I've seen your tutorials and understand that, however for someone new to gen 5 rom hacking, they are awesome to look at and inspiring, however most of them go completely over my head, as I'm sure with a few other people (because they are simple for you, but advance for us). The tutorial here actually explained what the scripting function of each hex string did, which was not present in the video. Where in a few videos we were given the actual script to place, most of us look at it like...what am i supposed to do with it. Yes I could have deciphered the script that you gave, however it would have taken a very long time to figure out how it functioned down to a science. Also I don't understand how to replace a script within the hex. I've tried doing so which led to the game freezing, reason I wanted to clarify instead of repeated trial and error until I found a breakthrough.
I'm not sure exactly how to do that. And basically an area of the map crashed, so if i tried to enter say a part of chargestone cave it would freeze the game. How would i go about repointing the header? and also how do i know where said hex script began and ended. By the way i was modifying scripts in the overworld narc if that helps any
there's a few things that are wrong with what you're saying, maleficusu.
Overworlds are entirely different from Event Scripts and Text. You can't mix files.
For NPC editing it's best to use Kazo's tool (although if you can do it in hex I'd do it that way, as NPCE deletes trigger data at the end). My lua script in my tutorial video can check to see if the data has been edited properly if you activate the checking mechanism ingame at the location.
