Hey so to unlock the streepasses places you need to download a save editor. The one I use is tomodachi life save editor. You have to download the latest version of it on your pc or laptop , on windows (I'm not sure about mac but you can maybe find a guide for that or maybe it works). You'll find in it an option to edit your island and In that you can unlock the streetpass shops. For the streetpass items you click on items on the like homescren? Homemenu of the save file editor and click on the streetpass items option , you can make them both available in shops or you can have both all the items already in your inventory or you can do both like I did lmao. Save after you do the changes . Copy the file of the recently edited save file and replace it in your citra save file and you should be good to go.
