1. Introduction XP3 (also known as Kirikiri or TJS2 ) is a proprietary archive format primarily used by the Kirikiri/Z visual novel engine. Many Japanese visual novels and indie games pack their assets (scripts, images, audio, etc.) into .xp3 files. An XP3 Unpacker is a tool designed to extract the contents of these archives for purposes such as translation, modding, asset extraction, or game analysis.
