Emscripten build

[werwolf2303]

Is it possible that there will be an emscripten build at some point?

I'm also interested in this

It looks like there is an emscripten port of the libretro core

[patrickcorrigan]

Are there build instructions?

For compiling on Ubuntu, I downloaded snes9x source. Then ran these lines:

git clone https://github.com/libretro/RetroArch Retroarch --depth 1 --branch master

git clone https://github.com/emscripten-core/emsdk emsdk --depth 1
cd emsdk
./emsdk install latest
./emsdk activate latest
source ./emsdk_env.sh

cd ../snes9x/libretro

emmake make -f Makefile platform=emscripten
cp *.bc ../../Retroarch/dist-scripts

cd ../../Retroarch/dist-scripts
chmod a+x dist-cores.sh
emmake ./dist-cores.sh emscripten

And I got some files. Retroarch\pkg\emscripten\snes9x_libretro.wasm Retroarch\pkg\emscripten\snes9x_libretro.js

@kalita-kan Nice, just tried building there and I get

ports:INFO: retrieving port: zlib from https://github.com/madler/zlib/archive/v1.2.11.zip
make: *** [Makefile.emscripten:121: obj-emscripten/retroarch.o] Error 1

If you are updating the port, please update the hash.

What version of emscripten are you using?

Here's a working WASM fork of libretro/snes9x2005 that I found: snes9x2005-wasm (built files and demo).
