when making backups of my old Playstation-CDs, some ended to have multiple bins. As I did not want to click my fingers sore, I looked for a solution to batch process them.
I found a solution, that uses MAME's chdman.exe to convert the multi-bin to a chd Image, first, and then the chd to a single-bin. Might not be the most elegant way - but it works.
First you need chdman.exe, then paste the script below in your favorite text editor, change it as required, save it as cmd- or bat-file. Run it and watch it do the work for you.
@REM Multi-BIN Batch conversion script for chdman @REM 2019-01-29 by The_Mole for forum.recalbox.com @REM Requires chdman.exe in the image-sourcepath @REM Switch off unneccessary output @ECHO off REM Clear the screen CLS REM Let's SET the different folders REM Here you SET the source path, where your multi-bin CD-images are. Subdirectories are supported. SET sourcepath="X:\PSX_Multibin_Images" REM Here you SET a path for the intermediate chd file. %TEMP refers to the Windows standard Temp-Folder. REM If you convert a larger batch you may want to conserve writes on your system-SSD and use a ramdisk or HDD, instead. SET workpath=%TEMP% REM Here you SET your output directory, where you want your single-bin CD-images to be stored. REM If you SET it to your source path, your cue-files will be overwritten. SET destpath="X:\PSX_Converted_Images" REM This is a safety catch to make sure, you edit the file, before running it. REM Put a rem-command before the line below to unlock the script. GOTO idiotfilter REM Here we start the loop: For every cue-file in %sourcepath% and its subdirectories execute the commands inside the bracket FOR /R "%sourcepath%" %%R IN (*.cue) DO ( REM Print an empty line ECHO.

Start the next or move on if there are no files left. ) REM This is a jump mark. If you read all comment lines, you know, why it's here. :idiotfilter REM Well... what it says. EXIT
PS: According to the preview, the code block seems not to recognize it as batch-script, so it may look a bit starnge.
