I have a question. I have an upright cabinet running on a PC with a newer version of MAME. In that version, if I set a "non-cocktail" game to cocktail mode, it mirrors the screen in a split so both players see there own "copy of the screen". I am now building a mini cocktail cabinet and would like to use the pi. I am unable to find these options in either mame4all or advancemame settings. Does anybody know how to do it?
Cocktail games you can set to cocktail mode with the virtual DIP switches in mame4all, but I haven't seen the option to do do it with non-cocktail games.
