Okay.I'm sorry, but I don't think it's appropriate to show a different image than the loading screen that a program actually uses, just because it would look better.
In my opinion "loading screen" becomes a bit blurry idea when we talk about disk only games. Loading takes only a second or two there so a distinction if some title screen appears during these two seconds or after these two seconds doesn't matter much.
But I understand your purist approach. So in such case this game doesn't have a loading screen.
The "demo" version differs from normal version as I could notice in such way that it runs in autoplay mode. Load it and the computer will play for you. I hope I'm not messing things up.
