After a restless hour, there's no luck in finding Adobe's archived flash player versions. About a year or so, there used to be ALL versions of Adobe flash on this page: https://helpx.adobe.com/flash-player/kb/archived-flash-player-versions.html
...but they are all gone now. Seeing as how next-paging on google around 8 times doesn't seem to find any older downloads, I'm convinced the old versions of flash are gone forever, as I need them to run older flash games on ninja kiwi. Even if it was just one re-upload of flash player before 2018, this would be all that I need.
Correct, as is stated at the top of https://helpx.adobe.com/flash-player/kb/archived-flash-player-versions.html page, old versions of Flash Player have been removed due to Flash Player's upcomding end-of-life.
Its an archived version of the download page. It's what I used to download an old version, from 2013 in fact. Hope this helps!
Thanks so much! The web archive worked; this had been the only thing I hadn't tried. 😉
