D/P stands for Diamond/Pearl. That's the style of textbox that is in my hack, and that's the patch I used. When you patch a file, make sure you're patching it correctly. It shouldn't turn out to be the same. I'll check to see if I have the patch still in my files, but I lost a lot of data so that's probably not likely. Thanks for the offer of scripts, but I'm already myself a good scripter, I did my entire hack on my own as proof. Let me know what happens when you try to re-patch.
In NSE classic (a tool used to edit overworld sprites) there are bookmarks in the program.
One of these bookmarks is the textboxes. you can then edit them just like you would to edit an overworld. I hope that helped.
