Sinistar for Atari 5200
Sinistar was a fairly popular arcade game released by Williams Electronics in 1983. Interestingly, in a time when arcade to home ports were very common, no home port of Sinistar was released until more than a decade later as part of several of the Midway compilations for a variety of systems. Versions for the Atari 2600 and Atari 8-bit computer line were planned and mostly completed but for some reason never released. This probably had a lot to do with the video game crash and the decline in popularity of home video games at that time. 8-bit computer games were quite popular still but the Atari line was rapidly losing market share to the Commodore 64 and the Apple II.
Thanks to the magic of the internet, the nearly completed Atari 8-bit version has been found, ported to the Atari 5200 and released. For more information on this, to order a cartridge, or to download an image for emulators, see https://atariage.com/store/index.php?l=product_detail&p=955
