ok sorry bout that i used search just then and it seems the tut got deleted xd
so ill just give you a hint ^_^
you use the warp.csv to which map from the location.csv links with the map you wanna go. what you actually change is the x,y in the location.csv, so ill just do tomb :P. open your location.csv and warp.csv, in the warp.csv you'll see this
1155,1155,1,1,1156,0,0
the 1155 is the index for python and 1156 is the index for tomb, so you see that python index leads to tomb. now go location.csv find 1155
1155,Python Castle,19,0,0,0,0,0,0
then open your pack.d04 with winhex find that, then change it to
1155,Python Castle,19,0,5,0,0,5,0
so just find what index of north morte map in the warp.csv links with ruins then find it in the location.csv and change it so it tele's you there :)
