Yama-chan & Raymond TV Tokyo Oha-Suta (Nintendo) Game Boy & Color Common Software No box, no instruction manual Sold by Epoch Co., Ltd. Since I don't have a Game Boy, I haven't been able to confirm its operation. I cannot guarantee the quality and cannot accept returns due to defects in the item. Please consider this only if you understand. There may be existing data inside. I remember this item being about 25 years old. It was left inside a Game Boy Color. Kouichi Yamadera is young, but I remember he only appeared as a mini-character that I couldn't even recognize as Yamadera-san. I vaguely remember it being a children's game where you avoided enemies and cleared courses by warping from door to door. This is from my childhood memories, so I'm not certain. It will be shipped via Yu-Packet Post Mini (may be changed to Nekopos).
