Although you probably already know, you have to get zinc configured outside of GameEx and working prior to incorporating it into the front end. There are a number of tools that you can use to get it working, but basically you will have to go through each game manually and setup the controls, video, etc BEFORE you tell GameEx that you want to use zinc. If you keep the roms in the MAME directory, you will want to make sure you tell zinc where the roms are located. I don't have the info in front of me, but this has been covered in GREAT detail earlier this year. Brian, do you know if the zinc writeup was included in the tutorials? As I recall, you were the one helping get it going for one of the newer members early this year.
