Add 'AllowListUrlPattern= to mms.cfg (Difficult, may not work forever).Use a flash-enabled browser (Medium difficulty, less secure).
See below for some possible solutions (USE AT YOUR OWN RISK): There a few temporary workarounds for continuing to play Flash games in-browser, however these are not guaranteed to work forever. Currently only ActionScript 2.0 games are supported and functionality isn't perfect yet, but since writing this Super Smash Flash 1 is already mostly functional! If you'd like to support the development of Ruffle we urge you to check out its Open Collective page. However, thanks to a project called Ruffle significant strides are being made to emulate Flash. SSF2 development is still continuing regardless, however if you typically play SSF2 in the browser you will unfortunately have to switch to the downloadable version of SSF2 until a solution comes around.
Due to the Flash Player reaching end-of-life, it is no longer possible to play this game directly on this page the traditional way in most browsers.
