The gateway to installation on a hacked 3DS is almost always an app called FBI. Not the federal agency, but the open-source installer developed by Steveice10. Its icon, a nondescript blue badge, sat on the home menu.

Nintendo 3DS games are normally region-locked. A Japanese console cannot play a North American cartridge without modification.

The official Pokémon Ultra Moon cartridge sold in the Americas, Europe, and Australia is technically the “US” or “EUR” version, but both contain the same WORLD localization data—meaning English, Spanish, French, German, Italian, Japanese, Korean, and Chinese are all present.

In the context of update files, “WORLD” indicates that Update 1.2 works with any legitimate copy of Ultra Moon, regardless of its original region (USA, EUR, JPN), provided the base game CIA or cartridge matches the same title ID family. This is important for collectors using multiple region consoles.
