If you are seeing a "NOT FOUND" error, you can resolve it with these steps: How to Fix the "dl-1425.bin" Error Obtain the Correct Zip : You need to source qsound_hle.zip from a modern MAME ROM set. Public repositories like Internet Archive often host these files. Verify the File Name : Ensure the file inside the zip is named exactly dl-1425.bin . Older sets might use qsound.bin , which MAME now considers obsolete. Check the File Size : The correct dl-1425.bin file should be 24,576 bytes Renaming Workaround : If you have an older qsound.zip that contains qsound.bin , you can often fix it by: Extracting qsound.bin Renaming it to dl-1425.bin Re-zipping it into a folder named qsound_hle.zip : Place the qsound_hle.zip file directly in your MAME folder alongside your game ZIPs.

This change was made to better organize device-specific ROMs, separating them from the generic qsound.zip which is now considered obsolete.
