Downloading a pre-patched CIA from random websites supports piracy, which hurts the developers we love. We encourage all readers to support Square Enix by purchasing the official Dragon Quest XI releases available on PS4, PC, Switch, and Xbox One.
CIA stands for CTR Import Archive. It is the file format used to install games, updates, and DLC directly onto a modded Nintendo 3DS console's custom firmware (like Luma3DS).
This is where the search phrase becomes critical. You don’t want a buggy beta or a machine-translated mess. You want the final, polished release.
Believe it or not, the 3DS version actually features voice acting (though compressed for the handheld). The UI utilizes the dual screens perfectly, offering a map on the bottom screen and a streamlined battle interface.
