clonezilla-util is a Windows CLI tool for inspecting, extracting, and mounting Clonezilla disk images and partition images without fully decompressing them to disk. It supports a wide range of compression formats (gzip, bzip2, xz, zstd, LZ4, lzip) and handles partclone metadata, LUKS encryption, raw drive images, and BitLocker volumes. The tool provides four main verbs: `list` (show file listings), `extract` (glob-based file extraction), `mount-as-files` (serve files via Dokan virtual filesystem), and `mount-as-image-files` (expose partitions as VHD/VHDX images). It is built on .NET 10 with extensive native interop via a C++ shim over the 7-Zip SDK, a custom seekable decompression layer, and a memory-aware cache governor that manages decoded spans in native memory. The codebase is heavily focused on performance—indexed random access, single-flight caching, sparse-aware I/O, and concurrent worker pools are central design patterns. It is accompanied by an enormous test suite (including a 40-hour golden-reference quartet) and thorough performance documentation.
SpecialK is a Windows DLL injection payload that enhances and fixes PC games. It intercepts graphics APIs (D3D8/9/11/12, Vulkan, OpenGL, DXGI), input (XInput, HID), system calls, and storefront overlays (Steam, Epic, GOG Galaxy) to provide performance monitoring overlays, HDR tone mapping, DLSS/NVIDIA NGX support, ReShade integration, hardware monitoring, and game-specific compatibility patches. The monolithic architecture relies on a MinHook-based hooking engine, ImGui for its control panel, and PresentMon for ETW-based frame timing analysis. It is actively maintained with recent commits and CI/CD, but carries a large vendored dependency footprint (Boost, GLM, LZMA, etc.) and includes some game-specific fragile hacks. Among the most reusable components are a thread-safe lazy global singleton (`SK_LazyGlobal`), a robust INI parser with encoding and change detection, and a command variable system with range and listener support.
