I just ran the mame4all-pi executable and it loads with NO ROMS FOUND. Is there a way to rescan or configure mame4all directly?

EDIT: Found the mame.cfg file, changed the roms directory and so when I run I run it directly, the mame screen comes up and then just kicks me back to prompt.

EDIT 2: Got the standalone mame4all in console working with the “sudo ./mame contra” command. Still can’t get mame4all to show up in the main menu while all other emulators and apps work great.
