Maybe that's stupid question and I'm not really sure if anyone still checks this forum but - how can I play stunt maps in sunrise ? When I download them they don't appear in trackmania as normal tracks do

I don't know the answer, but I just wanted to reply and say I was your message. lol
You're probably better off asking in the United forums. Surely there's still a few people around who played Sunrise and might know the answer.

Thanks for answering, I found the solution by myself
