The RetroArch Web Player is RetroArch compiled through Emscripten. The following outlines how to compile RetroArch using Emscripten, and running it in your browser.
Compiling
To compile RetroArch with Emscripten, you'll first have to download and install the Emscripten SDK. Once it's loaded in your shell, you'll run something like the following...
mkdir ~/retroarch
cd ~/retroarch
git clone https://github.com/libretro/libretro-fceumm.git
cd libretro-fceumm
emmake make -f Makefile.libretro platform=emscripten
git clone https://github.com/libretro/RetroArch.git ~/retroarch/RetroArch
cp ~/retroarch/libretro-fceumm/fceumm_libretro_emscripten.bc ~/retroarch/RetroArch/dist-scripts/fceumm_libretro_emscripten.bc
cd ~/retroarch/RetroArch/dist-scripts
emmake ./dist-cores.sh emscripten
Usage
Most of the magic happens on the browser so nothing really on that regard
I you want a self hosted version you need
- A web server, nginx/apache will do, download a build here: https://buildbot.libretro.com/nightly/emscripten/
- Extract the build somewhere in your web-server
- Unzip it in the same dir you extracted the rest, inside **/assets/frontend/bundle**
- Create an assets/cores dir, you can put game data in that dir so it's available under downloads
- chmod +x the indexer script
- run the indexer script (you need coffeescript) like this:
cd ${ROOT_WWW_PATH}/assets/frontend/bundle
../../../indexer > .index-xhr
cd ${ROOT_WWW_PATH}/assets/cores
../../indexer > .index-xhr
That should be it, you can add more cores to the list by editing index.html
