>>35481110It's a good program for mapping, and makes group selections a breeze with the previously mentioned group selection preview, but it's really bad at handling map resizing, events, and walking permissions. I personally make the map the size I want in AdvanceMap, make the map in MEH, and then add the little details, modify the scripting, and add permission data in AdvanceMap again.
It's not perfect at all, but it's something to consider at least. It's also a Java program, and it regularly eats up *all* my RAM, so that's something else to watch out for if you have a low power computer.
If you have any questions in general I've been ROM Hacking on and off for years now and might be able to at least point you in the direction of someone who could know if not answer your concerns
