help with miitopia files

hey!! so with the help of Supurreme, i've gotten most of the files for miitopia!
i'm finding everything okay except for the mii faces themselves. does anyone know where i could find them in the files? do they do something weird like source the mii maker or does miitopia have the faces and meshes themselves? 

also, i'd like to upload one or two of the job costumes, but i don't have the time (or desire) to format them all correctly for one job. how would i go about uploading one of the job outfits? would i make a new category for each job??
