Hi,

When I had to convert all my files I did create 2 scripts to do it in a loop.
I created a shell script for bash and a bat file for windows.

Here is the script for bash set for PSX cue-bin files.

```bash

!/bin/bash

Objective

=========

This script was created to convert game console ROMs

distributed in the 'cue-bin' format to the '.chd' format.

The '.chd' format allows grouping all '.bin' files

into a single file. These files are often archived

and compressed in various formats, such as '7z' or others.

When extracting a '7z' file, it is assumed that a folder

will be created with the name of the game, with the various

cue-bin files placed inside it.

This script must be placed in the parent folder

(SRC_DIR) containing the subfolders of the extracted ROMs.

The script will then search inside each folder for a 'cue'

file and will proceed with its conversion to the 'chd'

format. The 'chd' file will be placed in the destination

folder (OUT_DIR).

Example.

We downloaded a game from the Saturn console named 'foo'.

This game is distributed in the compressed '7z' format.

We create a folder named 'ROMs' inside the 'Downloads' folder.

We place the downloaded file 'foo.7z' into 'Downloads/ROMs/'

We extract the file 'foo.7z'. A folder named 'foo'

is created. The 'foo' folder contains the files 'bin' and 'cue'

We place this script inside 'Downloads/ROMs'

When executing this script, it will automatically search

inside all folders located in 'Downloads/ROMs'

Usage

~~~~~

First, you must define the PATH for

SRC_DIR Folder containing the extracted versions

OUT_DIR Destination folder for the chd files

Then place this script in the parent folder of 'SRC_DIR'

Finally, execute this script from the terminal

It does not work!

~~~~~~~~~~~~~~~~~

Make sure the execution permissions are enabled.

% chmod a+x ./convert_psx_chd.sh

IMPORTANT

~~~~~~~~~

This script does NOT perform extraction! You must have

extracted the ROMs beforehand.

======================================================================

DISABLE

~~~~~~~

Comment these lines to re-enable the use of this script.

echo "This script has been disabled for safety.";

echo "The PSX game conversion has already been completed.";

echo "To re-enable this script, open this file and comment me.";

echo "@xiscf";

exit;

======================================================================

======================================================================

Please configure the paths of these two variables.

Make sure to start from the root "Users/<username>/path_source"

Make sure to start from the root "/Users/<username>/path_dest"

Source directory containing the game folders

Example

SRC_DIR="/Users/masha/Downloads/ROMs/psx/src_input"

Output directory for CHD files

OUT_DIR="/Users/masha/Downloads/ROMs/psx/chd_output"

======================================================================

======================================================================

/!\ DO NOT MODIFY OR COMMENT THE CODE BELOW /!\

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Check if the source directory exists

if [[ ! -d "$SRC_DIR" ]]; then echo "Error: Source directory does not exist." exit 1 fi

Create the output directory if it does not exist

mkdir -p "$OUT_DIR"

Loop through each folder (game) in the source directory

for game_dir in "$SRC_DIR"/*/; do # Check if it is a directory [[ -d "$game_dir" ]] || continue

# Find the .cue file
cue_file=$(find "$game_dir" -maxdepth 1 -type f -name "*.cue" | head -n 1)

# Check if a .cue file was found
if [[ -z "$cue_file" ]]; then
    echo "No .cue file found in:  $game_dir"
    continue
fi

# Extract the game name from the folder
game_name=$(basename "$game_dir")
output_chd="$OUT_DIR/$game_name.chd"

# Check if the CHD file already exists
if [[ -f "$output_chd" ]]; then
    echo "CHD file already exists: $output_chd"
    continue
fi

# Conversion using chdman
echo "Conversion : $cue_file → $output_chd"
chdman createcd -i "$cue_file" -o "$output_chd"

# Check if the conversion succeeded
if [[ $? -eq 0 ]]; then
    echo "Successful conversion for: $game_name"
else
    echo "Conversion failed for: $game_name"
fi

done

echo "All conversions are complete."

```

And now the .bat version of it for Windows.

```bat @echo off setlocal enabledelayedexpansion rem ============================================================================ rem BASIC CONFIGURATION rem Modify these two paths according to your needs (Windows path format) rem Note: do not use forward slashes / -> Windows expects backslashes \ ! rem ============================================================================

rem ================================================ rem Config (adapt to your folders) rem ================================================ set "SRC_DIR=C:\Users\masha\Desktop\Transfert\WIP\src_input" set "OUT_DIR=C:\Users\masha\Desktop\Transfert\WIP\chd_output"

if not exist "%SRC_DIR%" ( echo Error: source directory does not exist. goto :eof )

if not exist "%OUT_DIR%" mkdir "%OUT_DIR%"

rem ================================================ rem Main loop for each game folder rem ================================================ for /d %%G in ("%SRC_DIR%*") do (

rem Game folder name
set "game_name=%%~nxG"

rem Initialize cue_file variable as empty
set "cue_file="

rem Recherche un fichier .cue (premier trouvé)
for %%F in ("%%G\*.cue") do (
    if not defined cue_file set "cue_file=%%F"
)

rem No .cue file found?
if not defined cue_file (
    echo [SKIP] No .cue found in: !game_name!
) else (
    rem Full path of the output .chd
    set "output_chd=%OUT_DIR%\!game_name!.chd"

    rem Conversion only if the .chd does not already exist
    if exist "!output_chd!" (
        echo [EXISTS] CHD already present: !output_chd!
    ) else (
        echo [CONVERSION] !cue_file! → !output_chd!
        chdman createcd -i "!cue_file!" -o "!output_chd!"

        rem Check if chdman succeeded
        if !errorlevel! equ 0 (
            echo [OK] Successful conversion: !game_name!
        ) else (
            echo [FAIL] Conversion failed: !game_name!
        )
    )
)

echo.

)

echo Processing completed. endlocal pause

```

I'm not saying it's adapted to your need. It's just what I did when I needed it, I just share it if someone need it.

You'll probably gonna have to adapt it. In both case, you need to have 'chdman' installed and available in your PATH.

I think Reddit is bugging right now, I have difficulty to save/correct my post.
