1. What you'll need1: Game Dump (You can get this through DDD or titledumper.)
2: MSBT Editor Reloaded
2. Step 1: Finding Your MSBT FileGo to your game dump and go to vol/content/ui. In that folder go to one of these specific folders:
ue: for English people
us: for Spanish people
uf: for French people
Note: These folders are for people in USA. I don't know about Europe or Japan.
You could also go into the cmn folder. In these folders, you will find msbt files. Open any of these in MSBT Editor.
3. Step 2: Editing and SavingGo to a random entry in your MSBT and change the text to it. Their should be 3 boxes on the right. One says "Edit", the other says "Original", and the last one says "Hex View". Just edit the text in the "Edit" box and there you go! Go to file, then save. Your file should now be saved. Place it in Cafiine in the correct directory.
