I sell a lot of retro games. I enjoy playing and selling them myself. Please read my profile before purchasing. [Game cartridge only] It's a product from about 30 years ago, but it works without any 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 information. The cartridge terminals have been cleaned. There may be compatibility issues with the console. Please insert the cartridge firmly each time, and don't give up. Even without terminal revival fluid, you can try rubbing the terminals with a cotton swab and Magic Clean, then wiping them with a dry cotton swab to make it easier to read. I welcome combining with other software♥ Please 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 other moisture, and I will reinforce it with bubble wrap or cardboard for sturdy packaging to prevent crushing.
