How can i set up a new Instance

[^Xayo]

So for the Modcraft project i tried to set up a new instance to make some testing etc.
I edited the map.dbc from me, copied the last line (Zul'aman) and just changed the mapid and the sort of the map (0 for normal)
I edited the map.dbc from the emu, copied the thing i did before
I edited the the worldmap_info table like that:

1337 1337 0 0 70 0 0 0 530 Modcraft Testzone 0 0 0
Now i got the problem that the emu wont start.
anybody has experience with adding new maps ?
