MineCrafter Starter

I saw the MinePackage starter kit. It is really cool. The one thing it doesn't have is saving and loading of the world. I looked on the forum and there are some old posts about doing that, but nothing for a while.

I would like to make a specialized mine craft game and was hoping someone could point me in the right direction.

If I understood the way MinePackage worked I might be able to make it work. I gave it a good try, but ran into all kinds of trouble trying to figure out what to save and what to load and the time it took to try to save the millions of clubes that are generated in the default size world.

Can someone help me out here?
