. My question is 1. After changing system and region to US, will I still need to patch game with WBB or Regionfrii? (If I don't change game setting) 2. (If I change game setting) I only need a Wiikey config disc and change Wiikey region setting as well, right? I hope I don't have to open my Wii. 3. Will I be able to run US Wiiware or VC? 4. If I wanted to update my Wii firmware which firmware do I need 3.X J or 3.X U? Thanks much.
