Version: 26.0.0
Sorry Mikael-B but I have a project dating back to 2004 that contains 2500 .swf files with a lot of ActionScript, about thousands of animations and videos, representing roughly 20 people per year of development. With the demise of Flash, I was forced to take my project off the web and there is no chance I will ever get a budget to redevelop it. I recently discovered Ruffle and JPEXS Free Flash Decompiler. Two weeks of work were enough to get a web version that's 90% functional... I'm still working on the remaining 10%. So, YES, Ruffle and JPEXS are invaluable tools and I'm delighted they're still available.

I wonder when you'd need this in 2022? I'm sure that in some places Flash is still a thing. I would have liked it in 2008.
