Game Boy game software: Yoshi's Egg. Cartridge only. Stored at home, there are scratches and dirt, so please check the images and purchase if you understand. Operation has been confirmed, and I was able to play it without any problems. Also, bulk purchases are welcome. 100 yen off from the second item. Shipping is planned via regular mail, but if you wish for anonymous shipping (Yu-Yu Mercari Mail +55 yen), please comment. In that case, I will ship it with a plastic case. Thank you.
