Ruffle is an Adobe Flash Player emulator written in the Rust programming language. Ruffle targets both the desktop and the web using WebAssembly.
Ruffle is in the proof-of-concept stage and can currently run early Flash animations and games. Basic ActionScript 1.0/2.0 support is in place and improving; ActionScript 3.0 support is forthcoming. For more info, read the project roadmap.
Nightly builds of Ruffle are available for desktop and web platforms including the browser extension.
Windows desktop builds require the x64 2015-2019 Visual C++ Redistributable.
Follow the official guide to install Rust for your platform.
cargo run --package=ruffle_desktop -- test.swf
Follow the instructions in the web directory for building either the web or browser extension version of Ruffle.
If you have a collection of "real world" SWFs to test against, the scanner may be used to benchmark ruffle's parsing capabilities. Provided with a folder and an output filename, it will attempt to read all of the flash files and report on the success of such a task.
cargo run --package=ruffle_scanner -- folder/with/swfs/ results.csv
If you have a swf and would like to capture an image of it, you may use the exporter tool. This currently requires hardware acceleration, but can be run headless (with no window).
