Ruffle is a cross-platform Adobe Flash Player emulator designed to enable playback of legacy SWF content in modern environments. Built using Rust, Ruffle provides a robust alternative for accessing Flash-based media, games, and applications that were previously reliant on Adobe's proprietary Flash Player.
Key Features:
Supports ActionScript 1, 2, and 3 for compatibility with a wide range of Flash content.
Runs natively on desktop platforms and via WebAssembly in web browsers.
Can be installed easily using winget for seamless integration into your workflow.
Offers a demo page for testing SWF files directly in the browser.
Audience & Benefit:
Ideal for developers, archivists, and users of legacy Flash content who need to preserve or access interactive media that would otherwise become inaccessible. Ruffle empowers individuals to continue engaging with historical digital experiences while leveraging modern programming languages and security practices.
Follow the instructions in the ruffle-android project for building the Android application of Ruffle.
Scanner
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 --release --package=ruffle_scanner -- scan folder/with/swfs/ results.csv
Exporter
If you have a SWF file 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).
cargo run --release --package=exporter -- path/to/file.swf
cargo run --release --package=exporter -- path/to/file.swf path/to/screenshots --frames 5
