BeatSaber-IPA-Reloaded is a mod loader for the Unity game Beat Saber. It injects into the game process via a native DLL proxy (Doorstop) that hooks winhttp.dll during Unity's startup to load a managed injector assembly. The injector bootstraps the loader, which discovers and manages plugins, handles dependency resolution, configuration, logging, and anti-malware scanning. The repository comprises several assembly projects: a native proxy (C++), a managed injector (C#), the loader itself, a command-line patcher/installer, and a meta-project that assembles the final output. The loader features an advanced configuration system that uses System.Reflection.Emit to dynamically generate type-safe config stores with automatic serialization, change tracking, and thread-safe locking. Plugin dependencies are resolved via topological sorting with cycle detection and conflict handling. The logging subsystem supports pluggable printers for console, file, and compressed output. The code demonstrates high craftsmanship in IL emit code generation, dependency graph algorithms, and fast reflection accessors. However, some parts show age (deprecated thread abort calls, obsolete plugin interfaces) and tight coupling between assemblies via InternalsVisibleTo attributes. Overall, it is a solid mod loader with several reusable components.
