The FDS format (file name suffix .fds) is a way to store Famicom Disk System disk data. It consists of the following sections, in order:
- Header (16 bytes)
- Disk data (65500 * x bytes)
The format of the header is as follows:
- 0-3: Constant $46 $44 $53 $1A ("FDS" followed by MS-DOS end-of-file)
- 4: Number of disk sides in 65500 byte units
- 5-15: Zero filled
