=======

|
Utilities to list files on and extract files from Atari 8-bit emulator disk
|
|
images. Eventually, I hope to add support for these images to pyfilesystem.

Supported Disk Image Formats
|
|
============================
|
|
|
|
* ``XFD``: XFormer images, basically raw disk dumps
|
|
* ``ATR``: Nick Kennedy's disk image format; includes 16 byte header
|
|
|
|
|
|
Example Usage
|
|
=============
|
|
|
|
To extract all non SYS files while converting to lower case, use::
|
|
|
|
$ python atrcopy.py /tmp/GAMES1.ATR -x -l -n
|
|
GAMES1.ATR
|
|
File #0 : *DOS SYS 039 : skipping system file dos.sys
|
|
File #1 : *MINER2 138 : copying to miner2
|
|
File #2 : *DEFENDER 132 : copying to defender
|
|
File #3 : *CENTIPEDE 045 : copying to centiped.e
|
|
File #4 : *GALAXIAN 066 : copying to galaxian
|
|
File #5 : *AUTORUN SYS 005 : skipping system file autorun.sys
|
|
File #6 : *DIGDUG 133 : copying to digdug
|
|
File #7 : *ANTEATER 066 : copying to anteater
|
|
File #8 : *ASTEROIDS 066 : copying to asteroid.s
|
|
|
|
|
|
Example on Mac OS X
|
|
-------------------
|
|
|
|
OS X supplies python with the operating system so you shouldn't need to install
|
|
a framework version from python.org.
|
|
|
|
To prevent overwriting important system files, it's best to create a working
|
|
folder: a new empty folder somewhere and do all your testing in that folder.
|
|
For this example, create a folder called ``atrtest`` in your ``Documents``
|
|
folder. Put a few disk images in this directory to use for testing.
|
|
|
|
Download or copy the file ``atrcopy.py`` and put it the ``Documents/atrtest``
|
|
folder.
|
|
|
|
Since this is a command line programe, you must start a Terminal by double
|
|
clicking on Terminal.app in the ``Applications/Utilities`` folder in
|
|
the Finder. When Terminal opens, it will put you in your home folder
|
|
automatically. Go to the ``atrtest`` folder by typing::
|
|
|
|
cd Documents/atrtest
|
|
|
|
You should see the file ``atrcopy.py`` as well as the other ATR images you
|
|
placed in this directory by using the command::
|
|
|
|
ls -l
|
|
|
|
For example, you might see::
|
|
|
|
mac:~/Documents/atrtest $ ls -l
|
|
-rw-r--r-- 1 rob staff 92176 May 18 21:57 GAMES1.ATR
|
|
-rwxr-xr-x 1 rob staff 8154 May 18 22:36 atrcopy.py
|
|
|
|
Now, run the program by typing ``python atrcopy.py YOURFILE.ATR`` and you should
|
|
see the contents of the ``ATR`` image in the familiar Atari DOS format::
|
|
|
|
mac:~/Documents/atrtest $ python atrcopy.py GAMES1.ATR
|
|
GAMES1.ATR
|
|
File #0 : *DOS SYS 039
|
|
File #1 : *MINER2 138
|
|
File #2 : *DEFENDER 132
|
|
File #3 : *CENTIPEDE 045
|
|
File #4 : *GALAXIAN 066
|
|
File #5 : *AUTORUN SYS 005
|
|
File #6 : *DIGDUG 133
|
|
File #7 : *ANTEATER 066
|
|
File #8 : *ASTEROIDS 066
|
|
|
|
Without any additional arguments, it will not extract files. To actually pull
|
|
the files out of the ``ATR`` image, you need to specify the ``-x`` command line
|
|
argument::
|
|
|
|
mac:~/Documents/atrtest $ python atrcopy.py -x GAMES1.ATR
|
|
GAMES1.ATR
|
|
File #0 : *DOS SYS 039 : copying to DOS.SYS
|
|
File #1 : *MINER2 138 : copying to MINER2
|
|
File #2 : *DEFENDER 132 : copying to DEFENDER
|
|
File #3 : *CENTIPEDE 045 : copying to CENTIPED.E
|
|
File #4 : *GALAXIAN 066 : copying to GALAXIAN
|
|
File #5 : *AUTORUN SYS 005 : copying to AUTORUN.SYS
|
|
File #6 : *DIGDUG 133 : copying to DIGDUG
|
|
File #7 : *ANTEATER 066 : copying to ANTEATER
|
|
File #8 : *ASTEROIDS 066 : copying to ASTEROID.S
|
|
|
|
There are other flags, like the ``-l`` flag to covert to lower case, and the
|
|
``--xex`` flag to add the `.XEX` extension to the filename, and ``-n`` to skip
|
|
DOS files. So a full example might be::
|
|
|
|
mac:~/Documents/atrtest $ python atrcopy.py -n -l -x --xex GAMES1.ATR
|
|
GAMES1.ATR
|
|
File #0 : *DOS SYS 039 : skipping system file dos.sys
|
|
File #1 : *MINER2 138 : copying to miner2.xex
|
|
File #2 : *DEFENDER 132 : copying to defender.xex
|
|
File #3 : *CENTIPEDE 045 : copying to centipede.xex
|
|
File #4 : *GALAXIAN 066 : copying to galaxian.xex
|
|
File #5 : *AUTORUN SYS 005 : skipping system file autorun.sys
|
|
File #6 : *DIGDUG 133 : copying to digdug.xex
|
|
File #7 : *ANTEATER 066 : copying to anteater.xex
|
|
File #8 : *ASTEROIDS 066 : copying to asteroids.xex
|
|
|
|

Command Line Arguments
|
|
----------------------
|
|
|
|
The available command line arguments are summarized using the standard ``--

|
|
|
|
$ python atrcopy.py --help
|
|
usage: atrcopy.py [-h] [-v] [-l] [--dry-run] [-n] [-x] [--xex] ATR [ATR ...]

|
|
-l, --lower convert filenames to lower case
|

|
|
files)
|
|
-x, --extract extract files
