All Sims (and pets!) come in .sim format so put in your SavedSims folder. I'm a terrible person and forgot to list CC T_T I can try to direct you if you ask, but I can't make any promises as I made these sims before I got sick at the beginning of January and I'm Absent-Minded at the best of times... They come packaged in EA clothing and the shaved basegame hairstyle so they shouldn't cause any problems. Miranda and Hikaru have custom skins, from GoS and Lemonleaf A2.0 respectively, so if you don't have those in your game they'll have the black shadowed skin. Don't be alarmed if this happens, though, just switch them to a different skin (it will appear odd in CAS but will be fine in-game).
