So, it's been awhile since I've used my Wii and right now it's running some firmware from like a year or so ago. Thing is now that I pretty much forgot what's installed and everything (All of the custom ISOs and whatnot), would it be okay just to upgrade it from the Wii and then hack that again? Will it screw up my Wii and will it reset the CISOs I installed? I'm assuming this will be the easiest way to get everything up to date. I don't mind if I have to reinstall my homebrew or anything. I have SSBB so I should be able to do it.
