Hello, I modified a bin file extracted from a chd file, I would like to re-import this file back into the chd. Is there a script to reimport bin files to a chd file ?

By BIN files, I assume it was the game's images or the files inside that image? If it's the image itself, just use the same chdman tool to recompress it back to chd (You can find the tool included on the latest MAME release). Just make sure the modified bin images has the same name as it was referenced in the GDI/CUE file.

Code:

chdman createcd -i game.gdi -o game.chd

or

Code:

chdman createcd -i game.cue -o game.chd

But if it's the file inside the image, then you need to reinsert that file back to the images or even rebuild the image with the modified files inside. Then recompress it with chdman with the command line above.
