Summary
OpenKH is a free project that brings together Kingdom Hearts technical documentation, tools, code libraries, and a foundation for modding the commercial games. Its documentation spans multiple games and remasters, shared assets, tools, and the OpenKH Game Engine. The Mod Manager installs and manages mods for supported PC ports and PS2 versions of several titles; users can add mods from GitHub repositories or archive files and group assets into collections. Panacea lets users toggle mods without directly overwriting original game files. The guide names Kingdom Hearts, Kingdom Hearts II, Re:Chain of Memories, Birth by Sleep, and Dream Drop Distance as legacy-class games, and describes support for PC releases from Epic Games Store and Steam. An Image Viewer handles common image formats and Kingdom Hearts formats including IMD, IMZ, and Birth by Sleep font ARC files, but image import functions remain in development. The engine aims to recreate Kingdom Hearts I through Dream Drop Distance and currently offers basic Kingdom Hearts II support on Windows, Linux, and macOS, including Raspberry Pi. Tools require the .NET 8.0 Runtime. The engine requires the user’s original Kingdom Hearts II PlayStation 2 or PlayStation 4 copy; OpenKH does not host copyrighted original game files.
Who it is for
OpenKH suits Kingdom Hearts fans interested in technical documentation, mod management, or working with game assets. Users should be prepared to provide required original game files and install the .NET 8.0 Runtime.
