The official Homestuck site will still let the original SWF files load as long as you have something that can play them. Ruffle works fine. You can also use one of the few browsers that still supports PPAPI plugins (like Falkon) with the official Flash plugin.
But personally I’d say to just use The Unofficial Homestuck Collection, which is more pleasant to read through than the original ever was.
