Before the war in Iraq I seem to remember seeing a Flash (or similar) animation that shows the potential consequences of an invasion. It showed a map and went through a chain reaction of more and more countries being involved, possibly ending with nukes.
Does anyone else remember this animation? Does it still exist?
It did. But there are projects that work around this. The one in the link in @Smapti’s post uses Ruffle, an open source JavaScript implementation of Flash. It’s not perfectly compatible, but it’s being updated all the time. It works quite well for older Flash stuff.
Going the opposite direction, you can download either versions that the kill switch removed, or possibly just versions that never had the killswitch. These are not hosted by Adobe and you use them at your own risk.
Finally, there’s Flashpoint, which is an attempt to archive and preserve flash games. You download this huge archive of the games, and run them entirely locally.
