Loading old voxel terrains. Is it possible? Thread

Hey guys. I'm 26 years old and I've played the Delta Force games since 2000. I love how the voxel terrains works over there and there's no game that reproduces the feeling of that kind of FPS game.
I haven't knowledge in making games, I tried to learn C++, Pascal, Delphi, VB 7 years ago but I failed. I've modding the DF games for fun years ago and I'm interesting in finding a way to load the old .trn (terragen terrains) in a new voxel engine, maybe to get a smooth/sleek render of the terrain.
1. Did you know if it's possible to load the old .trn files in new game engines?2. (...) and try to create a simple game as DFs without a lot of game making knowledge? There's a magical game maker over there?
