Alright.

I'm not sure this has been done, though I think I may of seen it once or twice. I'm trying to figure out how to make instances. IE, new map files, or Z levels, added on and removed as needed. I'd of course need the map file updated, or similar, so it stays saved on reset for the game i'm developing, but yeah.
