Famicom Disk System All Night Nippon Super Mario Bros. Disk System All Night Nippon Super Mario Bros. Domestic genuine product. I bought it at a store in Akihabara a few years ago. The serial number of the disk is also a genuine product number. It is a used item stored by an individual. It will be packed with bubble wrap and shipped anonymously in a cardboard box. Returns are not accepted to prevent replacement. I will sell it to those who are okay with this. In addition, rare retro game software is on sale. #lain's game room (retro games, new and unopened) #Nintendo #Famicom #All Night Nippon #Genuine product #Mario Brothers #Disk System #mario #famicom #nes #FC #fc #nintendo #game #NES
