The site I use: https://www.gamesloon.com/free-cartoon-26/samurai-jack-games-33/samura-jack-code-of-the-samurai-108.html#readmore

I'm sure it's hosted playable on other sites as well. In addition, all the other Samurai Jack flash games are hosted downloadable as .dcr file, but I don't really know how to run those. If anyone can manage to make one work, they can submit under "emulator" option.
