No modern Pokémon game is complete at launch. Pokémon Violet received numerous (often labeled v1.1.0, v1.2.0, v1.3.0, up to v3.0.1). These updates are distributed as separate NSP files that install over the base game. They address performance issues, bug fixes, and—most importantly—enable compatibility with the DLC.
