Technology Stack:
OpenEmu is built using macOS frameworks and libraries. The project utilizes various programming languages and technologies, including:
- Objective-C and Swift: The core components of OpenEmu are written in Objective-C and Swift, taking advantage of the native capabilities of macOS.
- SDL and OpenGL: OpenEmu relies on the Simple DirectMedia Layer (SDL) library for handling input, audio, and video, while OpenGL is used for rendering graphics.
- Core Emulation Cores: OpenEmu incorporates emulation cores from various open-source projects, such as Nestopia, Genesis Plus GX, and Gambatte, to emulate different gaming consoles.
- WebKit: OpenEmu utilizes WebKit for the in-app browser used to download and install game cores.
These technologies were chosen for their compatibility with macOS and their ability to provide a smooth gaming experience for users.
Project Structure and Architecture:
OpenEmu follows a modular architecture, with different components responsible for various functionalities. The project includes the following main components:
- Core: The core component handles the emulator engine and gamepad input, providing the foundation for running different console emulators.
- Library: The library component manages the organization, metadata, and cover art for the game collection, allowing users to easily browse and launch games.
- User Interface: The user interface component presents the unified interface to users, providing access to the library, settings, and game-specific features.
