SEGA's silver cartridge, The Sword of Argos. - Brand: SEGA - Title: The Sword of Argos - License: TECMO - Cartridge Type: Silver Cartridge - Country of Manufacture: Japan - Compatible Models: MARK III / MASTER SYSTEM Thank you for viewing. I sell a lot of retro games. I enjoy playing and selling them myself. [Game Cartridge Only] It's a product from about 37 years ago, but it works fine. I have confirmed that the software starts up on the game consoles I own. I cannot guarantee the remaining battery life. Please check the photos as well as the description for as much information as possible. The cartridge terminals have been cleaned. There may be compatibility issues with the console. Don't give up, and insert it firmly each time. Even without terminal cleaner, you can make it easier to read by rubbing the terminals with a cotton swab with Magic Clean or similar, and wiping it with a dry cotton swab. Please try it. I welcome combining with other software ♥ In that case, please be sure to contact me before purchasing. I will discount 100-200 yen for each additional item ♥ When shipping, I will wrap it in cellophane to protect it from rain, and reinforce it with bubble wrap or cardboard for sturdy packaging to prevent crushing.
