I've recently bought a modified Wii, which has Homebrew v4.1U. I connected it to the wifi and was asked if I wanted to update the wii since there is an update found but I clicked No. Is it safe to update the wii without affecting the Homebrew Channel and the USB loaders? I use the Configurable USB loader to play my downloaded games. If there is a place where I can update Homebrew without affecting anything (just an update to the files but nothing removed)? Also, I got Call of Duty: Black Ops but I can't play online multiplayer because apparently an update is needed in the Wii Shop. How to play games if an update is needed for them? Can I update them and still play the games modified?
