Unfortunately not. It was briefly reuploaded by Dazza himself back in July, but there were numerous issues so it was taken down again so he could fix it in peace. As he is a busy person, he hasn't been able to get it reuploaded yet.
I've downloaded some routes, but I am at a loss, how do I get the routes added? I am in need of a simple how to download instructions as I extracted the files into the correct folders but no matter what I choose I am stuck with the basic 2 maps. If someone who has downloaded them all please...
I would encourage a quick read of this thread, @Road-hog123 covers some basics of map installation.
You need to understand the basics of operating a computer to install an OMSI Map/Bus, Each Archive will include a README file that should include basic information on how to install the specific map/bus.
