I recently bought a used Wii from a relative of mine. Apparently, it can play games from DVD backups so it must be softmodded or so. But the short time I was able to try it on my relative's house I wasn't able to see anything different than normal (apart from there being two news and weather channels) Wii menu. Would it be safe for me to update the system to the latest version? I think the version on it is 4.2E. Thanks in advance.
