These archives are the lifeblood of the Kirikiri (TVisual) engine—a popular visual novel engine used in thousands of games, including titles from NekoNyan, Frontwing, and countless doujin (indie) circles.

Title: Reverse Engineering the XP3 Archive: Design and Implementation of an Unpacker for the Kirikiri Engine

Abstract:
The XP3 archive format (also known as Kirikiri archive) is a proprietary packaging system used primarily by the Kirikiri (TVisual) visual novel engine. This paper analyzes the structure, encryption methods (specifically XTEA), and compression (zlib) used in XP3 files. We present the design and implementation of an "XP3 unpacker"—a tool for extracting contents from encrypted and compressed XP3 archives for legitimate purposes such as data recovery, localization, and security analysis. The paper also discusses the legal and ethical boundaries of reverse engineering such formats.
