I sell a lot of retro games. I enjoy playing and selling them myself. [Game Cartridge Only] Although it's a product from about 20 years ago, it works without problems. I have confirmed that the software starts up on my own game console. 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. Please insert it firmly each time, don't give up. Even without terminal cleaner, you can try rubbing the terminals with a cotton swab and Magic Clean, etc., and wiping them with a dry cotton swab to make them easier to read. I welcome combining with other software ♥ 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.
