Creating images of PSX games using Linux

This pages describes a rather simple way for creating images for usage with an emulator like PSX4Pandora. Everything listed here does require the program cdrdao which is often already installed in common Linux distributions once some burner software is installed.

From the command line

This command creates a dump of your disc. It also extracts subchannel data which is required for the copy protection of some of the games to work correctly. It saves the image in .bin format and also creates a .toc file.

First, you must know what device name to use for you optical drive. If you are not sure what your drive's Linux device name is, then you can run this command to find out:

cdrdao scanbus

The result should look something like this:

Cdrdao version 1.2.3 - (C) Andreas Mueller <andreas@daneb.de>
/dev/sr0 : hp      , DVD RW AD-7581S , 4H73

The first part of the second line, /dev/sr0, is the device name of the only optical drive that cdrdao recognizes on this machine. If you have multiple optical drives, they will each show up here. You can distinguish between them by the description following the colon after the device name. The device here is an HP DVD RW Model AD-7581S.

Next, make sure that your disc is in the drive but not mounted. Assuming that your optical drive is called /dev/sr0, to unmount the drive from the command line you can do this:

umount /dev/sr0

(Of course you should substitute whatever device name you got from previous command.)

Assuming again that your optical drive is called /dev/sr0 and you want to name the image GAME_NAME, this is the command you can use to create the image in the current dir:

cdrdao read-cd --read-raw --read-subchan rw_raw --datafile GAME_NAME.bin --device /dev/sr0 --driver generic-mmc-raw GAME_NAME.toc

Of course you have to adjust the parameters according to your desires and your system setup.

Some emulators are finicky and don't like .toc files, or seem to work with some bin/toc file combinations, but not others. Usually .cue files work, so you may want to create a .cue file from the .toc file that cdrdao just made with this command:

toc2cue GAME_NAME.toc GAME_NAME.cue

That will leave both a .toc file and a .cue file in the directory you are working from.

Useful script

Following is a script doing some useful stuff. It does by default rip the current disc in your drive /dev/sr0 into the folder ~/psxrip/ with the name you give as parameter. If the folder does not exist, it is created. It does extract subchannel data by default, saves the image as .bin and creates a .cue.

You can also copy the following code into a text file and make it executable. To do so, lets assume you named the text file psxrip, then run chmod +x psxrip. For usage information just type ./psxrip --help. The script does check if you got the required program installed, if you provided the parameters and all the likes. If you do something that you are not supposed to do, it will print an error message as well as some (hopefully) helpful output.

Here is the script:

#!/bin/bash
#
#  This is a script to create a .bin image with corresponding .cue out of your
#  PSX game discs as backup and/or for usage with emulators.
#
#  Run-time requirements: cdrdao

#  Battle for Wesnoth team.

DRIVE=/dev/sr0

Script for ripping PSX game discs into .bin files with corresponding .cue files.

Usage:
  $(basename ${0}) [{--outputdir} <value>] [{--drive} <value>] [{--no-subchan] [{--help|-h}] [filename]

The parameter [filename] is mandatory. Without it, the script will abort. Plain
spaces in the filename are prohibited!

Available switches:
  --drive       Define the device to be used. If this parameter is not
                provided, /dev/sr0 will be used.

  --help / -h   Displays this help text.

  --no-subchan  Don't extract subchannel data. Subchannel data might be
                required for some PSX copy protection though it *could* create
                problems. Retry with this parameter set if any problems occur
                when trying to use the resulting image.

  --outputdir   Define the folder in which the resulting image should be saved.
                If the folder does not exist, it will be created. If no
                --outputdir parameter is given, the folder ~/psxrip will be
                used.

This tool requires cdrdao (http://cdrdao.sourceforge.net/) to be installed and
available in PATH.

Compressing the images

If you want to compress the images you can try to use the program PocketISO via wine. There seems to be no native program doing this task in a nice way.
