NFS: Porsche unleashed

I'm working on getting Porsche Unleashed working. I've made a little progress.
I can get to the main menu but only a few graphics are rendered (though the
animation works).  There is no text and the mouse doesn't work (and perhaps
the keyboard too).

I've put a debug file with +ddraw,+dinput at
http://cablespeed.com/~rcrit/nfs.out.bz2 . I was hoping someone more
knowledgeable could take a look and give me some suggestions.

To get the game to start at all I had to make the following minor change to
winex/dlls/ddraw/ddraw/main.c:

>         if (pDDSD->u4.ddpfPixelFormat.u1.dwRGBBitCount == 0)
>             pDDSD->u4.ddpfPixelFormat.u1.dwRGBBitCount=16;

This gets the splash screen going. It plays the video and sound is ok but
once it gets to the menu I'm stuck.

thanks
