Shumway was a great project and it's definitely unfortunate that it was abandoned. I completely agree with you that keeping old content available is important.

Shumway was a great project and it's definitely unfortunate that it was abandoned. I completely agree with you that keeping old content available is important. Using the DOM was definitely the right choice. Over the last few weeks I started to split Shumway into smaller packages so it's easier to work on it. For the moment I have a typed AST, a parser and a render for shapes with solid fills, they are all written both in Rust and Typescript (updated to the latest version). The biggest challenge remains the documentation and VM but Adobe open-sourced the FlexSDK and AVMPlus so you can find lot of information in the source code. I still don't know if I'll try to update the Shumway VM or write Rust bindings for AVMPlus and try to compile it to something like Wasm. Basically, for the moment it's at the very beginning so I don't know if it will even be useful, but I am determined to work on it and if it fail I could then help for some other projects such as Lightspark (which still seems somewhat maintained even if the activity dropped). Say what you want but losing Flash is losing a great part of the history of the internet, for all its problems it's worth preserving.
