From GameBrew - a wiki dedicated to Video Game Homebrew.
PPaPP (Position Précise au Pixel Près) is an application that it will show you the precise position of the appointed pixel on the Nintendo DS.
The concept is for developing DS homebrew where an element (such as sprite, background) needs to be placed on the x y coordinates, and tweaking them as they go.
Operate with Stylus.
