I was involved a long time ago but decided to make the jump to unity3d. I thought realmcrafter was dead, but then I ran into this site. I didnt see the pro source posted anywhere so i decided to release it to this community.
If i recall correctly it should compile in visual studio 2012 just fine. Work has been done on this code its not the original code. This codes still a mess, but its less of a mess than it was at the start. To warn you pro was far from a finished product. I would not suggest this source for those who are inexperienced with code. I wish you the absolute best should you take it upon yourself to continue on with it.
