Naybe you could do what I suggested when extracting mods: Get some 7ZIP or such (I haven't checked if it works), but that should make the calls to files go through WINE that'll handle the case. Of course it'll slow down things, but I think that if that problem exists, it can be fixed like this. Or just extract to a temporary folder, then make a script to lower-case or upper-case everything and run this script on both the temp folder and the destination folder. After that move temp into dest and it _shpuld_ work. Just a suggestion. Oh and: > Right.
