Changing text won't really help in this case. Currently hex editing only will change scripts. Find the script that triggers national dex mode and move it so you somehow get N-Dex early. (I've never tried this before so I'm not 100% sure of script.) NPRE can help you view scripts.

Tools->Make NARC File

Select your folder and the folder where the NARC is saved.

Repack files with kiwi.ds and reinsert narc with Nitro Explorer.

If I remember correctly, any color should work. Just keep/limit it to 15 using your favorite editor (e.g. paint, ...)

Use a program like GIMP to limit the color pallet after you edit the image. Ensure that specific image has a total of 15 colors. Also, when you said "before" and "after", do you mean pallet before and after, or does the actual image change?

Take a look at the BWSE readme.txt. It has everything you need. Unpack with Tinke, repack with Kiwi.

If you use KazoWar's BWTE, the trainer ID box should include the names in the correct order. Copy all of 190 into a text-editor, and compare using line numbers (n-1).

If it's just text, PPTXT works for that too. a/0/0/2 - 236
