Custom built libretro cores

Notes

All forked code is here:

https://github.com/thelamer/retrostash

We build these cores using emsdk 1.39.5.

Basic build instructions

git clone https://github.com/emscripten-core/emsdk.git
cd emsdk
./emsdk install 1.39.5
./emsdk activate 1.39.5
Follow instructions for sourcing paths to shell

git clone https://github.com/thelamer/retrostash.git
cd retrostash/libretro-fceumm
emmake make -f Makefile -j6 platform=emscripten
cd ../Retroarch/dist-scripts
cp ../../libretro-fceumm/fceumm_libretro_emscripten.bc .
emmake ./dist-cores.sh emscripten

Resulting build output will be in ../pkg/emscripten. After these files are built run the following command to utilize the pre-initiated audio context used by libretrojs: (needed for safari compatibility)

sed -i 's/context:undefined/context:readyAudioContext/g'

Built at commit 1efc0309b65ce77ad5121a6c5f329ad9e26a6ded before breaking filestream changes. Slight makefile tweaks for static chd support:

Need to swap the static linking include in Makefile.common

Tweaks for memory limits.
