It's a damn shame that HTML5 implementations of Flash, like Shumway (https://en.wikipedia.org/wiki/Shumway_(software)) and Swiffy (https://en.wikipedia.org/wiki/Google_Swiffy) are no longer being actively developed. I would have thought running SWFs in the JS sandbox would be a good way to get the compatibility of Flash, without the insane security bugs that it comes with.
And in case anyone is still in doubt about Flash's security woes - take a gander at the Flash CVE page at https://www.cvedetails.com/vulnerability-list/vendor_id-53/p.... There were FIVE CVSS 10 bugs (total and complete remote code execution with minimal user interaction, i.e. visit a malicious page and your computer is owned) published just two months ago. The author of Flashpoint is absolutely correct in his assessment that Flash will be overrun with security bugs as soon as it hits EOL in 2020.

And these days a WebAssembly build of Flash player would be an even better way, but it would depend on Adobe being willing to spend the time and the money to do it.
I’ve spent a ridiculous amount of time reverse engineering SWF files. There was even a time when Adobe published the SWF file bytecode format. It’s not a terribly complicated format like photoshop psd.
WebAssembly is probably a good target. However flash added a ton of apis in their latest versions. They were so ahead of the game before html5 before even became a thing.
I’m sure Adobe has patents/trademark on some of the things. Also Adobe Flex, that was a god send for rich internet applications. Their components were really well done and I still can’t fine equivalent things in this day and age.
I do strongly believe if Adobe had open sourced big chunks of things, Flash and a number of technologies would still be relevant today. Their big money makers were the IDE’s like Flash Studio, dreamweaver, photoshop etc. The formats and the runtimes should have been open from the get go.
Although it was the Ballmer era when most corporate CEOs truly believed OS was cancer.
Flash was mixed with licensed non-opensource-able stuff and it wasn't a trivial code base in the first place. Given that Adobe hasn't actually made much money off Flash, such an effort would have been likely unfeasible and prohibitively expensive.
Someone from the Flash team could chime in here to give more details.
On a sidenote, swf specification was simply great. It was only after I read it that I fully grokked the Flash development (not that I did much of it, because I wasn't a fan of Flash webpages, and couldn't find a way to make money off Flash games).

Excuse my ignorance: I never used Flash (I was already against abusing the browser for things like that so I only built desktop apps with Delphi etc) but I do use Haxe(with OpenFL) now; is that not supposed to implement those APIs?
Another option might be for them to open source the code and let others do the port. However, there might be legal barriers to doing that if they don't own the rights to it all.
The thing is, Flash is still in use, just not on the web and it's not called Flash. It's called Adobe Animate. Adobe Animate, formerly Flash, is still in use for animating shows on television. Open sourcing Flash would mean creating a potential competitor with Animate, which Adobe surely doesn't want. The only reason Adobe would have to open source Flash is "out of the kindness of their hearts" which is not enough. This is nothing but a needlessly risky business venture to them.
They wouldn’t need to open source the editor, only the player, so competing with Animate shouldn’t be an issue. But yes, there’s not much incentive to open source anything.
Yes, we're in a different situation than people who preserve old console or PC games because those have a platform that is pretty much known and extensively documented. Even if you can't run the hardware anymore there are emulators that work great. It's harder on closed platforms like Nintendo.
With Flash, I don't know that we'll ever have an open source desktop player to allow preserving these games and allowing them to play on all future platforms. You might as well ask someone to write a complete implementation of Java, with no access to the source code, for free. Eventually we'll probably be stuck with old virtualized editions of windows running old versions of Flash. Let alone the possibility of leaving x86 behind completely.
