Working
* Game is fully playable (1 player).
* Clock timing is fairly okay, could use some work.
* All instructions needed for Space Invaders implemented.
* Some sounds are working.

TODO
* Player 2 controls.
* Rest of the sounds.
* Maybe fine tune the clock timing.
* Look into supporting Balloon Bomber and other Intel 8080 games.
* Support for loading rom, right now it's just hardcoded.
