DS Text Editor is the NDS version of Advance Text.
DS Text Editor is a simple but powerful tool. First you have to extract msg.narc with Nitro Explorer 2 (/msgdata/msg.narc if you are hacking Diamond or Pearl, /msgdata/pl_msg.narc if you are hacking on Platinum or a/0/2/7 if you are hacking on Heart Gold or Soul Silver). Remember that if you are hacking on HG or SS you have to rename the extracted NARC to hgss_msg.narc, otherwise you won’t be able to load it with DS Text Editor.
Open the extracted NARC from the File menu. A list of “Banks” will rapidly appear in the left side list.
These banks contains various messages, thus if you click on a bank the program will load several messages on the top-right list.
To edit a message simply click on the list the message you want to edit and chage it in the text box below.
As you can see, the \n character stands for new line, and in the game it will appear as you see in the program. The \r character is represented with a double new line, because in the game it will be interpretaded as a new dialog box.
Save the text with the proper button in the bottom, but remember that it won’t change the loaded NARC! It will only save temporarily in the RAM. In fact if you edit some text and you exit, the program will ask you to save the edited NARC! Remember to save the NARC from the File menu!
With DS Text Editor you can also search for text in the game. It’s very simple: just click on the proper button in the bottom and the search window will appear.
Just write the text you want to find in the text box and click search. A list will appear in the right with the corresponding bank – message. Click on them for editing.
You can also choose to restrict search results by activating the case sensitive research.
