I have no idea what the contents of the 7z file are supposed to be...
are they supposed to be the save files? where is the banner file?
The titleid/gameid does not exist in any form in any of the files in this archive.
how would dolphin have any idea what to do with this archive?
you seem to misunderstand the import wii save feature
it is for encrypted data.bin wii saves exported from a real wii or dolphin
it will not import whatever random archive you throw at it
if you want to manually manage the save by using 7zip, than you are responsible for the import
