This is the PC-9801 version of "Hokkaido 1984: Disappear in Okhotsk." The included booklet contains an interview with Yuji Horii. Regarding the software, operation has not been confirmed for the 5-inch disk due to the lack of a suitable operating environment. However, I have confirmed the following operations on my PC-9821 for the 3.5-inch disk: * Title screen startup * BGM * Save & Load Please also refer to the photos for the actual operating condition. ※ This is an old product from over 30 years ago. Please understand that perfect operation is not guaranteed. ※ The color may differ due to the angle and lighting.
