First, I remember that "Pokémon Ultra Moon" is a version of the seventh generation Pokémon games, released in 2017 for the Nintendo 3DS. The 1.2.cia file likely refers to a specific version of the game's update or patch. But I need to confirm the actual version numbers. Wait, Pokémon Ultra Sun and Ultra Moon had several updates. The 1.2 version was probably a major patch that might have included bug fixes, balance changes, and maybe new features like the Festival Plaza or changes to the Alola region's events.
