in summary i have installer and only put in FBI folder and remove old CIA ¿how create copy of my savedatas? in case for mistakedo you have FBI or another CIA Installer? Just put the freeshop cia on your sd card, and install it using a cia installer. That's it!
If you want the freeshop cia to auto update its keys, just scan the qr code at that title key site, in freeshop.
