They do have Ruffle on their site (a bit slower to load IME, but functional) even for new (non-raster) animations. Although I do believe that’s just reverse chronological order of individual animations so not exactly the original experience.

There are the orginal .SWFs for that, disjointed in their own way. I wish they (or someone) would’ve merged things so the old menus actually worked, if not further like each file being a season.
