This is an emscripten port of https://github.com/visualboyadvance-m/visualboyadvance-m. It's using custom bindings to get pixel/audio/input/savegame data into & out of the emulator. (as opposed to using emstripten's built in file system and sdl support).

Eventually, it should work on all browsers that support WebGL. Currently, it also requires localStorage (so Safari private browsing won't work).

Build

1. npm install.
2. in a separate terminal window:
   • download Emscripten from https://github.com/emscripten-core/emsdk. (Download as zip)
   • in emscripten, emsdk install latest && emsdk activate
   • (confirmed working in emsdk commit 0490c5f with sdk-1.37.1-64bit installed)
   • Run node build --opt (the --opt is production mode). This takes a while.
3. Run npm run webpack.
4. Open build/index.html.

(the separate terminal window is because emscripten comes bundled with a really old version of node)

TODOs

• Fix frame drop problems
• Fix bug where audio stops if headphones are unplugged
• Google Drive sync for save games
• Touch controls
• Enable frameskip on slow devices
• Ability to load BIOS
• UI for loading ROMs from URLs
• Support for roms in zip files
• Cache roms in HTML5 FS
• Mute button (should disable audio emulation)
