I forgot this was in the queue: [Wayback/Archive] ruffle-rs/ruffle: A Flash Player emulator written in Rust.
It is cool and plays a lot of Adobe Flash content and supports quite a bit of the underlying ActionScript language.
I really wish the web version could play web.archive.org/web/20160706140910oe_/http://games.erdener.org/laser/laser.swf (older), web.archive.org/web/20061211011310/http://www.gamuz.com/jeux/laser.swf (newer) or web.archive.org/web/20030827220214oe_/http://www.lurghi.net/laser/laser.swf (newest) but alas when running from https://ruffle.rs/demo/, that SWF is trying to download https://ruffle.rs/demo/config.txt some 20-30 times per second.
Maybe there is a workaround, as I have only tried the [Wayback/Archive] Ruffle Web Demo page (which is the easiest way to get started).
