Notepad DS is as helpful as notepad.exe for Windows. Write and save any kind of text and keep it save on your NDS.

Release notes:

The loading was glitchy, so now you can only view your saved note. Will add more save slots in some time. Update can be downloaded from the first post. Remember you must play this on a real DS, not in an emulator, or the save functions won’t work.
