Ruffle: Adobe Flash Player Emulator

Ruffle is an Adobe Flash Player emulator that allows Flash content and games to run in modern web browsers without additional plugins. It uses WebAssembly and JavaScript to emulate Flash at the bytecode level.

What is Ruffle?

Ruffle is an open-source Adobe Flash Player emulator designed to preserve Flash content and games after Flash reaches end-of-life in 2020. It allows SWF files and Flash content to run in modern web browsers without requiring any additional plugins.

Ruffle works by emulating Flash at the bytecode level using WebAssembly and JavaScript. It dynamically translates ActionScript and Flash bytecode to JavaScript just-in-time, allowing the content to run at near-native speeds. This gives web browsers the ability to natively run Flash content without security issues or reliance on third-party plugins.

Some key features and capabilities of Ruffle include:

  • Runs natively in all modern web browsers using WebAssembly
  • Preserves Flash games, animations, applications, and multimedia content
  • Implement support for ActionScript 1, 2, and 3
  • Recreates Flash APIs like display list, filters, networking, audio, etc
  • Open source project focused on long-term preservation
  • Allows old Shockwave Flash (.swf) files to run without changes

Ruffle aims to serve as a replacement for the discontinued Adobe Flash plugin, ensuring Flash content remains available and playable for future generations. Its focus is on stability, compatibility, and preservation rather than new feature development.
