I've bemoaned the death of Flash before, and the loss of so many classic games. Virtualization is a long-term solution some of the time, but many don't work right once their original sites are down.
Well, turns out some cool people actually built a proper solution to that:
http://bluemaxima.org/flashpoint/They not only archived "Eleven thousand games", but the program sets up proxy settings to let the games "fetch" resources they expect to find online. The resources are actually stored locally, of course. I got the a-la-carte option instead of all 76GB, and it works very well. A lot of games which are still around play significantly better, since it uses the more efficient stand-alone flash player.
The list includes some Java games like Realspace 2 which aren't available in the a-la-carte for whatever reason, but yeah! A friend pointed it out last night since we were talking Flash, and it's just really comforting to know that such an easily-accessible archive will exist. It's one thing for the games to be technically playable, this is actually convenient.
(Then to play Realspace 2, a java game, I had to use IE (Firefox and Chrome simply don't support the plugin system anymore), find an old site still hosting the game, then configure *Java* to add a security exception for the specific website. Then restart the browser of course. Then confirm that, yes, I wanted to run the Java app on the site I specifically whitelisted in a config tool. At some point they simply removed the option to prompt the user. I've worked with Java web threats so I sorta get it, but... It's kinda sad that normal users aren't trusted to decide.)
