As you may know from December 31st 2020 Adobe official support for Flash is over.

BlueMaxima’s Flashpoint is a webgame preservation project.

Since early 2018, Flashpoint has saved more than 70,000 games and 8,000 animations running on 20 different platforms. Flashpoint was started in January 2018 by BlueMaxima in an attempt to outrun the disappearance of content prior to the death of Flash. It has since evolved into an international project involving over 100 community contributors, encompassing both webgames and animations created for numerous internet plugins, frameworks, and standards.

Flashpoint utilizes a strong selection of open-source software. By combining the power of Apache, a custom-built launcher, and their own application called the Flashpoint Secure Player, we can play web-based media in a quick, user-friendly environment without leaving permanent changes or security holes on your computer.
They offer two versions of the software; Ultimate, which contains every piece of media in an offline ready format, and Infinity, a smaller distribution that allows you to download and play content at will. Both versions are unaffected by the end of support for Flash and other plugins.
This project is and will always be entirely non-profit.
