PacMan and Space invaders are old classic Atari games. One has nothing to do with the other, there’s no cross overs. That didn’t exist back in the early 80’s I own and played both the original PacMan and Space Invaders. As a matter of fact, all I need is go, power up my Atari, grab the game cartridge, blow on it, slap into the slot and start playing.
