Lightly used game, tested to work on an original Atari 2600 as well as the 2600+ and 7800+.
  
The backstory of Sinistar (from Atari Protos)…
 
"It's simply amazing how Atari managed to capture the action and excitement of Sinistar and condense it into the tiny 2600.  The graphics are excellent (by 2600 standards), and the controls are sharp and precise.  The only places Atari had to compromise on were the voice (which was impossible to reproduce on the 2600), and the controls which had to be simplified slightly due to the 2600 only having one fire button.  In the Arcade there were separate fire buttons for shooting and dropping Sinibombs, but on the 2600 your ship has auto fire, so the fire button drops the Sinibombs instead.  This really doesn't take away from the gameplay since you were always shooting in the arcade anyway (your fingers just got a bit of an extra work out).
 
So why wasn't Sinistar released?  Around the time Sinistar was being completed (early 1984), the video game market was crumbling fast and many new games never got released.  Atari had already commissioned artwork for Sinistar, and the game seems to have been nearly completed so it was probably a matter of weeks before Sinistar would be finalized and ready for production.  Perhaps playtesters thought the game was too difficult or wasn't polished enough, but whatever the reason Sinistar got shelved and was forgotten about."
