1) Got CFW? If not, follow this:
3ds.guide
2) Got FBI, or any other ".cia" installing application? If so, install this:
freeShop
3) Find a site for sharing and distributing eShop "title keys", and press a button like this:
View attachment 89774
Get the QR that appears and scan it in the QR mode of the"enctitlekeys url" option in freeShop's own options menus.
4) Save the URL, reboot freeShop and install your favorite eShop games with ease.
GBAtemp.net does not condone piracy.
Finding a site suitable for sharing title keys is simple - just ask Google for a 3DS title key website.
For games not in the title key database or the eShop, you will have to look elsewhere.
We can not help you find a title key site, or any other ROM downloading sites, and it is not permitted in the site's rules to share ROM site names or links.
