ok, i used omar's tutorial "importing boat and wind files form firefox cache" as shown in the vrtool forum.
at first try nothing happened. then i realized that i must first start the clipper game
, so that vrtool understands what game i am in. after re-starting and re-importing, i could see all winds, my boat and friendly boats. it worked well.
obrigado, omar, for producing this nifty tool.
now i have 12 hrs to the start to learn the special routing features of vrtool.
