Latest update....
I have everything with "Joy_1" deleted except for AD Stick in MAME.
I notice that in games like Tempest, Crystal Castles, and Food Fight, I see in-game analog settings, for the spinner, trackball, and an analog stick respectively.
I can set the spinner and trackball in those games with no issue. In Food Fight, the U360 works. I can't figure out the speed/sensitivity settings worth a damn to get it playable, but the joystick works.
So my issue now boils down to, how do I get MAME to allow non-analog games, like Donkey Kong, Galaga or Q*bert, to "see" the analog stick and load the specific joystick_map settings I have in their (ROM).ini files?
