This happens in both depth 16 and depth 24.
Could you give me some more information about your X server (version, driver)?
I see a very similar problem with my X server : 4.03 that comes with my Mandrake 8, graphic card is a Sis 6326.
I had tested your patch before it was committed BTW but I failed to notice the problem :-/
Anyway, the attached patch is displaying the failing picture correctly. What do you think ?

If I apply your patch, then I see that the red and blue are exchanged when I run vnc as: vncserver :1 -geometry 800x600 -depth 16 -pixelformat bgr565
Without the patch everything is fine. I also checked the formula and I see nothing wrong with it (as long as you are on a little endian computer, but you don't have a big endian x86, do you? ;-).
So the question is why doesn't it work on your system. Can you run The Sims (I assume it's with that the problem happens) with a +bitmap trace? Then look for cases where either the bmp or the dib has "depth=24". Then check the masks to see if they make sense. For example, do they match what you know of your X server. You may also put a trace in Convert_888_to_565_reverse and check that it is invoked at the right time. Do they have a bgr888 dib (unsupported in windows AFAIK, but, except for 1 or 2 shortcuts, supported in Wine)? Maybe it is the DIB masks that are wrong.
Also it would be great if you could run my test application and check whether it displays fine. The line to watch for is the sixth line (rgb888 dib to 565 rgb/bgr bmp and back). I attached it to this email. Here is how to compile and run it: mkdir dib cp dib.c dib cd dib ~/wine/tools/winemaker . ./configure --with-wine=$HOME/wine make ./dib
(note: don't run winemaker . in your home directory!)
As for The Sims, if you can also check the -debugmsg +bitmap output and make sure it's coherent.
