I found my old wii and it has 4.3U so I want to homebrew it but I don't have a sd card. What I wanted to do is to just use flashhax but I don't even have the internet browser so I would have to update the system to open wii shop to download the internet browser (I KNOW ITS DOWN BUT IT MIGHT WORK IF I JUST WANT TO DOWNLOAD THE BROWSER) The point is is it safe for me to update my wii to the latest version or should I just wait to buy an sd card
