What are you after exactly and why?
I am very curious about the principle of CNCNET.How to enter the game directly,and how to read the map information outside the game?Please forgive my liberty,I've been looking for a long time to read the map, but no results. :D
I believe, on CnCNet YR that's not possible right now. Normally though, you should be able to either right click the game and run as Windowed, or you run the game via -win parameter (can't remember which).
Thanks a lot,but it is infeasible...
