Half true. Emscripten implements (much of) the SDL 1.2 (and also SDL_mixer 1.2) API in Javascript here: https://github.com/emscripten-core/emscripten/blob/main/src/library_sdl.js https://github.com/emscripten-core/emscripten/blob/main/src/.... On the other hand SDL 2 (and SDL_mixer 2) are proper ports (which you linked to). So there's quite a size penalty to using SDL 2 rather than SDL 1.2, but the reimplemented SDL[_mixer] 1.2 is incomplete and differs from official.
