If Nintendo DSi/XL support pressure, the hardware registers to read the values are not the same as for DS/DS Lite. Try Colors! 1.06 (which doesn't detect DSi consoles) on a DSi. In the settings menu, it allows you to set the pressure by pressing hard on one section of the screen and soft on another. On a DS/DS Lite, the numbers change depending on how hard you press. On a DSi, they're always zero. There's another program that supports pressure to control brush size, called animanatee. Same deal, it always returns 0 for the pressure values on a DSi. Nintendo either changed the hardware, or disallowed the low level access to the touch screen controller that returns these numbers. Colors 1.1 still fakes pressure on DSi by making opacity increase at a fixed value, but you can't go from max opacity to light mid stroke like you can on a DS lite.
