Please bare with me! I have a Hardware Modded Wii, However I also have homebrew channel and usb loaders installed via the twilight hack) Im currently running Vers 3.2u of the system menu. I would like to upgrade my Wii to a more recent but 100% compatibility firmware. 4.0? or 4.1? since 4.1 is now live on the Wii channel is it safe to use that or will I lose some functions? I honestly only use the USB loaders anymore, im not watching DVD's and such just backing up my games onto the USB loaders. Also i currently have IOS Version 249 (rev10) installed for USB loaders (Coverflow) is there a need to update this as well? Thanks in advance guys and gals!
