Lately I redownloaded updates of original GeneRally tracks available here and regardless all the past efforts I found couple of tracks had no update satisfying me (either visually or gameplay). So I tried to make some, they all are from World Tour set - Canada, Sweden and USA, the last one has a GRASCAR alt. version too. They follow the rules of last Original Track Update Project 2010.
My thanks goes to James for quick reply with approval of public sharing it here.
Enjoy!
