Ruffle
Ruffle is a Flash/Shockwave player built with WebAssembly and bundled with the full container image.
Ruffle needs the right platform folder
Ruffle only plays games from platform folders named flash or browser. If your Flash games are elsewhere, either rename the folder or add a platform binding in config.yml.
No controller mapping, so gamepad-only users will struggle with most Flash titles.
Supported games
Most 2D Flash games work, but 3D Shockwave and some advanced ActionScript titles may have rendering glitches (see Ruffle compatibility for per-title status).
Metadata
If you enable the Flashpoint provider, Ruffle games pick up descriptions, cover art, and tags from the Flashpoint database.
