The Famicom Disk System was released exclusively in Japan in February 21, 1986 as a peripheral for the Family Computer ("Famicom") console in Japan. Larger than the hardware it's designed for, the Famicom Disk System used Floppy Disks instead of cartridges. 4.5 million units were sold in Japan, and though it was announced for the United States, Nintendo of America eventually decided against releasing it. Diskun was the mascot for the hardware.
Mario and Luigi appear in Famicom Disk System's BIOS. There, Luigi would "turn off" the light and Mario would turn it on again, with a different color each time, until a disk is inserted. Mario's color scheme is similar to the one from Donkey Kong, while Luigi's color scheme is the same from Super Mario Bros..
Until 2003, there were kiosks called "Disk Writers" where players could write games on disks. Some games, like Kaettekita Mario Bros., were exclusive to Disk Writers. For unknown reasons, the writing service for Time Twist: Rekishi no Katasumi de... stopped in 2002, a year before the Disk Writers were retired. While not being used, the disk writer screen would show a demonstration video featuring Mario and Luigi showing how to write a game using pixelated versions of Famicom Disk System and Disk Writer.
Diskun, the mascot for the Famicom Disk System, became quite popular in Japan. Merchandise featuring the character was produced in the country and a trophy of it was present in the Nintendo GameCube video game Super Smash Bros. Melee. Diskun also made a brief appearance in the Famicom video games Smash Ping Pong, Famicom Golf: Japan Course, Famicom Golf: U.S. Course and Nakayama Miho no Tokimeki High School (released only in Japan) and later in WarioWare: Smooth Moves, on a poster in a game shop, and WarioWare Touched!, as a tattoo on a guitarist from a microgame. The song that plays when the Disk System is turned on is a sample song for the Rock Organ in Daigasso! Band Brothers DX. Also, the same song plays on a very low speed on Game Cube menu.
