Create .M3U Playlist From .CHD Files (Windows)

m3umaker.ps1

# Get the current directory
$folderPath = Get-Location
# Remove existing .m3u files in the current directory
Get-ChildItem -Path $folderPath -Filter *.m3u | Remove-Item -Force
# Get all .chd files in the current directory
$chdFiles = Get-ChildItem -Path $folderPath -Filter *.chd
# Group .chd files by base name (without the disc part and extension)
$groupedFiles = $chdFiles | Group-Object { $_.BaseName -replace '\s+\(Disc\s+\d+\)$', '' }
foreach ($group in $groupedFiles) {
# Determine the .m3u file name (without disc number and extension)
$m3uFileName = Join-Path $folderPath ($group.Name + ".m3u")
# Create or overwrite the .m3u file and write each .chd file name to it
$group.Group | ForEach-Object {Add-Content -Path $m3uFileName -Value $_.Name}}

Create .CHD From .ISO Files

Windows

ISO2CHD.bat

for /r %%i in (*.iso) do chdman createcd -i "%%i" -o "%%~ni.chd" >> log

Linux

convertFromIsoToChd.sh

#!/bin/bash

# Grab .iso file
for f in ./*.iso
do
	name=${f%.iso} # Remove '.iso' from file name
	chdman createcd -i "$name.iso" -o "$name.chd" --force
done

 

Create .CHD From .CUE Files

Windows

cue2chd.bat

for /r %%i in (*.cue) do chdman createcd -i "%%i" -o "%%~ni.chd" >> log

Linux

convertFromCueToChd.sh

parallel chdman createcd -i {} -o {.}.chd ::: *.cue

 

The below script and the attached version above does not work. Need to test and change accordingly.

#!/bin/bash

# Grab .cue file
for f in ./**/*.cue
do
	name=${f%.cue} # Remove '.cue' from file name
	chdman createcd -i "$name.cue" -o "$name.chd" --force
done

Create .ISO From .CHD Files

Windows

CHD2ISO.bat

for %%i in (*.chd) do (
chdman extractcd -i "%%i" -o "%%~ni.cue" -ob "%%~ni.iso"
del "%%~ni.cue"
) >> log

 

Linux

convertFromChdToIso.sh

#!/bin/bash

# Grab .chd file
for f in ./**/*.chd
do
	name=${f%.chd} # Remove '.chd' from file name
	chdman extractcd -i "$name.chd" -o "$name.iso" --force
done

 

Create .CUE From .CHD Files

Windows

chd2cue.bat

for /r %%i in (*.chd) do chdman extractcd -i "%%i" -o "%%~ni.cue" >> log

 

Linux

convertFromChdToCue.sh

#!/bin/bash

# Grab .chd file
for f in ./**/*.chd
do
	name=${f%.chd} # Remove '.chd' from file name
	chdman extractcd -i "$name.chd" -o "$name.cue" --force
done

 

Create .GDI From .CHD Files

 

 

Windows

 

 

Linux

convertFromChdToGdi.sh

#!/bin/bash

# Grab .chd file
for f in ./**/*.chd
do
	name=${f%.chd} # Remove '.chd' from file name
	chdman extractcd -i "$name.chd" -o "$name.gdi" --force
done

Create .CHD From .GDI Files

 

 

 

Windows

 

 

Linux

convertFromGdiToChd.sh

#!/bin/bash

# Grab .gdi file
for f in ./**/*.gdi
do
	name=${f%.gdi} # Remove '.gdi' from file name
	chdman createcd -i "$name.gdi" -o "$name.chd" --force
done

Introduction

The file formats to adopt for CDs and other optical supports.

We have talked about a format, derived from researches we had on MAME, in order to be able to represent these supports in a compressed way, without losing the integrity of the data and that these can remain scrappable.

This format is the CHD (Compressed Hunks of Data), datas that could be useful for SEGA CD, PS1, PC Engine...

Unfortunately, the classic user will have difficulties to use the converter, which is a command line executable.

So here is a Zip file, with automated scripts, to convert from BIN+CUE (Redump format) to CHD, and vice versa.

It has been added also for the GDI format, which is for the Dreamcast.

For PS1 games protected by LibCrypt, normally you have SBI (Subchannel Information) files, you keep them and put them with the CHDs, otherwise your games will not pass.

If you ever lose them or make a bad manipulation, these files are available on the files of each corresponding disk at Redump, next to the re-downloadable CUE files.

Software

You can download the software by clicking on CHDMAN.zip below.

Convert your game from BIN/CUE or GDI to CHD

You can also run the .bat file to start the conversion of several games at once.

Convert your game from CHD to BIN/CUE

You can also run the .bat file to start the conversion of several games at once.

Convert your game from CHD to GDI

You can also run the .bat file to start the conversion of several games at once.

Create the .M3U file

In CHD conversion for multi-disk games, you have to make a M3U file to declare all the disks.

The .M3U file is a list of the different CDs for a game that allows you to switch from one CD to another in a simple way by using the disc change combination (Hotkey + L. STICK to the LEFT or to the RIGHT).

Example for the game "Grandia (France)":

• Create a M3U file via Notepad++ named "Grandia (France).m3u".
• In the file, fill in the CHD files of the game:

Grandia (France) (Disc 1).chd
Grandia (France) (Disc 2).chd

• On Windows, you must have the extension view enabled to create this file:
  • Go to View at the top of the Windows Explorer window.
  • Check "File name extensions" at the top right.

• Confirm the extension change

Software

Some Linux distributions can give you chdman via aptitude with the mame-tools package. Some others don't have any mame-tools and you need to build it:

make tools
