NAME
scidisasm - Disassembles all script resources into .script files
sciunpack - A tool for unpacking and converting SCI resource data
DESCRIPTION
FreeSCI is a portable interpreter for SCI games, such as the Space
Quest series (starting with SQ3) or Leisure Suit Larry (2 and sequels).
This man page describes the tools that come with FreeSCI. The main
executable (which you’re probably interesed in if you want to play SCI
games) is described in sciv(6).
SCIDISASM
The scidisasm program disassembles all script resources in SCI resource
files in the current directory into .script files.
It takes five optional command line switches: --version prints the
version number and exists; --help displays a short help message and
exists; --hexdump hex dumps all script resources; --verbose prints
additional disassembly information; --opcode-size prints opcode size
postfixes.
SCIUNPACK
sciunpack is a tool for unpacking, printing, and converting SCI
resource data
Usage: sciunpack [operation] [options] <resource.number>
Alternatively, the resource type and number can be specified as two
seperate options.
Available resources are: view, pic, script, text, sound, memory, vocab,
font, cursor, patch, bitmap, palette, cdaudio, audio, sync, sync,
message, map, heap.
If * is specified instead of <number>, all resources of given type will
be unpacked.
sciunpack supports the following operations:
--unpack, -U
This is the default action; it unpacks the specified resource.
--list, -L
Lists all available resources.
--words, -W
Prints all vocabulary words understood by the parser. See
--objects, -O
Outputs the full object hierarchy
--vocab, -V
This operation goes through several relevant ’vocab’ resources,
interprets their contents, and prints them sequentially. First,
all selector (variable/function) names are print, then all
opcodes, followed by the names of all kernel functions, and
finally the class ID/script lookup table.
--version
Prints the version number.
--help, -h
Displays a short help message.
Also, there are several options available:
--verbose, -v
Enables additional output.
--convert, -c
Forces sound resources to be converted to General MIDI on some
platforms, and script resources to be dissected.
--output-file <file>, -o<file>
Selects output file file.
--gamedir <dir>, -d<dir>
Read game resources from dir.
--with-header
Forces the SCI header to be written (default).
--without-header
Prevents the two SCI header bytes from being. written
--sort-alpha
Sorts in alphabetical order when listing words (-W)
--sort-group
Sorts by group IDs when listing words (-W)
As a default, ’resource.number’ is the output filename, unless
conversion is enabled (-c). With conversion, a few resource types are
treated specially:
- sound resources: will be converted to General MIDI, stored in
<number>.midi (this only works on GNU libc systems)
- script resources: will be dissected and stored in
<number>.script
SCRIPTDUMP
The scriptdump tool can be used to disassemble all selector methods
into SCI assembly. It takes no command line options and reads the
resource files from the current directory.
VOCABDUMP
This tool can be used to display kernel function and selector names.
It is obsolete.
