I have a similar problem I believe. Not sure how to solve it....
I recently installed MALA using the excellent retroGUI layout. I don't know what I did wrong but at some point I lost my list of ALL GAMES on my MAME menu. It now only shows Controls, Genre, Number players, Year, and other basic filters as my first line menu. I've totally lost my initial list of all games. What did I do to mess this up? I don't want to show Genre, Year, etc at the main menu of MAME. I'd rather show All Games, Lightgun games, Trackball games, Favorites, etc.
I've tried to manage the gamelists on the tab within GUI, but nothing takes.
Can anyone help me out here? Please?
Thanks in advance.
