8/7/2023 0 Comments Amiga floppy disk formatAn HDF file contains a byte dump of all sectors of a hard disk, just as an ADF file contains a byte dump of all sectors of a floppy disk. HDF files are the equivalent of ADF files for hard disks. If the floppy disk has sufficient space for all files, the disk can be used inside the emulator or exported, e.g., in form of an ADF file. When a directory is provided by drag-and-drop, the emulator tries to write all files of the directory to an empty floppy disk. VAmiga allows directories of the host computer to be used in the form of floppy disks. Inserting such a floppy disk makes sense only if you use special software that can read such floppy disks. To figure out what is happening and why this command works, we need to know a little about the format of a floppy disk. Image files are floppy disks in MS-DOS format. We put our 720K floppy disk into the floppy drive and type format a: /t:80 /n:9, which will the format the disk in the floppy drive in a way that the ST can read and understand. It also makes the floppy bootable by adding a boot block and a startup sequence that loads the executable. When such a file is passed to the emulator, vAmiga creates a floppy disk on-the-fly and copies the executable to it. VAmiga also supports pure Amiga executables. Thus, you will find many demos encoded in this format. The format is very popular in the demo scene. However, the internal representation is much more complicated. ![]() For example, the format is able to store the uninterpreted MFM data stream of single tracks or the whole disk.ĭMS files store a digital image of an Amiga floppy disk, just like ADFs. ![]() It has a much more complicated structure than the standard ADF format and offers different methods to represent track data. ![]() The extended ADF format has been created to store copy-protected disks or disks that were formatted in a non-standard format. The ADF format is the most widely used format for Amiga floppy disks and almost all non-copy-protected titles are available in form of ADF files. The format is extremely simple in structure, since it does not store any header information. VAmiga supports the following file formats for floppy disks:ĪDF files contain a byte dump of all sectors of an Amiga diskette.
