Ruffle

Ruffle: Flash Player emulator to help preserve useful web Flash content.

Ruffle Nightly is an open-source Flash Player emulator that is coded in Rust by a very passionate developer community.

The purpose of the program is to help developers preserve useful web Flash content and even make it accessible to users that can’t run the official Flash Player.

It will be able to run natively on all major OSes (e.g. Windows, macOS, and Linux, Android, iOS devices, and pretty much all modern web browsers).

A great thing about Ruffle is that it's very flexible, which means you can install it and able to run it as a standalone app.

All in all, Ruffle Nightly is a great Flash Player emulator that is designed to help developers preserve useful Web Flash content, and make it accessible to users that cant officially run it anymore.
