Pokemon X Update 15 Cia: Better

I see you're looking for information related to a Pokémon X update, specifically version 1.5, and possibly in a CIA (CTR Importable Archive) format, which is often associated with Nintendo 3DS game files. However, I'm a bit unclear on what you're asking for since the terminology might be mixed up or refer to something very specific within the Pokémon X game that I'm not directly aware of.
