What is the Emergency anyway?

Flash today is a fallen titan, once used to make games, animations and all kinds of interactive web content.
While no one uses Flash nowadays, there are still a lot of things that were made with Flash, scattered across the vast internet. All it takes is a Flash Player plugin to run these.

Unfortunately, Adobe has decided to end support for Flash Player. Modern versions of Flash Player will cease to function on 31 December of this year, and Adobe will also be removing any and all downloads for past versions on their website. As a result, thousands of websites across the internet, spanning decades are going to be blocked off.

What is the Flash Player Emergency Kit?

Believe it or not, there are a multiple independent efforts to circumvent the damage brought on by the end of Flash Player. There are preservationists, working to copy these games over into alternative formats. There are emulators, which can simulate Flash Player. And there are archives of Flash games and animations, which people have previously salvaged. If that’s too much to handle, you can just follow updates from these different projects, here on Data Horde.

This page serves as a list of resources, for anyone interested in the preservation of Flash media or anyone who just wants to learn how they can access a certain website post-31 December.

We’re currently conducting a Flash Player Usage Survey to see how dependent internet users are on Flash Player, even in its final days.
