jsSMS is an emulator for Sega Master System & Game Gear ROMs written in JavaScript and designed to be fast on mobile browsers.
Originally, this is a JavaScript port of JavaGear by Chris White.

The code then evolved from a basic interpreter to a complex recompiler able to run on mobile at full speed.
The recompilation code is located in src/compiler folder as well as technical insights.
Video of the talk about JSSMS I gave at Reject.js 2013. There are also the slides in HTML.
- Sound is supported on the outdated dynamicaudio branch.
- Though state save and load functions are ported, there are not used and should be more JavaScript friendly (using JSON for example, see JSNES for an example of implementation).
- Lightgun is not yet supported.
- The recompiler is not compatible with Closure Compiler in advanced optimizations mode and will likely never be.
Many parts of the script are borrowed from JSNES, a NES emulator in JavaScript by Ben Firsh.

- Support latest IE.
- Experiment with web workers for recompiled code generation.
- Experiment with generator for calling interrupts.
- Experiment with asm.js.
