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       -f filename
26           Use filename as name when writing next file, use prefix # to
27           include arbitrary PETSCII characters (e.g. -f "START#a0,8,1").
28
29       -o
30           Do not overwrite if file with same name exists already.
31
32       -V
33           Do not modify image unless it is in valid CBM DOS format.
34
35       -T filetype
36           Filetype for next file, allowed parameters are PRG, SEQ, USR, REL
37           and DEL. For DEL, the input file is ignored. Default is PRG.
38
39       -P
40           Set write protect flag for next file.
41
42       -O
43           Set open flag for next file.
44
45       -N
46           Force creation of a new directory entry, even if a file with the
47           same name exists already.
48
49       -l filename
50           Write loop file (an additional dir entry) to existing file to disk,
51           set filename with -f.
52
53       -B numblocks
54           Write the given value as file size in blocks to the directory for
55           the next file.
56
57       -M numchars
58           Hash computation maximum filename length, this must match loader
59           option FILENAME_MAXLENGTH in Krill’s Loader. Default is 16.
60
61       -m
62           Ignore filename hash collisions, without this switch a collision
63           results in an error.
64
65       -d track
66           Maintain a shadow directory (copy of the actual directory without a
67           valid BAM).
68
69       -t
70           Use dirtrack to also store files (makes -x useless) (default no).
71
72       -u numblocks
73           When using -t, amount of dir blocks to leave free (default=2).
74
75       -x
76           Don’t split files over dirtrack hole (default split files).
77
78       -F
79           Next file first sector on a new track (default=0). Any negative
80           value assumes aligned tracks and uses current sector + interleave.
81           After each file, the value falls back to the default. Not
82           applicable for D81.
83
84       -S value
85           Default sector interleave, default=10. At track end, reduces this
86           by 1 to accomodate large tail gap. If negative, no special
87           treatment of tail gap. Not applicable for D81.
88
89       -s value
90           Next file sector interleave, valid after each file. At track end,
91           reduces this by 1 to accomodate large tail gap. If negative, no
92           special treatment of tail gap. The interleave value falls back to
93           the default value set by -S after the first sector of the next
94           file. Not applicable for D81.
95
96       -e
97           Start next file on an empty track (default start sector is current
98           sector plus interleave).
99
100       -E
101           Try to fit file on a single track.
102
103       -r track
104           Restrict next file blocks to the specified track or higher.
105
106       -b sector
107           Set next file beginning sector to the specified value. Not
108           applicable for D81.
109
110       -c
111           Save next file cluster-optimized (d71 only).
112
113       -4
114           Use tracks 35-40 with SPEED DOS BAM formatting.
115
116       -5
117           Use tracks 35-40 with DOLPHIN DOS BAM formatting.
118
119       -g filename
120           Write additional g64 output file with given name.
121
122       -q
123           Be quiet.
124
125       -v
126           Be verbose.

128       -h
