sound advice from penelopy grey mate.....
just a couple of points.
the patch to upgrade sh3 on the ubisoft page will read patch 1.3(europe)
dont be confused with this...it is the right patch
secondly...if youre using commander..you will need to update it with the 4 config files that come with gwx2.0
simply copy and paste (or drag and drop) these files into your c/prog files/sh3 commander/config folder.
it will ask if you want to overwrite....click yes.
this should update sh3commander for gwx2.0
if you havent got commander then im blethering for nothing....but you should try it its good mate
