If I were you, I wouldn't do such complicated things. First of all, I think someone has already done it before you. After all, there is even Retro Arcade MachinesRetro Arcade Machines. And on the phone moreover there will already be a ready-made game. So do not bother. Create something more necessary. Of course no one has the right to tell you but to sound advice is better to listen.

I still play consoles, too. It's so cool! Can you tell me what kind of console you have? And when do you plan to finish your project?

I would like to know more about that. There are a lot of favorite games on consoles and I would like to transfer them to the phone. If you can do this, please share the result. I would really like to learn how to do this.
