I uploaded my old save files to my wiiu via ftp and although they load fine, when the game tries to save it errors out:mito_sad:. In fact, even the data management menu is unable to delete them:mito_laugh:. After aimlessly playing with lftp for a while, I think that I've found the cause. The filesystem that the wiiu uses appears to support troonix permissions. The save file that the wiiu creates gets mode 0660, but when I upload via ftp it gets mode 0644 which is missing the write permission for the group. (I am surprised that it would have troonix permissions honestly. I thought that the ftp server was just faking it:mito_laugh:. )However, this ftp server doesn't appear to implement chmod:mito_ugh:, so I cannot fix it that way. Another idea that I have is to check if programs that allow you to view the contents on a pee cee have a way to mount it and correct the permissions that way, but I doubt that they would have such a feature:mito_weary:. If that is not possible, I will have to look into setting up that devkitpro thing and making a homebrew soyware that fixes the permissions or implementing chmod in the ftp server. Thank you for reading my blog post.
