I can play Flash files right now and you likely could too.

There are Flash Players aka SWF Players out there for playing saved .swf files. Mine works perfectly. Find one that works for you.

I can also play things that needed flash player online. So far ive only tested Chrome and Fire Fox with SuperNova SWF Enabler. Its buggy on Fire Fox but all progress takes time.

Lots of people are doing what they can to make what once relied on Flash safer and more accessable to everyone. Pretty much playing flash files like they were webassembly files or html5 file.

I suggest telling site you like about such things. Some projects I know of other than SuperNova SWF Enabler are Ruffle.rs, Waflash, Apache Royale, and CheerpX.

Therre is also a browser made for flash past 2020 called Puffin.
