Hi and Mame Xmas to all!!

.. please help to make my mamewah screensaver working..
This is my .ini but never happens.. no random games, no slideshow.. I also tried with emusaver but it doesn't works. My purpose is to have the launch_random_game.
I have mamewah 1.61 and mame 32 0.61. This is the best frontend and I miss only this feature. Please help me.
