Tested Zaxxon, a 32KB game cartridge for the SG-1000. - Game Title: Zaxxon - Platform: SG-1000 - ROM Size: 32KB - Condition: Tested and working, terminals cleaned - Manual: None Thank you for viewing. I am mainly selling a large collection of retro games that I have collected in the past. I have also cleaned the terminals and the cartridge itself. I have confirmed the initial operation by inserting the cartridge and checking if the screen appears. [With Box] Although it is a product from about 40 years ago, there is some deterioration due to age. Please check the photos, and I will answer any questions you may have about anything you don't understand. I welcome combined shipping with other software ♥ Please contact me before purchasing.
