I suppose this should be possible, by replacing the file tree that contains the Jocly 'library' by the corresponding file tree from my website (which supports the new games), and making a separate html page for each game, which embeds Jocly with parameters that request that game. I don't know if the version of Jocly installed here now is the standard version from GitHub, (from which I started), or that there are some additions (like extra games) we don't want to lose. In the latter case things would be a bit more complex, as we would somehow have to merge the additions.
