I think I have narrowed down the problem as best as I can. Now it's time for
somebody else to give it a look, since I cannot continue due to my lacking
skills.

The problem is that a certain RenderWare structure contains a 32bit field which
is set to 0 in Wine, and to 8 in Windows XP. That's the bit depth, I guess.
Actually Windows XP executes it in fullscreen and maybe it is giving the
correct bit depth to it, while Wine fails to do this.

I have patched rwl20.dll as follows:

0001E910   47 28 09 00  00 00 89 47  1C 89 47 20  8B C7 5F 5E
0001E920   5B C2 0C 00  B9 08 00 00  00 89 48 14  EB 0E CC CC
0001E930   A1 D4 25 7D  01 90 90 EB  EB 8B 48 14  8B 44 24 04
0001E940   51 52 50 E8  18 FF FF FF  C2 08 00 CC  CC CC CC CC 

This code will set the 32bit field with value 8 (as it is on Windows XP) and
continue execution.

However the game crashes elsewhere, so the problem must be solved at the root.

It is strange that the menu works correctly (except the hovering text which is
not displayed at all), while the 3d mode - which uses RenderWare engine -
fails.

The Smacker Videos also show correctly, except that they are at ultra-speed
under certain conditions.
