I don't really have any experience with WINE and Fallout 2, but I know others have gotten it to work just fine. Though these comments are for the Restoration Project, I suppose they also apply to my unofficial patch. Check this. Also, there is no need for the official 1.02 patch and definitely don't use the unofficial 1.05 patch (it has numerous problems). Instead, install Fallout 2 and then install the unofficial patch from my signature (1.02.26b at this time).
