683 Sectors (= 35 Tracks) with error info.

683 Sectors (= 35 Tracks) without error info.

While the extra tracks are not within the original specification such disks are readable with most C1541 drives (Note: Reading does not require special software.).Ĭurrently there are four different types of *.D64 formats: With the use of special software it is possible to format and write disks with up to 40 (or rarely even 42) tracks. A disk that was formatted by using the standard C1541 command NEW will have 35 tracks containing a total of 683 sectors. In order to be able to deal with bad sectors the *.D64 format optionally features an additional error byte per sector.

On a C1541 formatted disk (and thus also in a *.D64 file) each sector consists of 256 Byte.

The *.D64 file format is a 1:1 copy of all sectors as they appear on a floppy disk. This is a clear advantage over the (unfortunately more widespread) *.D64 format. The *.X64 disk image format was originally created by Teemu Rantanen for use in X64.Īs *.X64 uses a well defined header the emulator is able to make sure that only valid files are used. Description of the Disk Image (in ASCII or ISO Latin/1)įor more information on DiskImage see also: *.D64. Flag for Error (precise meaning unclear) (unused) This makes it the recommended file format for single files. As it has a magic constant at the head of the file it also enables the emulator to make sure that no invalid files are used. The *.P00 format is a flexible file format, that is able to support all common types of C64 files. Since they are so rare, a simple LHA-document icon is used for all types of LHA compressed files. LHA compressed files do not carry a special icon indicating the file type. A plain icon for uncompressed files, a icon with a yellow ribbon to indicate GZ compression and an icon with a red ribbon for ZIP compression. Since Power64 allows the use of GZ/ZIP or LHA compressed files, many of the icons come in three subtypes. Power64 uses different icons for the various file format. If you are only interested in playing your favorite C64 game, then you do not need to worry about these details. It is intended for the interested programmer, who might wish to learn the internal workings of the emulator. This section describes all the common file formats in the field of Commodore 64 emulation.
