I am selling a large collection of retro games that I have collected in the past. Please read my profile before purchasing. I have cleaned the terminals and the cartridge itself. I have confirmed the initial operation by inserting the cartridge and checking if the screen appears. I have tested it using the actual machine and Retro Freak. I cannot guarantee the remaining battery life. [Box and Instruction Manual Included] Although it is a product from about 35 to 40 years ago, there is some deterioration due to age. The cartridge is in good condition and works. Please check the photos and feel free to ask any questions. I welcome combined shipping 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 reinforce it with bubble wrap or cardboard for sturdy packaging to prevent crushing.
