What is 500 file? How to open 500 files?
File type specification:
The Family Computer Disk System was released on February 21, 1986 by Nintendo as a peripheral for the Family Computer ("Famicom") console in Japan. It was a unit that used proprietary floppy disks (called "disk cards") for data storage. It was announced, but never released, for the North American Nintendo Entertainment System.
The device was connected to the Famicom deck by plugging a modified cartridge known as the RAM Adapter into the system's cartridge port, which attached via a supplied cable to the disk drive. The RAM adapter contained 32 kilobytes of RAM for temporary program storage, 8 kilobytes of RAM for tile and sprite data storage, and an ASIC known as the 2C33.
The ASIC acted as a disk controller for the floppy drive, and also included additional sound hardware featuring primitive wavetable synthesis and FM synthesis capabilities. The disk cards used were double-sided, with a total capacity of 896 kilobits or 112 kilobytes per disk. Many games spanned both sides of a disk, requiring the user to switch sides at some point during gameplay.
A few games used two full disks (four sides). The Disk System was capable of running on six C-cell batteries or the supplied AC adapter. Batteries would usually last 5 months on daily game play. The battery option was included due to the likelihood of a standard set of AC plugs already being occupied by a Famicom and a television.
