Jazz Jackrabbit: 2 Open Source Clones Compared
openjazz.github.io is not an independent clone but a browser build of OpenJazz itself, compiled via Emscripten and packaged with the Jazz Jackrabbit Shareware 1.1, Holiday Hare, and Holiday Hare '95 data files so it can run directly in a browser. OpenJazz is the underlying cross-platform project, supporting a much wider range of targets — including 3DS, PSP, Switch, and Wii — beyond the web, and likewise needs data files from one of the original games to run.
