UnleashedRecomp is a PC port of *Sonic Unleashed* (Xbox 360) achieved through static recompilation. It replaces the original console's kernel, GPU, audio, and input APIs with native implementations, then applies a large set of behavioral patches to the recompiled game code for modern PC features like high resolutions, high frame rates, ultrawide support, and configurable controls. The application includes a full installer that extracts and validates game files from an ISO or directory dump, a custom achievement system, mod loading compatible with existing mod managers, and an ImGui-based UI for settings, achievements, and the installation wizard. The architecture is monolithic but modular: the kernel layer (memory, threading, file I/O) is separated from the GPU backend (with dedicated render thread), audio system, input handling, and OS abstraction for Windows, Linux, and macOS. The project relies on proprietary recompiled code (UnleashedRecompLib) and the original game assets, which are not distributed. The codebase demonstrates high engineering craftsmanship in areas such as deterministic memory allocation, virtual file systems, configuration templates, and cross-platform build orchestration, though it contains hardcoded game-specific addresses and auto-generated data that limit extensibility to other titles.
macroquad is a Rust game engine and graphics library inspired by raylib, providing a simple, immediate-mode API for 2D and 3D rendering, audio, input handling, and UI. The codebase is structured as a monolithic core library with several subcrates (particles, tiled, profiler, physics-platformer, macroquad_macro) that add specialized functionality. The architecture centers on a single-threaded game loop orchestrated by the `#[macroquad::main]` proc macro, with drawing batched via an internal OpenGL abstraction (miniquad). Key data flows include texture and font loading, immediate-mode UI widget rendering, and an experimental scene/coroutine system for game logic. The library is cross-platform (Windows, Linux, macOS, Web, Android, iOS) and emphasizes minimal dependencies and ease of use. While the core is tightly coupled, several subcrates and subsystems are well-encapsulated and demonstrate high craftsmanship.
