Space Invaders Arcade is a hack of the game (it plays exactly the same as the original 2600 version), having changed game sprites, as the invaders, players' laser cannons, bunkers, and the Command Alien Ship look different (the latter of which is also smaller), as they were all changed to closer resemble the arcade original. The color of the earth was also changed to black (the original colors of black, white, green and orange are all that's present) and some sounds were changed. The hack was created by Rob Kudla.
