Advmame configuration changes doesn´t save at all

[mjh]

Hi,
I can finally access to advmame on came configurations.
Can even change the conf, and it works well. Untill I restart the game. After restart confs are in the default ones. So somehow I can´t save the changes I am doing trough game conf UI (TAB).

Any advice, is the conf file somehow protected?
