The game is called "Virtual Skipper" (http://www.virtualskipper-game.com/en/) and because it is a sailing race simulator there are just about 100000 users. I found another game that seems to use the same coding. It is called Trackmania and I have found a converter there but it is PHP code. Perhaps I will use this code and port it to perl (http://www.tm-forum.com/viewtopic.php?f=28&t=14924).
The software is not a web based application so I can't change anything there.

Thanks for your support
