I know this is kind of an old topic to bring back to life, but it fits exactly into what I'm experiencing with the Attract Mode. I've decided to do a major makeover to my GameEx setup, and the next priority on my list is getting Attract Mode working again. I think I deactivated it some months ago, because it stopped working. And now that I've found time to look into it, I see it's the exact same issue, as mentioned above. In GameEx, whenever I start the Attract Mode/Screensaver, it goes right back to GameEx. By running the last action from log.txt in a command prompt, I get an "Error: unknown option: -artwork" message box. Does anyone else have it working? Or am I the only one running it on my cab? I spiced it up with some nostalgic videogame commercials.. I can watch those things for hours. I am by the way not using bezels. And I noticed GameEx is creating an "artworkgameex" folder in my Mame directory. I don't know if that's supposed to happen.
