I checked the GameEx forums, couldn't find precisely the answer, but I'm using
--use-config-file=zinc.cfg --use-controller-cfg-file=C:\Emulators\Zinc\ctrlr\[ROMfile].ini
as my line in the config, then I thought about the lconfig.ini file that has all the appropriate command lines in there. Do I need that in the config line instead? I get returned to the menu when I do it my, read:wrong, way. When I get it working, I'll be more than happy to post it to the GEx forum for other poor saps.
