It says the original post was last updated in 2017, have there been any developments or things learned in the last couple years that are important enough to add to it? I definitely agree with not messing around with things if you're not certain you know what you're doing, and unfortunately I'm a moron with this stuff plus I have no idea what advice is outdated or not, especially now that I'm guessing the Wii U is no longer online.

 

My vWii is saying "Your Wii System Memory is full" every time I load it, despite this not being the case. If go into data management, it will always say 0 blocks, even if I delete something. I can still install and uninstall WADs through modmii, so I know there is space for sure. Normally this wouldnt be an issue, but a WiiU app I want to use requires there be free vWii space.

Any ideas?
