Available right now is new software for the Wii. System Menu 4.0 contains a slightly revamped UI, but also ads support for up to 32GB SD cards.
What are you waiting for.. go update your Wii !
So perhaps my excitement at this announcement was a little overzealous, likely due to the fact I struggle for reasons to even turn on my Wii these days. Turns out there’s no real changes other than the SD card icon / support.
