Romcenter

I'm just setting up my RomCenter for WinKawaks and I went to preferences - emulators and selected the kawaks executable file, but when I press enter on a game on the list to start it up, kawaks loads up but the game doesn't.
Am I doing something wrong, or is this a known bug?
Also I apologize if this has been covered elsewhere.

Thanks.

AFAIK, winkawaks doesn't support command lines, so, you can't bypass the GUI.
