i couldn't find this anywhere either, but for the sake of explore.exe's already mem hogging ways you can drop multi zones into a launcher and only get one window. open your DB with a Gui viewer editer, and find the launcher table add a table here with your new launcher name, then move over to launcher_zones the add in the zones you want your new launcher to handle, format should be
launcher name | short zone name
now that this is all done edit start.bat
Code:
@echo off
start world.exe
echo Waiting for World to finish before starting Zone...
sleep 20
start eqlaunch.exe zones
sleep 60 <!--gives your dynamic zones one minute to start before moving on ---->
start eqlaunch.exe #*#new launcher name#*#
just replace #*#new launcher name#*# with your launcher's name..
