Hi newbie to DS development.

I am trying to make a simple DS art program, using the touch screeen to draw on and press buttons.

I am using framebuffer mode to act as the drawing space, and tiled background mode to act as the buttons on top, I can get the output from each mode appearing individually but never both at the same time and on the same screen.

Can it be done just by changing the graphics modes or would it require a more complicated method
ie using 3D mode, create and a modify a texture as an easel, and have the easel and the buttons as 2D textured quads ?

You'll need to use a bitmap layer for your drawing space, the framebuffer modes display only bitmaps from memory since they bypass the 2D/3D hardware.

See http://devkitpro.org/viewtopic.php?f=6&t=214&start=0 for some discussion on mixing bitmap and tiled layers.
