This is not dead. Just letting you know, because I know you're thinking "Loadingue is at it again with his false promises"...
As you should know, I've been working with a guy called Gondallez to convert the maps. He's dedicated, perfectionist and a great help with many things. By now, the project belongs more to him than to me, actually.
I think I can safely assume that the both of us have gone further than anyone else in the converting of CSGO maps (and L4D2) to older Source. All we need now is to produce some results.
Edit: A few minutes ago, Gondallez made a major breakthrough in porting CSGO maps. People have had a critical problem ever since they've tried, and we've found a way to solve it.
The revolution is here!
