If you have Flash Player, and it isn't playing properly, get Flash Player 6 here. Unzip with 7-zip. If you're using a Chrome version under 89, have an old version of Flash Player that supports it, and nothing is playing, then you'll have to update your Chrome version and get Ruffle.
Otherwise, if none of these things apply to you, and you're using a newer version of any browser, click here.
