Last Month the Japanese try to retrive this mod a little bit more. They played in the at 2pm CET. At the moment the gametracker,com Server Monitorring is off. Hope soon they turn it on. The ranking seems to work.
Im not sure where your going wrong skins but i have already imported one of the hydro racers into a map for fun its just a case of putting the files in the correct folders, for example the .sm and .rs go in the standard mesh folder of the map, textures go in the texture folder etc then make sure your init.con and other .con files are telling the map to load the files youput in the folders.
