Checklist

Provide a clear and concise description of the issue

The Neo Geo CD core seems unable to save content directory overrides. Attempting to do so will give an error message: "Error saving overrides".

I tested 30 other cores and this was the only one to have the problem.

Steps to Reproduce

• Launch any Neo Geo CD title.
• Make a change to its configuration in the Retroarch menu. Set a new overlay, for example.
• Head to the Overrides menu
• Select "Save Content Directory Overrides"

You'll receive the error message: "Error saving overrides."

I haven't encountered this error with any other cores.

Provide any additional context or information that may help us investigate your issue

I SSHd in to look for maybe a permissions issue, but all rom dirs are owned by root and set to 777.

A similar error occurs if you navigate to "Core Options"/"Manage Core Options"/"Save Content Directory Options".

The error in that case is "Error saving core options file."
