It is Flash files at least (https://flashmuseum.s3.amazonaws.com/htf_ep_45_out_on_a_limb... as an example)

Seems to be using the Flash Player emulator Ruffle - https://ruffle.rs/

> On our website, Flash content will run on your browser using the Flash Player emulator ruffle. Ruffle is an open source emulator built using the Rust programming language. It uses WebAssembly to run Flash content on modern browsers

Amazing. Is this related to efforts by archive.org to get all of their archived stuff working? (Believe they also are using Ruffle)

They've reverse-engineered flash and written a player compatible with modern browsers. Crazy amount of effort, but worth it.

That’s really impressive. And good to see. I assumed all this flash content was just lost. Surely there are lots of bugs or unsupported features but hopefully it continues to be developed.

I suppose another option is to just use a browser tgat does support flash? Seems like some exist.

Ruffle isn't a reverse engineered project, from what I can tell. it seems like they're following some spec, and comparing with the flash player, not decomping it

I contributed to Ruffle. They don't reverse engineer (this is explicitly a no), the knowledge comes from the (poor) documentation and from the open sourced flash virtual machine.

it looks all the files are unmodified, no nothing seems ported they're probably using a ruffle implementation
