6 cc1541 - A tool for creating Commodore 1541 Floppy disk images in D64,
7 D71 or D81 format with custom sector interleaving etc. Also supports
8 extended tracks 35-40 using either SPEED DOS or DOLPHIN DOS
9 BAM-formatting.

12 cc1541 [options] image.[d64|d71|d81]
13
15 -n diskname
16 Disk name, default=cc1541.
17 -i id
19 Disk ID, default=00 2a.
20 -w localname
22 Write local file to disk, if filename is not set then the local
23 name is used. After file written, the filename is unset.
24 -W localname
26 Like -w, but encode file in Transwarp format.
27 -K key
29 Set an encryption key for Transwarp files, a string of up to 29
30 characters.
31 -f filename
33 Use filename as name when writing next file, use prefix # to
34 include arbitrary PETSCII characters (e.g. -f "START#a0,8,1").
35 -o
37 Do not overwrite if file with same name exists already.
38 -V
40 Do not modify image unless it is in valid CBM DOS format.
41 -T filetype
43 Filetype for next file, allowed parameters are PRG, SEQ, USR, REL
44 and DEL, or a decimal number between 0 and 255. Default is PRG.
45 -P
47 Set write protect flag for next file.
48 -O
50 Set open flag for next file.
51 -N
53 Force creation of a new directory entry, even if a file with the
54 same name exists already.
55 -l filename
57 Write loop file (an additional dir entry) to existing file to disk,
58 set filename with -f.
59 -L
61 Add dir entry without writing file (track and sector will be 0),
62 requires a filename given with -f.
63 -B numblocks
65 Write the given value as file size in blocks to the directory for
66 the next file.
67 -M numchars
69 Hash computation maximum filename length, this must match loader
70 option FILENAME_MAXLENGTH in Krill’s Loader. Default is 16.
71 -m
73 Ignore filename hash collisions, without this switch a collision
74 results in an error.
75 -d track
77 Maintain a shadow directory (copy of the actual directory without a
78 valid BAM).
79 -t
81 Use directory track to also store files (makes -x useless) (default
82 no).
83 -u numblocks
85 When using -t, amount of dir blocks to leave free (default=2).
86 -x
88 Don’t split files over directory track hole (default split files).
89 -F
91 Next file first sector on a new track (default=0). Any negative
92 value assumes aligned tracks and uses current sector + interleave.
93 After each file, the value falls back to the default. Not
94 applicable for D81.
95 -S value
97 Default sector interleave, default=10. At track end, reduces this
98 by 1 to accommodate large tail gap. If negative, no special
99 treatment of tail gap. Not applicable for D81.
100 -s value
102 Next file sector interleave, valid after each file. At track end,
103 reduces this by 1 to accommodate large tail gap. If negative, no
104 special treatment of tail gap. The interleave value falls back to
105 the default value set by -S after the first sector of the next
106 file. Not applicable for D81.
107 -e
109 Start next file on an empty track (default start sector is current
110 sector plus interleave).
111 -E
113 Try to fit file on a single track.
114 -r track
116 Restrict next file blocks to the specified track or higher.
117 -b sector
119 Set next file beginning sector to the specified value. Not
120 applicable for D81.
121 -c
123 Save next file cluster-optimized (d71 only).
124 -4
126 Use tracks 35-40 with SPEED DOS BAM formatting.
127 -5
129 Use tracks 35-40 with DOLPHIN DOS BAM formatting.
130 -R level
132 Try to restore deleted and formatted files. level 0: Only restore
133 all dir entries without touching any t/s links. level 1: Fix dir
134 entries for files with valid t/s chains. level 2: Also add wild
135 sector chains with valid t/s chains. level 3: Also fix dir entries
136 with invalid t/s chains. level 4: Also add and fix wild invalid t/s
137 chains. level 5: Also add reasonable wild single blocks.
138 -g filename
140 Write additional g64 output file with given name.
141 -a
143 Print command line options that would create the same directory as
144 the one in the given image (for directory art import).
145 -U mapping
147 Print PETSCII as Unicode (requires Unicode 13.0 font, e.g. UNSCII).
148 Use mapping 0 for ASCII output, 1 for upper case, 2 for lower case,
149 default is 0.
150 -q
152 Be quiet.
153 -v
155 Be verbose.
156 -h
158 Print command line help.
159
161 0
162 Success.
163 -1
165 Failure.
