Sorry, i don't think so. I'm not interested in a seperate prefix for windows 95 games. In fact that dir would eventually get deleted too, and i would have to change the app compatibility again etc. I'm trying to make the games i can portable. It's surprizingly possible (copy missing dlls to the game dir etc), but in areas where windows has no alternative, i'd like to at least keep portable in linux installations. Copying a .wine dir just to set compatibility mode (a possible solution) doesn't seem "portable" enough. As microsoft never did introduce a public command line tool for windows compatibility installed by default, this seems slightly offset from wine goals, but it can't harm - it's just the cmd line equivalent of a volatile winetricks setting.
