In their own words
OpenKh
OpenKH brings together technical documentation, tools, code libraries, and modding support for the Kingdom Hearts series. Its documentation covers 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 games. Mods can come from GitHub repositories or archive files, and collections can group assets for multiple titles. Panacea lets users switch mods on and off without overwriting original game files. The guide lists Kingdom Hearts, Kingdom Hearts II, Re:Chain of Memories, Birth by Sleep, and Dream Drop Distance as legacy-class games, and says PC releases from Epic Games Store and Steam are supported. OpenKH also includes an Image Viewer for common and Kingdom Hearts-specific formats, including IMD, IMZ, and Birth by Sleep font ARC files; it exports images, while import functions are in development. The engine has 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 is free; the listed plan is free.
Source 2 Viewer
Source 2 Viewer is a free, open-source tool for browsing VPK archives and inspecting or exporting assets from Source 2 games. It can search, extract, and create archives, including VPK versions from Source 1. Its renderer displays maps, models, physics, and particles with real-time lighting and animation playback. The tool also inspects textures, audio, shaders, and other Source 2 resources. Maps, models, physics, and animations can be exported to glTF 2.0, with material conversion and batch export; maps, models, and materials can be decompiled into editable formats for Hammer, ModelDoc, and Source 2 Workshop Tools. Texture tools cover channels, depth layers, mip levels, cubemaps, and HDR, with image export. Its audio player supports WAV, MP3, and Source 2 formats. The graphical interface is Windows-only, though the guide describes running it on Linux and macOS through Wine; the command-line utility is available for Windows, Linux, and macOS. The GUI is portable and requires no installation. Some data may be lost during export, and reverse-engineered format support is incomplete. The project is volunteer-built and says it is not affiliated with Valve.
