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.

For some reason I have little faith that after reading a couple of articles you can fully work in this field. You need to learn and learn. And only after that will you be successful.
