    Cuberite

    Cuberite

    A lightweight, fast and extensible game server for Minecraft

    Cuberite is a lightweight, open-source Minecraft-compatible multiplayer server implementation written primarily in C++. The project was created as an alternative to the official Java-based server software with the goal of improving performance, efficiency, and flexibility. By using C++ instead of Java, Cuberite reduces memory consumption and CPU overhead while still allowing players using the standard Minecraft Java Edition client to connect and play. The software recreates core gameplay systems such as world generation, multiplayer networking, and commands while allowing extensive customization through a plugin system. One of its defining features is a Lua-based plugin API that allows developers to easily extend the server with custom features, commands, and gameplay mechanics. Cuberite is designed to run on a wide variety of platforms including Windows, Linux, macOS, Android devices, and embedded systems.

    XenosRecomp

    XenosRecomp

    A tool for converting Xbox 360 shaders to HLSL

    XenosRecomp is a specialized project within the Hedge-dev ecosystem that focuses on recompiling and reconstructing the Xenos GPU pipeline used in the Xbox 360, enabling accurate rendering when porting games to modern platforms. It works alongside CPU recompilation tools by translating GPU-specific instructions and behaviors into equivalents that can be executed on modern graphics APIs such as DirectX or Vulkan. This allows recompiled games to maintain visual fidelity while benefiting from modern hardware acceleration. The project addresses one of the most complex aspects of console reverse engineering, which is accurately reproducing proprietary GPU behavior in a portable and efficient way. By reconstructing the graphics pipeline, XenosRecomp enables developers to render scenes correctly without relying on emulation layers that can introduce performance overhead or inaccuracies.
