cc1541 - Man Page

A tool for creating Commodore 1541 Floppy disk images in D64, D71 or D81 format with custom sector interleaving etc. Also supports extended tracks 35-40 using either SPEED DOS or DOLPHIN DOS BAM-formatting.

Synopsis

cc1541 [options] image.[d64|d71|d81]

Options

-n diskname

Disk name, default=cc1541.

-i id

Disk ID, default=00 2a.

-H message

Hidden BAM message. Only for D64 (up to 85 chars) or SPEED DOS (up to 20 chars).

-w localname

Write local file to disk, if filename is not set then the local name is used. After file written, the filename is unset.

-W localname

Like -w, but encode file in Transwarp format.

-K key

Set an encryption key for Transwarp files, a string of up to 29 characters.

-f filename

Use filename as name when writing next file, use prefix # to include arbitrary PETSCII characters (e.g. -f "START#a0,8,1").

-o

Do not overwrite if file with same name exists already.

-V

Do not modify image unless it is in valid CBM DOS format.

-T filetype

Filetype for next file, allowed parameters are PRG, SEQ, USR, REL and DEL, or a decimal number between 0 and 255. Default is PRG.

-P

Set write protect flag for next file.

-O

Set open flag for next file.

-N

Force creation of a new directory entry, even if a file with the same name exists already.

-l filename

Write loop file (an additional dir entry) to existing file to disk, set filename with -f.

-L

Add dir entry without writing file (track and sector will be 0), requires a filename given with -f.

-B numblocks

Write the given value as file size in blocks to the directory for the next file.

-M numchars

Hash computation maximum filename length, this must match loader option FILENAME_MAXLENGTH in Krill’s loader. Default is 16.

-m

Ignore filename hash collisions, without this switch a collision results in an error.

-d track

Maintain a shadow directory (copy of the actual directory without a valid BAM).

-t

Use directory track to also store files (makes -x useless) (default no).

-u numblocks

When using -t, amount of dir blocks to leave free (default=2).

-x

Don’t split files over directory track hole (default split files).

-F

Next file first sector on a new track (default=0). Any negative value assumes aligned tracks and uses current sector + interleave - value. After each file, the value falls back to the default. Not applicable for D81.

-S value

Default sector interleave, default=10. Not applicable for D81.

-s value

Next file sector interleave, valid after each file. The interleave value falls back to the default value set by -S after the first sector of the next file. Not applicable for D81 or Transwarp files.

-e

Start next file on an empty track (default start sector is current sector plus interleave).

-E

Try to fit file on a single track.

-r track

Restrict next file blocks to the specified track or higher.

-b sector

Set next file beginning sector to the specified value. Not applicable for D81 or Transwarp files.

-A value

Select allocation strategy for Transwarp files (default 1). 0: allocate in the order given on the commandline. 1: save disk space by reordering transwarp files.

-c

Save next file cluster-optimized (d71 only).

-4

Use tracks 35-40 with SPEED DOS BAM formatting.

-5

Use tracks 35-40 with DOLPHIN DOS BAM formatting.

-R level

Try to restore deleted and formatted files. level 0: Only restore all dir entries without touching any t/s links. level 1: Fix dir entries for files with valid t/s chains. level 2: Also add wild sector chains with valid t/s chains. level 3: Also fix dir entries with invalid t/s chains. level 4: Also add and fix wild invalid t/s chains. level 5: Also add reasonable wild single blocks.

-g filename

Write additional g64 output file with given name.

-a

Print command line options that would create the same directory as the one in the given image (for directory art import).

-U mapping

Print PETSCII as Unicode (requires Unicode 13.0 font, e.g. UNSCII). Use mapping 0 for ASCII output, 1 for upper case, 2 for lower case, default is 0.

-q

Be quiet.

-v

Be verbose.

-h

Print command line help.

Exit Status

0

Success.

-1

Failure.
