It is an NES game emulator. I know there are a lot of em in the market, so why is the use. Then I must say there are a lot of facebooks there, then why had whatsapp. I am making this software for learning. Its at the development stage now, so no use for writing long stuff now, its just that its at development, so if you are a potential contributor then you are lucky, as code will be easy to understand now. You may see the code, may see the CONTRIBUTING.md to learn more about contributing to this project if you want to.
