Lol, I just found out, that mame4rpi saves all settings, if there is a directory named “cfg”. Thus, there is no need to recompile like I described before.

Invoke Linux shell and
$ cd RetroPie/emulators/mame4rpi
$ mkdir cfg
$ ./mame
By pressing <TAB> (next left key to ‘Q’) you can enter settings for all games or the specific you are just usinge.
Press <ESC> to leave mame, this will store your settings permanently.
$ cd cfg
$ ls
This should show the setting files for your games and default.cfg for global settings. To reset your config, just enter
$ rm *cfg
