【Operation Not Confirmed】Koi-Koi Daisakusen MJ2 Popular Competitive Hanafuda! This is Koi-Koi Daisakusen MJ2, a popular competitive Hanafuda game! It's a Windows software from about 20 years ago. I haven't been able to confirm its operation because I don't have a PC with the appropriate specifications. Please consider purchasing it as a collector's item. Since the operation hasn't been confirmed and there is damage to the disc and case, the condition is listed as "Poor". Please understand this before purchasing. Feel free to ask for additional photos or negotiate. Due to the thickness, it will be shipped with simple packaging, only with measures to prevent water damage. Search words: Rare game / Rare game
