Game Boy software "Shin SD Gundam Gaiden: Knight Gundam" is here. Software only. Please consider this item, understanding that it is a used product. Please check the photos for scratches, stains, etc. I confirmed it boots on a Game Boy Advance SP, but please understand that it may have poor readability due to its age. I may need some time to ship due to work. I will wrap it in bubble wrap for shipping.
