SDLmess is intended for Linux systems, far as I can tell, so you ought not to want the SDL 
patches running under WinXP, Vista, or Win7.

However, ignoring the above, the sdlmess patch is a text file. Change the extension and 
read it with any Windows text program. This patch is intended for people who are able to 
compile their own custom versions of MESS. It can't be applied to any existing version of 
Based on my own problems with MESS (which has frequent source code changes which changes 
can and do effect Coco performance) there is no way to predict that the patch would work 
even if it were for the Windows version of MESS.

Must you use Drivewire4? Have you tried Drivewire3?
