Here are some things you can try.

1. Check that you have a folder cfg in the mame4all-pi directory. If not, then you will need to create one.

2. Check who owns the cfg folder, if it exists, by running the command

ls -ld /opt/retropie/emulators/mame4all-pi/cfg
For changes to be saved, the user should be pi, not root. The output when I run this command is

drwxr-xr-x 2 pi pi 4096 Jul 8 14:21 /opt/retropie/emulators/mame4all-pi/cfg
If you get root as the owner, then you can change the user to pi with the following command.

sudo chown -R pi:pi /opt/retropie/emulators/mame4all-pi/cfg
(I gave pi permission to /opt/retropie to avoid any future problems)
