Updated IOS9, IOS57, and IOS61 in J region (updated in 4.2rev04 for other regions) Updated manually from the "Wii System Update" choice in the Wii Options, or after testing a connection in the "Internet" setting. Such Wii System Updates mayI bought a Wii at the weekend which was v4.1 and followed the instructions to load HBC using Bannerbomb v1. All went well and the HBC was there. A Wii System Update will add new features to upgrade your Wii console. and manually select "Wii System Update" from the Wii System Settings page.
