View source for 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.

== Single command ==
This command creates a dump of your disc. It does also extract subchannel data which is required for the copy protection of some of the games to work correctly. It does save the image in .bin format and also does create a .cue file.

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

== 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
 #
 #  This script is partly based upon the "wesnoth-optipng" script from the
 #  Battle for Wesnoth team.

 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 [http://www.fpsece.net/ PocketISO] via [http://www.winehq.org wine]. There seems to be no native program doing this task in a nice way.
