Well, to correct Ry on a few points...
1. Do as Ry said, go to the sphere web site.
2. Map0.mul is the original map. Map2.mul is Ilshenar (the one you would want to edit). I'm not sure if all map editors support Map2.mul. Contrary to what Ry said, map2.mul is *NOT* supported by every server.
3. I think Sphere does support map2.mul, but I would check the specific features just to be sure. I could be wrong, but again, contrary to what Ry said, I don't think UOXC or UOX .70x support map2.mul, so you'll probably have to use some other emulator for editing the maps as well. Maybe UOXC supports it though, you might want to check.
And to Ry: Read the entire thread next time, he doesn't want to edit the original map, he's asking about Ilshenar (map2.mul)
