Clair, the moment I met you, I swear... (I'm dating myself (I'm the only one who will put up with me! )) You need to run Romlister, click on "Settings and Tools", and browse for the three files at the bottom of thw window. In the first line, just point to your mame.exe. The second two lines ask for controls.xml, and catver.ini, both of these files can be found in "C:\Program Files\GameEx\DATA\". After you have those set, click on "Merge!", and Romlister will combine all three. I can't remember if you need to save the file or not, but it will prompt you if you need to. I believe that will aid you in achieving your goal...
