@blanco! My methods included transferring from Switch to Amiibo to 3DS (as a file) and then transferring that file to my PC over FTP, and also using InfiniMii to transfer Miis from it (or Mii Creator) to my Wii Remote and onto a Wii (while also using the save editor you mentioned to make it editable if necessary). Again, vice versa for each method.
