Great Baseball for Sega Mark III, tested and in good condition. - Game Title: Great Baseball - Platform: Sega Mark III - Software Condition: Clean - Operation Check: Tested and working - Release Year: 1985 Thank you for viewing. I sell a lot of retro games. I enjoy playing and selling them myself. [Game cartridge and instruction manual only] Although it's a product from about 40 years ago, it works without any problems. I have confirmed that the software starts up on my own game console. I provide as much information as possible not only in the description but also in the photos, so please check them. The cartridge terminals have been cleaned. There may be compatibility issues with the console. Don't give up; insert the cartridge firmly each time. Even without terminal restoration fluid, rubbing the terminals with a cotton swab with Magic Clean etc., and wiping them with a dry cotton swab can make it easier to read the game, so please try it. I welcome bundling with other software ♥ In that case, please be sure to contact me before purchasing. I will discount 100-200 yen for each additional item bundled ♥ When shipping, I will wrap the item in cellophane to protect against rain, and reinforce it with bubble wrap or cardboard for sturdy packaging to prevent crushing.
