NAME

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.

SYNOPSIS

12       cc1541 [-niwfoVTPOlBMdtuxFsSeErbc45gqvh] image.[d64|d71|d81]

OPTIONS

15       -n diskname
16           Disk name, default=cc1541.
17
18       -i id
19           Disk ID, default=00 2a.
20
21       -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
25       -W localname
26           Like -w, but encode file in Transwarp format.
27
28       -K key
29           Set an encryption key for Transwarp files, a string of up to 29
30           characters.
31
32       -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
36       -o
37           Do not overwrite if file with same name exists already.
38
39       -V
40           Do not modify image unless it is in valid CBM DOS format.
41
42       -T filetype
43           Filetype for next file, allowed parameters are PRG, SEQ, USR, REL
44           and DEL. For DEL, the input file is ignored. Default is PRG.
45
46       -P
47           Set write protect flag for next file.
48
49       -O
50           Set open flag for next file.
51
52       -N
53           Force creation of a new directory entry, even if a file with the
54           same name exists already.
55
56       -l filename
57           Write loop file (an additional dir entry) to existing file to disk,
58           set filename with -f.
59
60       -B numblocks
61           Write the given value as file size in blocks to the directory for
62           the next file.
63
64       -M numchars
65           Hash computation maximum filename length, this must match loader
66           option FILENAME_MAXLENGTH in Krill’s Loader. Default is 16.
67
68       -m
69           Ignore filename hash collisions, without this switch a collision
70           results in an error.
71
72       -d track
73           Maintain a shadow directory (copy of the actual directory without a
74           valid BAM).
75
76       -t
77           Use dirtrack to also store files (makes -x useless) (default no).
78
79       -u numblocks
80           When using -t, amount of dir blocks to leave free (default=2).
81
82       -x
83           Don’t split files over dirtrack hole (default split files).
84
85       -F
86           Next file first sector on a new track (default=0). Any negative
87           value assumes aligned tracks and uses current sector + interleave.
88           After each file, the value falls back to the default. Not
89           applicable for D81.
90
91       -S value
92           Default sector interleave, default=10. At track end, reduces this
93           by 1 to accomodate large tail gap. If negative, no special
94           treatment of tail gap. Not applicable for D81.
95
96       -s value
97           Next file sector interleave, valid after each file. At track end,
98           reduces this by 1 to accomodate large tail gap. If negative, no
99           special treatment of tail gap. The interleave value falls back to
100           the default value set by -S after the first sector of the next
101           file. Not applicable for D81.
102
103       -e
104           Start next file on an empty track (default start sector is current
105           sector plus interleave).
106
107       -E
108           Try to fit file on a single track.
109
110       -r track
111           Restrict next file blocks to the specified track or higher.
112
113       -b sector
114           Set next file beginning sector to the specified value. Not
115           applicable for D81.
116
117       -c
118           Save next file cluster-optimized (d71 only).
119
120       -4
121           Use tracks 35-40 with SPEED DOS BAM formatting.
122
123       -5
124           Use tracks 35-40 with DOLPHIN DOS BAM formatting.
125
126       -g filename
127           Write additional g64 output file with given name.
128
129       -U mapping
130           Print PETSCII as Unicode (requires Unicode 13.0 font, e.g. UNSCII).
131           Use mapping 0 for ASCII output, 1 for upper case, 2 for lower case,
132           default is 0.
133
134       -q
135           Be quiet.
136
137       -v
138           Be verbose.
139
140       -h
141           Print commandline help.
