## Description

Ruffle is an Adobe Flash Player emulator built to execute legacy animation and interactive content within modern web browsers and desktop environments. By utilizing a high-performance WebAssembly engine, it interprets legacy bytecode and scripting languages to render content without requiring original plugins or outdated software. The project functions as a cross-platform media player that preserves access to archived digital assets by simulating the original runtime environment.

The emulator distinguishes itself through its ability to automatically detect and replace obsolete media objects on websites, restoring functionality without manual code changes. It provides a comprehensive suite of tools for managing playback, including hardware-accelerated rendering for vector and bitmap graphics, custom shader processing, and event-driven input translation that maps modern pointer and keyboard interactions to legacy system events.

Beyond core playback, the project includes capabilities for parsing and manipulating legacy file formats, managing audio stream decoding and mixing, and providing a JavaScript API for dynamic integration into web applications. It also supports cross-origin resource sharing and network socket proxying to maintain security while enabling content to function in contemporary environments.

The project is implemented in Rust to ensure memory-safe execution of untrusted legacy binary files. It includes automated testing suites and benchmarking tools to evaluate compatibility and performance across large collections of legacy media.
