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.
10
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 -H message
22 Hidden BAM message. Only for D64 (up to 85 chars) or SPEED DOS (up
23 to 20 chars).
24 -w localname
26 Write local file to disk, if filename is not set then the local
27 name is used. After file written, the filename is unset.
28 -W localname
30 Like -w, but encode file in Transwarp format.
31 -K key
33 Set an encryption key for Transwarp files, a string of up to 29
34 characters.
35 -f filename
37 Use filename as name when writing next file, use prefix # to
38 include arbitrary PETSCII characters (e.g. -f "START#a0,8,1").
39 -o
41 Do not overwrite if file with same name exists already.
42 -V
44 Do not modify image unless it is in valid CBM DOS format.
45 -T filetype
47 Filetype for next file, allowed parameters are PRG, SEQ, USR, REL
48 and DEL, or a decimal number between 0 and 255. Default is PRG.
49 -P
51 Set write protect flag for next file.
52 -O
54 Set open flag for next file.
55 -N
57 Force creation of a new directory entry, even if a file with the
58 same name exists already.
59 -l filename
61 Write loop file (an additional dir entry) to existing file to disk,
62 set filename with -f.
63 -L
65 Add dir entry without writing file (track and sector will be 0),
66 requires a filename given with -f.
67 -B numblocks
69 Write the given value as file size in blocks to the directory for
70 the next file.
71 -M numchars
73 Hash computation maximum filename length, this must match loader
74 option FILENAME_MAXLENGTH in Krill’s loader. Default is 16.
75 -m
77 Ignore filename hash collisions, without this switch a collision
78 results in an error.
79 -d track
81 Maintain a shadow directory (copy of the actual directory without a
82 valid BAM).
83 -t
85 Use directory track to also store files (makes -x useless) (default
86 no).
87 -u numblocks
89 When using -t, amount of dir blocks to leave free (default=2).
90 -x
92 Don’t split files over directory track hole (default split files).
93 -F
95 Next file first sector on a new track (default=0). Any negative
96 value assumes aligned tracks and uses current sector + interleave -
97 value. After each file, the value falls back to the default. Not
98 applicable for D81.
99 -S value
101 Default sector interleave, default=10. Not applicable for D81.
102 -s value
104 Next file sector interleave, valid after each file. The interleave
105 value falls back to the default value set by -S after the first
106 sector of the next file. Not applicable for D81 or Transwarp files.
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 or Transwarp files.
121 -A value
123 Select allocation strategy for Transwarp files (default 1). 0:
124 allocate in the order given on the commandline. 1: save disk space
125 by reordering transwarp files.
126 -c
128 Save next file cluster-optimized (d71 only).
129 -4
131 Use tracks 35-40 with SPEED DOS BAM formatting.
132 -5
134 Use tracks 35-40 with DOLPHIN DOS BAM formatting.
135 -R level
137 Try to restore deleted and formatted files. level 0: Only restore
138 all dir entries without touching any t/s links. level 1: Fix dir
139 entries for files with valid t/s chains. level 2: Also add wild
140 sector chains with valid t/s chains. level 3: Also fix dir entries
141 with invalid t/s chains. level 4: Also add and fix wild invalid t/s
142 chains. level 5: Also add reasonable wild single blocks.
143 -g filename
145 Write additional g64 output file with given name.
146 -a
148 Print command line options that would create the same directory as
149 the one in the given image (for directory art import).
150 -U mapping
152 Print PETSCII as Unicode (requires Unicode 13.0 font, e.g. UNSCII).
153 Use mapping 0 for ASCII output, 1 for upper case, 2 for lower case,
154 default is 0.
155 -q
157 Be quiet.
158 -v
160 Be verbose.
161 -h
163 Print command line help.
164
166 0
167 Success.
168 -1
170 Failure.
