I am mainly selling retro games from a collection I've gathered in the past. I have cleaned the terminals and the cartridge itself. I have confirmed the initial operation by inserting the cartridge and checking for a display. [Boxed, No Manual] These items are about 40 years old, so there is some age-related deterioration. Please check the photos, and I will answer any questions you may have. I welcome combined shipping with other software! Please contact me before purchasing. I will discount the price by 100-200 yen for each additional item. When shipping, I will protect against rain by wrapping the item in cellophane and using bubble wrap or cardboard for sturdy packaging to prevent crushing.
