Starward is a third-party Windows desktop companion and launcher for HoYoverse games (Genshin Impact, Honkai: Star Rail, Honkai Impact 3rd, Zenless Zone Zero). It replaces the official HoYoPlay with enhanced features: game installation and update management (including pre-download and delta patching), gacha (wish) history tracking with UIGF import/export, real-time game record display (Spiral Abyss, Simulated Universe, etc.), HDR screenshot capture and batch conversion, playtime statistics, game account switching, and cloud game launching. The application is built with .NET 10 (C#), WinUI 3, and MVVM (CommunityToolkit.Mvvm), with a separate gRPC-based background service (Starward.RPC) for privileged game installation tasks. It uses SQLite via Dapper for local data storage, WebView2 for miHoYo login and game notices, and integrates with miHoYo/HoYoverse APIs via reverse-engineered clients. The codebase is well-structured into Core, RPC, Setup, and UI projects, with strong localization support (10+ languages via Crowdin). It demonstrates advanced Windows development skills including Win32 interop, Win2D image processing, and custom XAML controls. However, it is Windows-only, tightly coupled to miHoYo's volatile APIs, and contains some code duplication (e.g., DriveHelper) and hardcoded registry paths.
HSR-Scanner is a desktop application that automates the extraction of game data from Honkai: Star Rail using computer vision techniques. It simulates keyboard and mouse inputs to navigate the game's inventory system, captures screenshots of items, and uses OCR (Optical Character Recognition) to extract item statistics. The extracted data is exported to JSON format compatible with third-party optimizers. The application features a PyQt6-based GUI with configurable scan options, hotkeys, and performance tuning parameters.
